實體與虛擬的消長



最近有兩個被媒體大量報導的新聞, 一個是Amazon的Kindle電子書, 一個是Pew Research Center替People-Press.org所做的分析資料

這兩則新聞看似沒太大相關, 但其實都在說明實體與虛擬的消長, 到底實體與虛擬間會發生什麼變化呢?

上圖是People-Press.org的文章"Internet Overtakes Newspapers As News Source"所分析的結果, 顯示到2008年美國的新聞來源網路首度超越報紙(各為40%及35%), 但電視新聞的比例仍然達70%

而對於18~29歲的人所得到的資料, 新聞來源依靠網路與電視的比例各是59%, 而報紙只佔28%, 也就是說年輕族群的網路新聞已經與電視新聞具備相同的比重

另一個則是Amazon的Kindle:


Kindle售價359美元, 下載電子書每本9.99美元, Kindle具有無線功能, 也就是一個可以無線上網的電子閱讀器, 相關新聞可以看這裡: "Kindle爆紅 電子書將起飛"

Kindle是否真的如新聞所說的"電子書將起飛"? 其實還在未定之天, 光就使用介面來看, 功能雖然齊全但與傳統閱讀習慣仍舊差異頗大, 過多按鍵及不方便的輸入也還有很大的改善空間, 如果Kindle能夠使用iPhone的Touch介面, 也許會比較能夠被更多人接受

但是這兩則訊息都透露了, 實體的優勢已經逐漸消失, 除非能夠有比虛擬更豐富的內容或發揮虛擬所沒有的功用

美國質疑ICANN近期釋出網域作法


國際域名與位址管理機構(ICANN, The Internet Corporation for Assigned Names and Numbers)預計增加數百個新的頂級域名作為.com替代域名的建議日前遭遇反對意見,美國商務部認為此計劃可能不利於消費者及域名市場

ICANN計劃明年年初開始接受新的頂級域名的競標, 但美國商務部國家通信和資訊管理局認為潛在利益是否一定大於潛在成本仍然需要評估, ICANN原計畫推出200到800個新域名接受競標, 每個價格在美金$185,000, 年費美金$60,000

美國商務部國家通信和資訊管理局認為ICANN應該更清楚說明價格結構, 並且評估是否會對目前DNS(Domain Name System)的穩定及安全發生影響

目前gTLD (Global Top-Level Domain)為21個, 如com/org/net...等, 美國商務部國家通信和資訊管理局認為 "The DOC is unconvinced that new gTLDs will alter the preference for .com domains, and fears that a huge number of new gTLDs will simply force companies to register them in order to maintain and redirect appropriate traffic".

ICANN雖然是一個獨立機關, 但是美國政府仍舊對於ICANN重大議題有控制權, 因此ICANN想要在明年大量釋出域名, 變數仍究存在

就實務面來看網路域名, 目前gTLD之外尚有ccTLD(Country Code TLD), 對於企業而言, 註冊域名已經是一個沉重的負擔, 假設想要保有ACER的網路身份, 除了ACER.COM外還需要ACER.COM.TW, ACER.TW, ACER.CO.JP, ACER.CO.UK ... 如果真的要滴水不漏的保護, 可能要註冊數十個以上

如果再釋出更多網路域名, 最頭大的可能是跨國企業了, 而目前網路域名是否真的不夠用呢? 其實大多都只是註冊起來備而不用, 或是待價而沽, 真正的解決問題不是釋出更多網路域名, 而是健全網路域名市場與遊戲規則, 讓需要域名的企業可以在合理的價格取得, 並且更清楚定位商標與域名

Bounce Rate與New Window的關係



我們於前面文章"BounceRate是否影響SERP?"談到Bounce rate是一個重要的根據, 可以讓你知道哪些頁面無法讓讀者停留或繼續閱讀, 雖然Bounce Rate並非影響SERP的前因, 但是降低Bounce rate或盡量讓Bounce Rate真正反映讀者的行為是重要的作為...

