How can a site not indexed on google still have 40+ Page Authority on OpenSiteExplorer?

[MH-Seonoob]

Hey guys,

I was revisiting the backlinks to my site and found a few that were not indexed on Google anymore. I confirmed this by typing site:"SiteAddress" in google and it retuned 0 result. Yet when i searched the same site on OSE (OpenSiteExplorer) yielded me a PA of over 40.

I used to research sites on OSE to see if they are worth pursuing for a backlink but i am second guessing this because of this recent finding. Can someone please shed some light on this?

Thanks!

<address>The site may be no-indexed (via no-index tag or various other ways accidentally) or penalised, have you investigated either possibilty?</address>

A few things to investigate:

Did you try the site: command? Your post says 'siteaddress:' - I don't know what that is.

What date did this occur?

Have you tried the Fetch as Goole tool in Google Webmaster tools?

Checked for crawl errors in GWT?

Submitted an XML sitemap to Webmaster Tools?

Is Bing indexing it?

Site No indexed in Google has nothing to do with DA or PA of the website as these are the parameters by SEOmoz which are purely based on the number of links a website have!

No index from Google doesn’t means website can’t have links coming from other websites.. so, if there are external links pointing to the website there will be a PA and DA of the website and page.

Hey David,

The site is definatetely not no-indexed. I am worried that it may have been penalized by google though which is why i was wonder why it still had a decent PA.

It is the site: command that i tried and indeed it did not return any results. I could not fetch as google as it is not my site. It's just a site that i had an incoming backlink from.

And yes it is indexed in Bing.

Hey Moosa,

I was using DA or PA stats to analyze if a site was worthy to pursue for a backlink. If you are saying that a site that has been de-indexed from the G man can still have high DA or PA then how do i go about finding out if this is a quality site in google's eye then.

DA and PA only tells you about how many links a website have but for quality of website probably you have to manually look in to the link profile and analyze each website on basis of their quality and how they are linking back to the website.
