Google May Day Algorithm Change
A major change in Google search algorithm took place in May 2010. The algorithm has been tweaked for long tail queries such that higher quality sites appear in SERP.
Individual long tail queries would not provide much traffic, but in aggregate can provide a significant amount of traffic. Large sites with product pages that would not have individual links into them, be several clicks from the home page or be hidden behind search forms (dynamic pages), and may not have unique and value-added content on them would be impacted. Smaller sites with good or even better unique content, but with few incoming links, and attracting little traffic should be benefited. If your site has been negatively impacted by ‘Mayday’ change, you need to do an analysis to make these pages more valuable to search engines. For pages where you notice a sudden drop in rankings after May, you can analyze sites which are now ranking on top for the targeted keywords. Optimize content with long tail keywords, more relevant and current information, and minimize duplicate content pages.
Google Instant
Google announced Google Instant on September 8, 2010 in the official Google blog. “Google Instant” helps you find relevant pages even as you are typing search query. Based on what you have typed, even before you hit ‘search’ button, it predicts the most likely completion and streams results in real-time for those predictions.
Core features in Google Instant:

  1. Dynamic Results – Google dynamically displays relevant search results as you type so you can quickly click through to the web content you need.
  2. Predictions – prediction of the rest of your query appears in light gray text in drop down box as you are typing. If you find a predicted search term is what you were looking for, simply stop typing and view the dynamic results displayed and click on what you’re looking for.
  3. Scroll to search – Scroll through predictions and see results instantly for each as you scroll down the list.

Site owners may notice an increase in impressions because your site will appear in search results as users type. After roll out of Google Instant, impressions are counted in following instances :

  • The old method : site is displayed in search results as a response to a user’s completed query (e.g. by pressing “enter” or selecting a term from auto-complete options
  • The user begins to type a term on Google and clicks on a link on the page, such as a search result
  • The user stops typing for a minimum of 3 seconds, and the results are displayed

Google Instant will push sites to focus more on keyword research and a keyword and content strategy. On-page SEO elements supporting relevance will have positive impact.
Google Instant, because of its tendency to collapse the long tail into a smaller set of shorter tail key words. Sites will have to keep tab of duplicate content and use rel=canonical tag to indicate to search engine the preferred page for indexing.
Pagination is any kind of control system that lets the user browse through pages of search results, archives, or any other kind of continued content . Pagination is a huge problem for search engines. For Google or Yahoo!’s search results, pagination is a big issue because while search engines want to give exactly what you search for in the first 10 or 20 results, there times when search results will display consecutive pages. The recommended solution is to provide a default view with all of the products/articles/pages on a page, and use rel=canonical tag for the paginated versions to indicate the default page as the canonical or preferred page.
If your site has identical or vastly similar content that’s accessible through multiple URLs, this format provides you with more control over the URL returned in search results. It also helps to make sure that properties such as link juice are consolidated to your preferred version. You can now add rel=canonical tag inside the <head> section of the duplicate content URLs to specify your preferred version:
<link rel=”canonical” href=” ” />
