Google Analytics makes our lives easier. Easy installation, intuitive (usually) reporting/metrics, easy integration with Adwords and Webmaster Tools, etc. Best of all, it’s free. Of course, installation is also easy to botch, and future installations don’t always correctly overwrite the old ones . You may have failed to add the tracking code to certain pages. Or perhaps you have multiple implementations on certain pages. Maybe certain pages have your old Google Analytics tracking code. Perhaps you have 2,3 or even 50 websites sharing a code base and you ended up getting your wires crossed. This can really skew your metrics in numerous ways.

I have been using this nifty tool for a lot of on-site optimization lately. You can use it to crawl your site and find broken links and redirects, link juice flow, last date modified, review meta and H tags, etc. It’s also useful for checking for instances of specific code implementation. Out of the box, A1 WSA can check for gat and gaq object methods for Google Analytics tracking code as well as Google Adsense tracking. This is useful for searching for pages that lack this code (or pages where the code has been been implemented more than one).
