Some great stuff if you’re not a natural sys admin or don’t know your way round a robots.txt:

Analyze robots.txt – See whether your robots.txt file blocks specific URLs as is, or with modifications you make. Test against various Google user-agents, too.  This will usually get picked up once a day, and the crawl rule as far as I know is ignored by GoogleBot

Generate robots.txt – Interactively create a robots.txt file to indicate which robots you don’t want crawling your site, and which files or directories you don’t want crawled.

Set geographic target - Associate a particular geographic location with this site if you are targeting users within that area.

Enhanced image search -Enable Google’s enhanced search for images on your site, including advanced labelling techniques for images hosted by Google.
