- If your site had a PR and now has a PR0, you might have been banned. Search for your domainname.com with no www in the toolbar. If you get the "No results could be found... bal bla bla" and no link to your site... bad news.

- If your site's rankings jump a lot, maybe you change the pages and cache is not in sync, there is an update going on, google reverted to old cache... If it just moves a bit up and down... it's only everflux and normal.

- If your site is in a competitive field like real estate, casinos ... this not showing in SERPS is the case of lots of sites. Take on smaller keys until you grow enough to fight.
