suddenly i lost my rank in google

[sakherq]

using Google Analytics i found that visits from Google to my web site decreased in scary way since 10 days .
iam running a forum which is built by me from a to z similar to VBulletin
i wrote a page called "post.php" to show threads in the forum with title derived from a database with meta-tags , this page used to get listed in google results to bring visitors to the web site , i change the thread title always when i find that editing title will help in SEO , could it be that Google considered changing page title is illegal way to get better ranks for threads so Google stopped showing post.php in search results ??

Hold on did u ever think of stealing content.In that case I guess your IP address
has been banned by Google and your website has been termed as a PLR website (plagiarized).Other wise it could be that you haven't adjusted your meta tags properly and have failed to ad fresh content to your site and hence the spiders didn't crawl your site.That could be one main reason for your SERP'S to go down.

there is a page called forums.php that provide links to threads threads can be viewed in a page called post.php ,, google shows results from my web site but does not guide people to post.php directly ,, google only show forums.php in the results . this thing happened one day when i saw that visits from google decreased to 50% ,, that moment the search engine decided to view results from my site in the 3rd or 4th page of search results

Yes Google algorithm is unpredictable...
You may never know what happen during the minor updates...We don't see the changes. That's why.

What hold true for google today can vanish another day ,that's the way google is. Get used to its moody nature.

Google surely doesnt like when you make BULK changes, especially to your TITLE.

I did tried changing TITLES for some of the websites, but it was of no use. Finally I made it a point to stick with ONE TITLE throughout my LIFE ;)

Moreover, you should make sure that your users are not posting content from other websites. This could lower your rankings on search engines.:confused:
