SERP or ‘Search Engine Results Page‘ is simply the search-results page that is returned to a user when s/he searches something on the Internet (Google/Yahoo etc.), and that “something” is the “keyword” or the “key phrase”.

The position of your website/webpage on the search-results page is very important in bringing quality and converting traffic to your site, so SERPs ranking is now an important part of SEO.As there are number of
SERP-tools available on the Internet,finding the BEST-SERP tool is quite a difficult task.But,as this tool belongs to Search Engine Giant :Google,it makes a lot easier.

If you are registered at Google-Webmaster-Tools, then simply log in to it, and go to the recently updated “Top Search Queries” section of the website (under “Your site on the web”). In this section, now you can see the number of impressions given by various keywords/phrases and how many of these impressions got converted to visits (click through).

Google has made it easy to filter the results,Instead of the data from all the countries, you can select a single country from the top drop-down menu.By simply clicking on a specific keyword/phrase you can see the details, like in which position how many impressions got converted to visits.
Three simple strategies to improve your ranking on SERPs for the popular keywords/phrases are;
(1) Write more articles on that topic.
(2) Try to use that specific word/phrase in the titles of your articles.
(3) Include the most popular keywords/phrases (receiving maximum impressions and not necessarily having a high value of click through) in your meta description and keywords tags.