我們根據Wikipedia解釋Bounce Rate, 可以知道以下會造成Bounce Rate:

-Clicking on a link to a page on a different web site
-Closing an open window or tab
-Typing a new URL
-Clicking the "Back" button to leave the site
-Session timeout


現在如果有幾個情況 :

(1)點選到你的網頁, 沒有閱讀就離開 (可能關閉、另外輸入URL、或back到外部網站)
(2)點選到你的網頁, 點選link到同個網站的另外頁面(在本window)
(3)點選到你的網頁, 點選link到同個網站的另外頁面(在新開的window)
(4)點選到你的網頁, 點選link到外部網站(在本window)
(5)點選到你的網頁, 點選link到外部網站(在新開的window)
(6)點選到你的網頁, 到session timeout(default 30 min)都沒動作

哪幾個會造成Bounce?

(1)最沒有爭議, 絕對是造成Bounce, (6)就有些爭議, 因為有可能讀者在session timeout都還在閱讀該頁面, 但是還是會被算成Bounce, 所以根據(6)的推理, 每個頁面不應該太長, 否則就算有閱讀都會算成Bounce,(2)則沒有疑問的, 絕對不算Bounce

而(3)(4)(5)的狀況就比較複雜, 我們來探討Google Analytic的Bounce如何產生

我們先看(4)(5), Google Analytic code因為只是在自己的頁面執行, 當自己的頁面A點到一個外部link, Google Analytic code當然不知道, 因此若由自己的頁面A在本視窗連到外部link, 自己的頁面A就算關閉, 如果由自己的頁面A在新視窗連到外部link, 頁面A的視窗須等session timeout才算bounce

因此如果自己頁面連到外部link最好以開新視窗的方式

再來看(3), 當一個視窗開啟就形成一個新的session, 因此如果自己頁面連到內部link最好以開本視窗的方式

也許你會問: Bounce Rate並非影響SERP的前因, 那注意Bounce Rate作啥?

讓Bounce Rate盡量正確可以讓Bounce Rate成為修正網頁的根據

如果你以本視窗方式連到外部link, 讀者有繼續閱讀但是同樣會形成bounce, 如果你以新視窗方式連到內部link, 讀者有繼續閱讀但是同樣會形成較高的bounce, 因此修正這些做法可以讓Bounce rate更精準

也許你又會問 : 啊! 我有一堆違反上面所說的怎麼辦 ? 豈不是改到歪腰? 其實只需從現在起注意修正或盡量修正即可, 不需刻意把所有網站的開視窗方式都全部修改

所以記住 :

-- 單一頁面不要太長, 以免因session timeout造成bounce
-- 如果自己頁面連到外部link最好以開新視窗的方式
-- 如果自己頁面連到內部link最好以開本視窗的方式


並不是說如此就可以有好的SERP, 而是就機率來說, 以上3個做法可以讓bounce rate盡量符合實況, 可以讓Bounce Rate成為修正網頁的根據

Search Engine Optimization 搜尋引擎最佳化的幾個問題(4)



延續之前文章

"Search Engine Optimization 搜尋引擎最佳化的幾個問題(1)"
"Search Engine Optimization 搜尋引擎最佳化的幾個問題(2)"
"Search Engine Optimization 搜尋引擎最佳化的幾個問題(3)"

我們繼續來談其他問題...

Q: I have a website in 5 languages (and I cannot buy 5 different localized domains), which option is the best? To have different subdirectories (domain.com/en) or to have different subdomains? (en.domain.com)
如果網站有五種不同語言的內容, 網址應該如何取捨? 子目錄或子網域?

A: both versions are fine. I personally generally recommend using a subdomain when the sites are completely different and using subdirectories when it's more or less a shared site, but it's up to you.
當網站是完全獨立的可以用子網域, 若共用則使用子目錄


以上回答如果有聽沒有懂, 請參考:

搜尋引擎最佳化 : subdomain 與 subdirectory
搜尋引擎最佳化 : subdomain OR subdirectory

Q: If my sub domain got high Page Rank, how far it will contribute to the main domain?
次頁的PR是否會貢獻給主頁?

