Search engine patents deals - Changes to Come

It's 100% that changes on your web pages influence the position of your website on search engines.

However, it's not so clear how search engines react to the changes on your site and what exactly causes the changes in the search results. A new search engine patent might have some answers.

Several search engine patents deal with the changes on your site
Google published a patent that described how the changes on your web pages influence the rankings of your site 6 years ago. Last month, Microsoft was granted another patent that discusses the influence of web page changes on search engine rankings.
This new patent shows which elements on your web pages might be monitored by search engines.
Which web page elements are monitored by search engines?
According to the new patent, changes of the following web page elements can influence the position of the page in the search results:
  • Keywords that are included in a web page.
  • Keywords that are associated with a web page
  • The anchor texts that are used in links on the page.
  • The colors and the sizes of images on the page.
  • The position of text or images on the page.
  • The frequency of document changes over time.
  • The amount of the web page content that has been changed.
  • Tags that are assigned to the page.
  • Search queries that are used to find the page.
How exactly do changes in these elements influence the rankings of a page?
According to the patent, searches are classified into the two categories "informational" and "navigational". The effect of the web page changes depends on the category of a search query.
A navigational query is a query that is used to find a particular site. For example, a search for "ny times" will lead to the home page of the sites. Examples for information queries are "how do I fix a broken bicycle tire" or "who won the 2011 XYZ awards"?
If the searcher is looking for information about a recent event (2011 XYZ awards) then pages that recently added the keyword could be boosted in the search results.
For navigational queries, pages with static content might get a boost. This methods works fine with some type of sites but it could cause problems with home pages that update their contents regularly (for example nytimes.com).
What does this mean to your website?
This patent was granted to Microsoft but it's likely that Google uses similar methods. Search engines don't just look at the current version of your website.
They also remember how it was in the past. The changes on your website could indicate a change of ownership, they could indicate that you try to keep your website up-to-date, they could be a signal for spam and more.
When you change your web pages, consider which signal you might be sending to search engines.
When you optimize the pages of your website, do not optimize a page that already has high rankings for one of your keywords. Better optimize another page of your site for the new keyword.
