Describing it a zerg rush of launches that it had, Google has just listed some of the major changes effected by it in the recent times, including  its most recent algorithm improvement so as to help user reach more quality websites. And there is much more that the search engine giant has been up to like changes done in indexing, sitelinks, spelling and sports scores features. Here is a quick look the updated search quality highlights’ list:

• Categorize paginated documents: Search results sometimes can be dominated by a paginated series documents. This change will help surface in such cases more diverse results.
• Navigational results that are more language-relevant: When the user for navigational searches keys in a web address, the engine usually tries to rank that address right at the top, but this isn’t necessarily the best answer. For instance, though is bol.com, a Dutch page, many users are searching actually in Portuguese. They are looking for bol.uol.com.br/, the Brazilian email service. The change will take into account language.
• Country identification for pages: Location is a key signal used for surfacing content relevant to a country. For a while, Google had systems to detect when a site, subdomain, or directory was relevant to a specific set of countries. The change will extend those systems’ granularity to the page level for websites, which host user generated content.
• More domain diversity and anchors bug fix: The latter fixes a bug related to handling of anchors. Search at times returns too many results from similar domain. More domain diversity will help surface content from a large number of domains.
• More local websites from organizations and local navigational search Improvements: The former makes it much more likely users to find an organization site from their home country (for example, mexico.cnn.com rather than cnn.com for Mexico). For searches including location terms, Google more likely ranks the local navigational homepages in higher position, even where the navigational page doesn’t make mention of the location.
• Improvements to search term scoring in ranking: A fundamental signal employed in search is whether or how search terms surface on the webpages users are searching. This change will improve the way those key terms are scored.
• Disable salience in snippets and more text from the start of the page in them: This particular change updates Google system to generate snippets and keep it consistent with other major infrastructure improvements. It increases consistency in the overall snippet generation process. The later makes it far more likely Google will display text from the start of a page in snippets especially when that text happens to be particularly relevant.
• Smoother ranking changes for fresh search results. As Google explains, it wants to help people get the best and latest results, for searches with key new web content particular like news topics. The engine tries to promote content, which is apparently fresh. This change will apply a more granular classifier, resulting in more nuanced alterations in ranking on basis of freshness.

As part of spelling model refresh plus quality improvements, changes have been made in 27 languages.