A: PageRank is on a page-by-page basis. The PageRank of a page (on a subdomain or not) is based on the links to it.
不會


雖然PageRank是以頁面來計算, 不會貢獻給上層網頁, 但是如果適當調整link, 可將link的PR貢獻給上層或其他網頁, 因此監看各頁的PR還是必須進行的

Q: Recently you posted on the webmaster central blog that you would suggest to not rewrite dynamic urls to static. Is there penalties for sites that rewrite? Would you suggest changing if a site has 5+ years history? Can you discuss further? Thanks.
將動態URL改寫成靜態URL影響如何?

A: great question. If your site is already doing well and you have rewrites, then you're probably doing them properly so please don't worry about it.
Feel free to spend time on your content and business! Yay! :)
In our blog post, we wanted to discourage new sites, or less experienced webmasters, from feeling they HAD to use rewrites. We've improved our processing of dynamic URLS, so there's no need for newer webmasters to be afraid of them any longer.
沒有必要


在以往靜態URL的SERP比動態URL要好, 但是目前已經沒有差異

Q: Sub-Domains are considered as a new site for Search Engines, if a 5 years old site which uses forums.domain.com, www.domain.com now plans to add shop.domain.com and download.domain.com will this take another few years for both new domains to get rank?
舊站的PR是否能夠貢獻給新的子網域站台

A: PageRank is purely at a page level, so if you forums.domain.com has a high PageRank and links to new urls such as download.domain.com, that PageRank will flow immediately.
如果舊站有高PR, 並且指向新站, 新站很快就會有影響


不管子網域或次目錄等, 應該善用高PR的頁面, 逐步培養新的頁面

Q: Will it make any difference between a shared IP and a dedicated IP on SEO or search results, as opinions are divided on this aspect?
共用IP與獨立IP對於SEO有何影響?

A: most of the web is on shared IP addresses, so it doesn't make much sense for us to give those on dedicated IP addresses any advantages. That said, if your server is struggling with the load of your website, it might make sense to move to a dedicated server that helps to make sure that your users are happy when visiting your website.
沒有


PageRank與SERP並不會以IP來ranking, 只會以IP來判斷區域

Q: If I 301 redirect a well-ranked page to a new domain with the exact same content, will all of the rankings be replaced with the new domain once it has been indexed? How long after indexing can we expect the swap? And is the same thing true for 302s?
301 redirect是否會轉移PR, 那302呢?

A: If you're moving from one URL to another (even if it's on a different domain), ranking signals can be passed via a 301. A 302 is used for temporary redirects, so this is less likely to transfer ranking signals.
301 redirect可用於網站轉移, 302只是暫時


詳見 : SEO策略: PR5+PR4=PR6?

Q: Google takes 200 signals for ranking a query and PR is one among those. If that is the case, why is it still showed prominently on toolbar. Any possibility of seeing PR info dropped from Google toolbar?
之前說過Google使用200個因素來判斷SERP, 為何toolbar要顯示PR...

A: PageRank is just one signal that we use, but it's also one of the easiest metrics to show to users and an easy one to understand where the metrics come from. So I think it's something that still provides value to users and still makes sense to show to them in the Google Toolbar.
因為是一個最早也最簡單說明的因素...


本站文章已經就各種不同因素說明, 200個因素要說好久...慢慢再說明啦

Q: How often does your search algorithm change?
Google多常修正演算法?

A: We change the algorithms all the time - last year we had over 450 changes.
經常, 去年修正了超過450次


參考前文"SEO觀點 : SEO面對的是巨變的環境"

Q: Should I be using hyphens instead of underscores in my URLs to improve a page's rank?
我應該在URL使用底線還是中線?

A: For the time being, I would recommend still using hyphens instead of underscores. If you're already using underscores and that's working fine for you and your rankings, it's not worth switching. But if you're doing a new site, then I would go with hyphens.
中線較好


參考: SEO策略 : 如何產生更多的backlink?

Q: Does link: gives exactly the number of back links to a site?
link:這個指令是否列出所有backlink資料?

