1. Do "Chained" 301 Redirects Not Carry Link Popularity Over in Google? - 2007-07-09 08:29:33-04
   

   A WebmasterWorld thread discusses the implementation of 301 redirects on a newly constructed site.

   WebmasterWorld administrator, Tedster, adds to the discussion that he has seen that a chain of 301 redirects does not always pass the link popularity along.

   For example, you have URL1 that is redirected to URL2 and then have URL2 redirected to URL3. In this case, Tedster seems to imply that URL1 will not pass link popularity over to URL3. It will not carry over from URL1 to URL2 to URL3.

   Instead it seems that if you need to set up a third redirect, you should change the original redirect from URL1 to URL2 to URL1 to URL3 directly. This way there is a direct redirect from one URL to an other, without having to go through multiple chains of redirects.

2. Google.com Has Multiple Cache Pages & Snippet Archives - 2007-07-09 08:37:14-04
   

   A WebmasterWorld thread has two claims from respected members, giving us a little more insight into Google's search engine.

   The first thing we learn is that Google has several cache databases.

   When doing site search "site:exmple.com" when I see the snippet description of the page xyz.html and compared it with "site:example.com/xyz.html" they were different in fact the later consists many months previous page. To verify this I compared the Google's cached pages those were also different.

   Tedster, WebmasterWorld administrator, confirmed this to be true. Is it simply a data center thing?

   Respected member, g1smd, added that often the snippet Google chooses is not pulled from the cache. He said that Google has a snippet database that is typically much older than what is found in the cache.

   The snippet database often contains content that hasn't been on the site for many weeks or months, content that is no longer in the Google cache copy either. It has all that, as well as content that is current.

   Note, none of this has been confirmed by Google.

3. Details of Google AdWords Quality Score Via Patent Applications - 2007-07-09 10:07:44-04
   

   Bill Slawski, resident patent guru, has discovered yet another patent application about Google AdWords . The discussion has been brought to the attention of the folks at WebmasterWorld . According to Bill, there are 44 factors in total that might be used in a Google AdWords quality score. Some of these include:

   • How many times a user selects a given ad in a given session.
   • A duration of time, from an ad result selection, until the user issues another search query.
   • A ratio of the time, from a given ad result selection until the user issues another search query, as compared to all other times from ad result selections until the user issued another search query.
   • Time spent, given an ad result selection, on viewing other results for the search query, but not on the given ad result.
   • How many searches (i.e., a unique issued search query) that occur in a given session prior to a given search result or ad selection.
   • How many searches that occur in a given session after a given search result or ad selection.

   This information seems to apply only to Google AdWords, but the descriptions are pretty clear and many are happy to have stumbled upon Bill's post because they now have a greater understanding of the Google AdWords quality scores.
