All the pages have been de-indexed already! What can I do?

I don't know why, but for some reason my website pages (ugandaguide.biz) have been completely de-indexed by Google. The second thing is that when I googled my site a few weeks ago, it came under other URLs which are not in any way associated with me. It is as if they attached themselves on my site.

Can anyone advise me on what to do. I really had a very good page rank but I am not at 0!

I swear I have not done any updates on that site for almost 8 months. I had a very good ranking and people we approaching me to add their sites on mine but I refused those offers, is there a slight possibility that someone could have maliciously attacked my site so as to be penalized by Google?

Thank you very much

I have checked your site, anyway I am not sure what caused this matter, but at least, I don't think it is hacking.

Please look at your code:
<meta HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<meta HTTP-EQUIV="Pragma" CONTENT="no-cache">

Mayby this works? I am still not sure.

you may have lost inbound links

Thank you Tiffany Hua. Are you suggesting I consider adding

<meta HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<meta HTTP-EQUIV="Pragma" CONTENT="no-cache">

to all pages?

One thing that led me to suggest that my site could have been attacked was someone who noticed the de-indexing in the beginning mentioned that the reason for de-indexing some of the pages was given as "SPAM" I have no idea what that meant and I could not believe that it could happen. How can I tell if my site has been hacked?

Thank you for your advice.

I went and did a link check on Host and IP addresses Backlink Checker [online-utility.org/webmaster/backlink_host_ip_analyzer.jsp] for ugandaguide.biz and I found out that most of the domains appearing in this report are STRANGE and I have nothing to do with them. How did they link to my site? Is this some form of hacking?

No I am not suggesting adding the codes. I am suggesting to remove them.

I am not sure if this is necessary, please someone else could help confirm?

A no-cache is probably what is affecting your ranking. Once that is in the code it tells google that when they come back not to save a copy in their database. If no copy is saved in their database you cannot be searched.
I think Tiffany is saying that this code is currently on your site and it is bad.

I will take it out and see how that will go, thanks a lot guys!

It appears the site has been banned by GOogle. This is the time when one actually needs to invest in the skills of a competent SEO. Remove the cache robots tags and hope that it returns in 2-4 weeks. If nothing, it's a bigger problem. Without spending more time and also time looking at the behind the scenes/history that's all I can really say.

ps. looking at yahoo's thoughts on your web site it appears you were using a chatroom at some point that was running amok with spam, that probably has somethign to do with it.