A: The link: operator only shows a sampling of links to a site, so it may not show all of the links that Google knows about. To find more information about backlinks to your own site, we give verified site owners more information about backlinks in Webmaster Tools:
http://www.google.com/support/webmasters/bin/answer.py?answer=55281
非也, 只是列出代表性, 並非所有backlink, 可以參考上述連結


只有在Webmaster Tools中的資料才是完整資料

Q: If my website "A", linking to website "B", and "B" linking back to "A" - am I going to be penalized? Does linking strategies still work?
如果A頁連到B, 然後B又連回A, 是否會被懲罰?

A: Participating in linking schemes to impact ranking is not advised it's against the webmaster guidelines.
http://google.com/support/webmasters/bin/answer.py?answer=66356
The best linking strategy is to create a site with unique content or services that people want to link to. Then publicize it.
想要影響ranking的話...是的


link schemes需要好好想想, 並非都不行, 但某些狀況不行, 請詳讀上述link

Q: Are you going to focus more on personalised search? If so, these results we currently look at won't really matter, as different sites will be at #1 for different people, right? - thank you :)
是否某人看到的SERP會異於他人看到的?

A: that's right -- with personalized search it's possible that each user sees slightly different search results. We try to make those search results unique and compelling enough to make the user go visit and stay on the sites listed -- so if your site is really awesome, chances are high that we'd be recommending it to users as well :-).
是的

Search Engine Optimization 搜尋引擎最佳化的幾個問題(3)



延續"Search Engine Optimization 搜尋引擎最佳化的幾個問題(1)", "Search Engine Optimization 搜尋引擎最佳化的幾個問題(2)", 我們繼續來談其他問題...

Q: In addition to a XML sitemap, does it make any sense to have also an HTML sitemap on the same website? Does HTML sitemap helps improve the rating?
除了XML的sitemap外, 有HTML的sitemap對於rating有幫助嗎?

A: A HTML sitemap file can help search engines, especially those that don't use XML Sitemap files. Also, the 404 widget in Webmaster Tools (which you can place on your 404 pages) will use "/sitemap.htm" and similar files to help users to find the content they're looking for. So yes, I would recommend making HTML sitemap files, however I'd focus on the user and not the search engines.
是的, 但是是指對使用者有幫助


HTML sitemap可與Webmaster Tools 404 pages結合(也就是當找不到網頁時), 可以指向HTML sitemap, 此舉可以讓讀者繼續停留在網頁上

Q: Recently went through a rebranding of our company name. The old domain name was successful in page ranking, however the new domain name has terrible page ranking. Do 301 redirects transfer the site equity from the old domain to new domain?
當移動網站時, 301 redirect可否轉移ranking?

A: This is a pretty common question, so we actually did a blog post about it recently. In short, 301's are the best way to retain users and search engine traffic when moving domains. You can find the full post here: http://googlewebmastercentral.blogspot.com/2008/04/best-practices-when-moving-your-site.html
移動網站時可參考上述連結


這個問題我們在"SEO策略: PR5+PR4=PR6?"也已經談過

Q: Is the bounce rate and speed taken into account when ranking a page? i.e. if you see a searcher click on a result then return very quickly and choose another result, is the first page ranked lower?
Bounce Rate是否會影響SERP?

A: assuming that users will be jumping out of a site like that, there's a high probability that they won't be willing to recommend it to others (or come back themselves). So yes, indirectly at least, if a site is made in a way that users run away right away, then chances are that we might not be recommending it as much as other sites that users like (and recommend to others).
間接來說, 是的


我們在"BounceRate是否影響SERP?"也談過啦

Q: Many believe that to rank well, you simply need "quality" backlinks. But how important is having your keywords in the , and throughout your site? Is keyword density of any importance to show what the page is about? What % is suggested?
有人認為高品質的backlink是重要因素, 並且關鍵字密度比例應如何?

A: Links are just one factor involved in Google's ranking of pages. We look at both on-page and off-page content, so what you have on your page can be an essential part of ranking. However, there is no recommended "keyword density." Your content should be high quality and written for users. If you try writing for search engines, the language can become very unnatural, which may end up hurting you more than it helps.
on-page與off-page都是重要因素, 沒什麼關鍵字密度比例問題, 只需產生高品質的內容...


