Hi!
All you said before are a few items offered by tools that test a site's popularity. I just found a great tool at marketleap with a keyword verification, Search Engine Saturation, Link Popularity Check and Keyword Discovery. Let's take step by step and see how every feature work.
The keyword verification checks the first three pages of important SE's for a specific keyword to see if your site is there. They check only 3 first pages because most users look usually only at first pages.
The Search Engine Saturation says how many pages of your website are indexed at a SE. You can compare that number with other competitor's sites and make some predictions.
The Link Popularity feature is used by most users; this lets you know who has a link to your site and also you can check the history of your site about backlins.
The new of all is Keyword Discovery, helps you to find out what keyword brings visitors to your site, or produces. You also can do the same researches for competitor's sites.
That's it, i hope you make an opinion about it.

Ok..
But we can also do SEO manually.


Thank you,
