Page rank droped like crazy, ranked high in yahoo and msn not google

What is going on? I am ranked highly on keywords for my forum in other search engines, but nothing in google, not even the first 200 pages. Also my page rank went from a 6 before vbseo to a 1 on the same page.

I show that you just purchased vBSEO on 11-19, so it's way too early to review any results. For SEO, you have think in terms of months, not days. Just keep your settings consistent, and wait it out.

So is a huge page rank drop expected with the installation of the software?

If your page rank dropped that quickly, it most likely was not a result of vBSEO.

I tend to agree with this opinion myself: PageRank before vBSEO

So what is more likly the issue? I did notice that my site hadn't been indexed since the 22nd for some reason. It was getting indexed alot more often then that.

Do you have vBSEO Sitemap installed and submitting sitemaps to Google and Yahoo?

yea, I have been doing that since before I installed vbseo. I installed the one that was crated by vbseo and listed on vbulletin.org I am currently running a program that will make another one, going to compare them.

Use v1.7 of vBSEO Sitemap if you are running vBulletin 3.6.x and vBSEO 3.0.0. Available in the Downloads area here on vBSEO.com.

do I need the new version of sitemap if I have vbseo's other software? Also I updated the url in the sitemap like 3 days ago. Cause it got changed.

You need v1.7 of vBSEO Sitemap if you are running vBulletin 3.6.x and vBSEO 3.0.0.

What do you mean you "changed the URL"? You changed domain names or forums URL? If so, that would definately affect your PageRank.

I changed the url for google sitemaps because it was getting an error when pinging. As suggested on this page. Google ping: FAILED.

I will install the new 1.7 and see how that works. How fast should I see a change?