請參考之前"SEO策略 : OnPage & OffPage SEO"

Q: Does inconsistent capitalization of URLs cause duplicate content issues and dilution of page rank? For example www.site.com/abc vs www.site.com/Abc. On Windows hosts, these are the same page, but are different pages on Unix hosts.
URL上的大小寫是否造成不同的URL?

A: based on the existing standards, URLs are case-sensitive, so yes, these would be seen as separate URLs. Since the content on the URLs is the same, we'll generally recognize that and only keep one of them. However, we'd recommend that you try to keep all links going to one version of the URL. Keep in mind that this also applies to robots.txt files.
是的, 如果出現大小寫不同的URL指向同一內容, 我們只留其一


在使用英文大小寫需注意, 在UNIX類的機器是大小寫不同, 而windows是大小寫視為相同, 最好在網址與robots.txt上都保持一慣性

Q: Does appearing high in image searches help improve the host sites PR and appearance on standard searches?
影像可被搜尋是否對PR有幫助?

A: Thanks for the question Andy. Well-optimized, relevant images could definitely help increase traffic to your site, especially with the introduction of Universal Search, where we mix images, videos, and more into the web search results.
是的, 影像可被搜尋可以增加流量


在網站的影像影音檔應注意檔案名稱與alt的內容, 以便能夠被搜尋

Q: Is there a META tag we can use to tell Google the geotarget (country) of a particular webpage?
在meta可否標示地區?

A: we don't have META geotargeting capability at this time.
沒有


要讓網頁能夠有地區或語文區分, 可參考

Search Engine Optimization 搜尋引擎最佳化的幾個問題(2)



延續上一篇"Search Engine Optimization 搜尋引擎最佳化的幾個問題(1)", 我們繼續來談其他問題...

Q: Do inbound links from other sites owned by the same company help or hurt rank? 自己公司的自我連結是否有益或有害於ranking?

A: I've see SEOs have 1000 or 2000 different domains and cross-link them. I definitely would not recommend that... if you run a sporting goods site, and you link to your sister companies for camping and tailgating equipment, that's good for the user...Put yourself in the user's seat, and do what makes sense for these links. Good luck! SEO式的胡亂連結並不推薦, 但合理的連結可以接受, 只要站在讀者的角度有意義的連結都算OK


最後那句Good luck...有點毛骨悚然吧, 有些好自為之的意涵, Google並非全然沒發現non-sense link, 只是要不要處理的問題, 如果被處理到...就全盤皆輸了...還是Good luck...保重吧, 合理的連結可以接受, 但是如果是無意義的大量連結就盡量避免吧

Q: Will Webmaster Tools ever give us an option to "disassociate" from sites that link to us? This feature exists in Yahoo's Site Explorer, but not Webmaster Tools. 是否在Webmaster Tools提供拒絕對方連結的功能?

A: So far because we work really hard to make it so that one site can't hurt another site, we haven't really offered this...So that's a challenge, and since we haven't seen a need for it yet, that's why we haven't offered it yet. 對方的連結並不會影響, 目前沒看出有這個需求


Google的演算法中, 他站的連結並無法去搞亂另外站台的ranking, 真的如此嗎?

Google的假設是壞站可能會連到好站, 但好站不會連到壞站, 但是如果你有透過交換連結, 你如何知道對方何時會變成壞站? 更多詳細內容, 我們後續再討論

Q: Does Google plan to let us see rankings/positions of keywords in the webmaster tool? 是否會在webmaster tool工具中, 可以查詢關鍵字的ranking?

A: We already do, for a limited number of keywords, in the "Top search queries" section of Webmaster Tools. While we generally don't comment on future features or plans, expanding this functionality is certainly an idea that's been suggested to us. 已經如此做了, 增強的功能也進行中


Google Webmaster Tool中的查詢關鍵字ranking, 目前功能並不完善, 顯示的排名也似乎與實際資料有落差

Q: Until recentley (the last six months or so) a high ranking was achievable by submitting articles to article directories (providing they were 40%-60% unique), it no longer seems to be the case. Have links from article sites been de-valued at all?
目前一些文章目錄網站的效果是否降低?

