Google changes: Ten recent algorithm changes

If your site got downgraded by Google in the last couple of days, the announcement below is probably the reason why.

The most important ones for SEO are these five changes in Google's algorithm:

  • Snippets with more page content and less header/menu content: This change helps us choose more relevant text to use in snippets. As we improve our understanding of web page structure, we are now more likely to pick text from the actual page content, and less likely to use text that is part of a header or menu.
  • Better page titles in search results by de-duplicating boilerplate anchors: We look at a number of signals when generating a page’s title. One signal is the anchor text in links pointing to the page. We found that boilerplate links with duplicated anchor text are not as relevant, so we are putting less emphasis on these. The result is more relevant titles that are specific to the page’s content.
  • Fresher, more recent resultsAs we announced just over a week ago, we’ve made a significant improvement to how we rank fresh content. This change impacts roughly 35 percent of total searches (around 6-10% of search results to a noticeable degree) and better determines the appropriate level of freshness for a given query.
  • Refining official page detection: We try hard to give our users the most relevant and authoritative results. With this change, we adjusted how we attempt to determine which pages are official. This will tend to rank official websites even higher in our ranking.
  • Retiring a signal in Image search: As the web evolves, we often revisit signals that we launched in the past that no longer appear to have a significant impact. In this case, we decided to retire a signal in Image Search related to images that had references from multiple documents on the web.
The last two are rather vague, but the first three are quite clear: less consideration to Title tags, Headers, menu items and much more consideration to the actual copy/text on the page, so less emphasis on hieararchy - which will make SEO even harder..

This seemed to have affected my website design Ottawa site but has not had any impact to my SEO Ottawa site.
