Google has made ten recent algorithm changes


We are continuing the series of posts in the blog Google Inside Search, revealing the features of Google search algorithms, as well as detailing all the modifications thereto, the Corporation’s Lead Engineer, Matt Cutts posted on the official Google Blog the latest 10 changes made to the ranking system, which became effective over the past couple weeks:

1. Cross-language information retrieval updates: For queries in languages where limited web content is available (Afrikaans, Malay, Slovak, Swahili, Hindi, Norwegian, Serbian, Catalan, Maltese, Macedonian, Albanian, Slovenian, Welsh, Icelandic), Google will now translate relevant English web pages and display the translated titles directly below the English titles in the search results. This feature was available previously in Korean, but only at the bottom of the page. Clicking on the translated titles will take you to pages translated from English into the query language.

2. Snippets with more page content and less header/menu content: Previously the snippets that appear in search results contained a high amount of content retrieved from the header or the menu of a webpage. Now the algorithm is that little bit smarter, and will begin to pull more of the snippet from the content of the page body text.

3. Better page titles in search results by de-duplicating boilerplate anchors: Google looks at a number of signals when generating a page’s title. One signal is the anchor text in links pointing to the page. Google found that boilerplate links with duplicated anchor text are not as relevant, so Google is putting less emphasis on these. According to Matt Cutts, the result is more relevant titles that are specific to the page’s content.

4. Length-based autocomplete predictions in Russian: This improvement reduces the number of long, sometimes arbitrary query predictions in Russian.

5. Extending application rich snippets: Original snippets were text only in format. This enables people who are searching for software applications to see details, like cost and user reviews, within their search results. This change extends the coverage of application rich snippets, so they will be available more often.

6. Retiring a signal in Image search: As the web evolves, Google often revisit signals that it launched in the past that no longer appear to have a significant impact. In this case, Accordong to the Lead Engineer, Matt Cutts, Google decided to retire a signal in Image Search related to images that had references from multiple documents on the web.

7. Fresher, more recent results: As It was announced just over a week ago, Google made a significant improvement to rank fresh content. This change impacts roughly 35 percent of total searches and better determines the appropriate level of freshness for a given query.

8. Refining official page detection: Google tries hard to give the users the most relevant and authoritative results. In an attempt to quash wannabe’s taking search results and from official websites, this adaptation of the algorithm attempts to restore genuine content from official sources higher in the results.

9. Improvements to date-restricted queries: Google changed how it handles result freshness for queries where a user has chosen a specific date range. This helps ensure that users get the results that are most relevant for the date range that they specify.

10. Prediction fix for IME queries: This change improves how Autocomplete handles IME queries (queries which contain non-Latin characters). Autocomplete was previously storing the intermediate keystrokes needed to type each character, which would sometimes result in gibberish predictions for some languages.

In addition, Matt Cutts asks to remember that this is only a sampling of the hundreds of changes Google makes to search algorithms in a given year.