A: In my experience, not every article directory site is high-quality. Sometimes you see a ton of articles copied all over the place, and it's hard to even find original content on the site. The user experience for a lot of those article directory sites can be pretty bad too. So you'd see users landing on those sorts of pages have a bad experience.
If you're thinking of boosting your reputation and getting to be well-known, I might not start as the very first thing with an article directory. Sometimes it's nice to get to be known a little better before jumping in and submitting a ton of articles as the first thing.
有些文章目錄網站品質並不高, 並不建議利用文章目錄網站來提高曝光度


文章目錄網站品質不一, 所以在把文章丟到文章目錄網站前, 應先好好審視品質, 否則只是白費功夫, 但是優秀的文章目錄網站還是具有一定的效果

Q: For SEO, I'd like to improve my rankings by removing technical obstacles (starting with dynamic URL parameters), what are the most important site fixes to make and how can I document before and after success metrics using the Google Webmaster Tool?
如何有效找出網站技術缺失並修改?

A: To check the crawlability of your site, I would recommend crawling your site with a crawler like Xenu's Link Sleuth (freeware, for Windows). Doing that gives you a rough look at how search engines view your site and can point you towards areas where crawlers get stuck in a loop or start crawling duplicates based on the URL parameters.
應先了解搜尋機器如何抓取你的站台


以搜尋引擎的角度來審始自己的網站是很重要的, 可以利用Google工具或一些免費工具來看哪些抓取會有困難, 然後修正

Q: Are .gov and .edu back links still considered more "link juice" than the common back link?
如果有被政府或教育單位連接, 是否比一般連結有效?

A: This is a common misconception--you don't get any PageRank boost from having an .edu link or .gov link automatically.
沒有分別


常常有人認為被政府或教育單位連接, 其PageRank/SERP表現會更好, 其實不是, 只是可能因為能導入流量而引起效果, 與gov/edu並沒有直接關係

Search Engine Optimization 搜尋引擎最佳化的幾個問題(1)



Google搜尋引擎真正的運作機制一直是一個黑盒子, 但在Live Chat Q&A當中, 可以透過一些對話來了解大家關心的重點及解答, 我們來研究這些對話並且解析出到底哪些才是搜尋引擎最佳化的真正核心問題...

Questions and answers from the third online Webmaster Chat from October 22, 2008記載了所有詳細的對話, 但是光是看這些對話只是一些公式化的官方回答, 我們一一來解析中間的奧妙
Q: What weight does the age of a site and the amount of time a domain is registered for have on it's search placement? 網域名稱的註冊時間與長短是否影響搜尋排名?

A: In the majority of cases, it actually doesn't matter ... I try never to rule a signal out completely, but I wouldn't obsess about it. 大部分情形, 這個因素並不太重要 ... 我認為沒有單一因素

從這個回答中, 我們可以知道網域名稱的註冊時間與長短是"其中"一個因素, 只是Matt Cutts認為還有許多因素互相影響...這有點廢話, 不過Matt Cutts並未否認網域名稱的註冊時間與長短的重要性就是了

網域名稱的註冊時間與長短是搜尋引擎最佳化的一個因素
Q: Recently, you removed this suggestion: "Submit your site to relevant directories such as the Open Directory Project and Yahoo!" from your guidelines. Is there any chance that you will be discounting these kinds of links for ranking value in future? 是否將網址送到開放目錄已經不再重要了?

A: There's always the chance that we'll discount directory links in the future...Right now we haven't changed how we're weighting directory links--we've only removed the directory suggestion from the webmaster guidelines. 以後一定會減低這些目錄的重要性, 但目前並未如此做

也就是將網址送到DMOZ等較有公信力的開放目錄還是有效果的
Q: Can you explain how the use of sub-domains helps / hurts a sites ranking? 次網域是否會減損或加強ranking?

