Google Webmaster Tools
has a nice tool that allows you to further optimize your top performing pages for better results in the organic listings.
Follow the Navigation in above title on your Google Webmaster Tools account. Webmaster Tools-->Your Site On The Web-->Search Queries-->Top Pages. Scroll down to where it shows the URL's of the top pages for your site.
There will be a graph showing the Statistics for
- Impressions-How many Times those pages showed up for Keyword Queries
- % Change-Shows you up or down the % of change for each Statistic
- Clicks-Shows you how many clicks there were for those queries
- CTR-Click Through Rate-Shows how many click over to that page
- Avg Position-Shows average position of a given page for the queries on the Organic Listings
You will notice a (+ )Box near some of them. Click to expand and see the addition keywords ( Shown Above) that are driving traffic to that page.
You can then take some of those keywords and put them in your:
Meta Tags, Head, Body and Footer to finish your keyword optimization for that page.
I then made a categories and keyword text description bolding
the main keyword or keyphrase for that page and used in the URL towards the bottom of the body section.
Next I took those keywords and made backlinks from blogs,forums and Social Networks and started a mini link building strategy I always use.
If you have a product or service you need conversions on, then I would suggest putting "Buy Now" in the Link URL or in the Code In Context and if you have a Local Business put in a map to your store location using Google Maps
In closing; webmaster tools has allot of features you can use to properly optimize using their tools, its just a matter of taking those tools and further analyzing their results for better analytics which in return helps you to better optimize each page for higher organic listings in the SERP'S.
