Try this query to find pages that are in Google's supplemental index (trick invented by [Bruce Clay, Inc](http://www.bruceclay.com/blog/archives/2007/08/google_hack_fin.html)):
```
-site:aktagon.com/* +site:aktagon.com/
```
The query should list all of your pages that are in [Google's supplemental index](http://en.wikipedia.org/wiki/Supplemental_Result) a.k.a [Google hell](http://www.seomoz.org/blog/how-i-escaped-googles-supplemental-hell). These pages lower your Google page rank, so you should tell Google not to bother indexing those pages. This can be done with [robots.txt](http://en.wikipedia.org/wiki/Robots.txt):
```
User-agent:*
Disallow: /tags/*
Disallow: /archive/*
```
Another way of doing it is to add a meta tag:
```
```
This tells search engines to read the page but not index it.
And, be careful with what you put in robots.txt...