A: Good question--do mean in terms of subdomains vs. subdirectories? Maybe we can talk through this one after the official presentations? 沒有正面回答

這個問題被評為好問題, 表示已經觸及了一些重點了, 到底是次網域好?還是子目錄好?哪個可以對於ranking有正面效果呢? 這篇文章"Advice on Subdomains vs. Subdirectories for SEO"可以參考, 以往sub-domain也許可以得到一些效果, 但現在sub-domain與sub-directory似乎已經具備相同效果, 但是有一點值得研究的是site-1.example.com與site-2.example.com到底算同一個site嗎?其ranking的分配與sub-directory如何取捨? 你可以參考以下文章

搜尋引擎最佳化 : subdomain 與 subdirectory
搜尋引擎最佳化 : subdomain OR subdirectory
Q: Since Google is against using ranking software (ie:WebCeO) to monitor SERP rankings, is there any plans on Google creating an approved, in-house rank check application that webmasters can use? Google是否會提供rank check軟體?

A: It's something that we've talked about. My concern is that sometimes people get too worried with paying attention to their "trophy phrase" and want to rank for that even if that's not the best phrase for them, or concentrating on one phrase to the exclusion of all the other stuff they rank for isn't the best idea. I think paying attention to server logs or analytics data gets you a really nice array of keywords that are practical to work on. But this is feedback that we've heard, and personally I think it would be nice if we offered this for some reasonable size of keywords. 回答得好長, 希望不要把重點放在ranking (廢話, 沒Google大家就不會計較ranking啦), 但是重點是可能會提供...以後吧

Google對於PageRank Checker大抵是不鼓勵、不反對, 當然最好的方式是使用Google Toolbar上的PageRank Display, 但因為還要安裝軟體, 所以並不是很方便, 我們提供的PageRank貼紙是一個不錯的選擇

而Google對於SERP的Ranking則是反對的態度, 不過有一些免費工具可以尋找SERP Ranking, 我們整理完後再陸續提供, 其他問題的解析, 我們後續也會繼續探討...

搜尋引擎最佳化 : subdomain OR subdirectory



昨天談到"搜尋引擎最佳化 : subdomain 與 subdirectory", 認為在搜尋引擎最佳化(Search Engine Optimization)的考量下可以使用subdomain / subdirectory, 但是如果只在subdomain / subdirectory下功夫, 而未能整體提升內容等品質的話, 效果可能就不如預期, 許多人會想知道: subdomain / subdirectory其間哪個比較有SEO的效用呢?

如前文所說:

sub-domain(次網域)主要來分別各個不同主機的用途
sub-directory(子目錄)主要來清楚分別各個不同主題的一群內容


對於search engine來說, server1.example.com與server2.example.com是不同主機、完全不同的URL; 而www.example.com/dir1與www.example.com/dir2是同一台主機、同一個URL下的分支

因此在選擇到底應該使用subdomain還是subdirectory時, 應該考量的是: 你可以花多少時間去照顧這個分出去的subdomain或subdirectory?

這是什麼意思呢?

(1)在pagerank不等於零的情況下, 別站連結到你的頁面效果高於自我頁面的連結
(2)在與別站聯結的狀況下, 如果有去有回可能會被判定為reciprocal link
(3)reciprocal link指的是互聯, (Google對於互聯的說法)
(4)某些網站參數的計算下,subdirectory會累積到同個URL, 而subdomain則獨立計算

因此subdomain或subdirectory? 其實是優缺互見的, 完全看你可以花多少時間去照顧這個分出去的subdomain或subdirectory

如果你可以讓某個分支也具有好的pageRank或網頁品質, 並且可以避免成為reciprocal link, 當然subdomain比subdirectory好

但如果你無法花很多時間照顧某個分支, 其實根本不需使用subdomain, subdomain與subdirectory其實是差不多的

就如同許多人曾經討論pixnet把部落格的subdirectory結構改成subdomain, 好像許多部落格站台的SERP表現更好了, 但是你也可能發現並非全面性的, 有些pixnet部落格站台還是沒有起色, 原因就是上面說的, 答案不是yes or no而已, 而是完全看整體的品質

搜尋引擎最佳化 : subdomain 與 subdirectory



正常來說sub-domain(次網域)與sub-directory(子目錄)在網站結構裡應該有非常清楚的用法, 但是問題一牽涉到搜尋引擎最佳化(Search Engine Optimization)問題就變得很複雜了, 為什麼呢? 我們來研究看看...

sub-domain(次網域)主要來分別各個不同主機的用途, 例如

www.example.com 當成網頁伺服器
mail.example.com 當成郵件伺服器
tw.example.com 可當成台灣的網頁伺服器
dns.example.com 當成網域名稱伺服器

但在網際網路廣為運用後, 內容增多了, 伺服器的負荷增加了, 開始了有以下的狀況

product.example.com 當成產品資訊網頁伺服器
question.example.com 當成問題整理資訊網頁伺服器
blog.example.com 當成部落格網頁伺服器
corp.example.com 當成企業郵件伺服器
tw.mail.example.com 可當成台灣的郵件伺服器
tw.dns.example.com 當成台灣的網域名稱伺服器

但是如果再加上為了搜尋引擎最佳化, 可能又變成

search-engine-optimization.example.com 為了取得search engine optimization較好的ranking
marketing.example.com 為了取得marketing較好的ranking

另外更有可能為了盜取他人的廣告效益, 如google.example.com, yahoo.example.com ... 等等, 這些雞鳴狗盜的事情都發生了...

而沒有辦法控制DNS(Domain Name Service Server)的人或快捷的作法也開始在sub-directory下功夫, 如www.example.com/search-engine-optimization/, www.example.com/seo/ ...

sub-directory(子目錄)主要來清楚分別各個不同主題的一群內容, 也就是有一大票的網頁希望可以清楚的區分類別, 但現在有些只有一兩頁的內容也都開始建立子目錄, 為的就是"搜尋引擎最佳化"

甚至更離譜的是許多SEO業者使用sub-domain與sub-directory, 卻都指向內容雷同或完全相同的頁面

這樣的作法有無效果? 答案是目前有效, 但是...指向內容雷同或完全相同的頁面已經可能遭遇悲慘的命運, 而使用sub-domain與sub-directory的效果已經逐漸遞減

sub-domain與sub-directory合理使用是符合簡化網站結構的好方式, 也可以順便進行搜尋引擎最佳化, 但是如果做得太不自然的話, 下場可能會不太妙

TV Viewing Higher Than Ever?



許多專家都在預測, 網路將會取代電視成為新媒體, 就如同之前預測網路會取代傳統印刷一樣, 但最近Nielsen調查美國的收視狀況, 卻有一個出乎意料的結果...

在近期的電視、網路、行動設備使用統計中, 卻意外發現每人平均每月看電視的時間是142小時, 每人平均每月看網路視訊的時間是27小時, 每人平均每月看行動視訊的時間是3小時

看電視的月平均時間比去年增加了5小時, 每人平均每月看錄影電視節目的時間是6小時, 觀看行動視訊的男人比女人多, 觀看網路視訊的女人比男人多...

這些數據當然只是美國觀眾群的平均數, 以每人平均每月看電視的時間142小時來看, 每天約要觀看5個小時的電視, 如果是上班族的話, 大概就是每天下班就窩在電視前面, 才能達到這個數字

以上數據可以肯定的一件事情是: 沒有使用網路的族群的大餅還是比網路族群大, 而網路族群在使用傳統視訊的習慣也未必因網路視訊而快速萎縮

這也就是本網在2002年的文章"當感覺不到網路的存在時,網路的商機才剛要開始", 所說的:

"在網路無法隨時影響您時,這個戰爭不算開始,當感覺不到網路的存在、虛實難辨時,網路的商機才真正要展開,其規模才真正可觀。"

也就是現在似乎很多人都覺得許多網路市場都飽合了, 但是其實還有太多沒有參與網路的消費者, 由於他們無法使用網路或不方便使用網路, 或雖然使用網路但仍然未真正完全參與網路經濟市場, 或者已經參與網路經濟市場, 但仍然大部分透過傳統媒體消費

另外可以看出來的趨勢就是, 傳統媒體不太可能因網路而完全消失, 只是會轉型或合併, 從紙本式的報紙到網路報紙, 現在又可能出現跟傳統紙本類似的電子紙, 就在一個個循環中不斷蛻變, 就好像股票一樣, 永遠都有高檔, 也永遠會有低檔
