Why does this site deserve a PR5 ranking?

I was researching sites for a client and stumbled upon this site and am trying to figure out why it has a PR5 ranking. It's backlinks are a little sparse and the links it has are not all that powerful. The title tag is not very descriptive, no META tags or description (I know these do not affect PR, but I was looking at the site as a whole for SEO and it comes up short). If anyone has any ideas I would love to hear them...

The site is www.zeavision.com

 

In my opinion its near high PR4 or low PR5

backinkwatch report shows the fact

 

I dont see it holding that rank very long

 

Will the rank go down as well?

 

check some redirect from other sites, maybe you can find the gem there

 

Some vital and relevant links might contribute to more than 50% of it's pagerank value , and I can tell you that only G know.

Very interesting ,I have found one link from .edu site just this morning from g webmaster tools. It's make my serps up dramatically over a week now!
Thanks and hope it will contribute to my next PR also.

 

which tool did you use to check its backlinks?

if you have used google, it's not showing all of the backlinks

 

yeah, try looking backlinks from yahoo because it shows all your backlinks.

 

if you tried to list your site on google webmaster tools or even using it, you will see you backlinks pointing to your sites.

 

First thing first--

PR depends on quality of the links --not the number.

Second thing -- PR has nothing to do with SEO parametres. Its all about inbound links.

Third -- Google PR algo is changing-- I think most alert guys who deals in PR and not SERPs know this.

There was a time when webmasters could have a rough estimate of how many links of what PR/quality is required to reach a certain PR. But that day is gone --Google is certainly discounting VOTING VALUE of a lot of links.

This site shows it has just --1 PR6 inbound link-- few PR4 link --and its PR5. It certainly what I am talking about.

I had a PR3 site --and got lots of PR5, some PR6 and 3/4 PR7 links. According to old estimate it was supposed to have PR6.
But NO--Google gave me just PR4.

So --people who are still in the old mood of counting these many links for this PR--are surely going to loose.

Just my 2 paisa.

 

This is all great info everyone, thanks! As to those that asked what tool I used to check the backlinks - I used SEO Spyglass with Yahoo as the search engine. VERY DETAILED info on all backlinks.

I understand that it is not the quantity of links that helps to determines PR and that it relies more on the quality of those links (not that PR is completely decided based on backlinks, but it is a big factor), it was just that this site did not have much of either. In addition, it did not seem to be that old and/or, optimized or content rich, so I just could not understand how it achieved a PR5 - not that PR5 is the world and equates to actual traffic, it is just an interesting value given by Google.

 

True. SEO SpyGlass is one of the few SEO tools worth paying for. I'm yet to find a tool that pulls this much data from the SEs, and is this easy to use. You get very detailed backlink reports on any site -- backlinks, anchors, titles, site age, link value, PageRank, Alexa, etc. etc. Very handy in researching competition and figuring out how to beat them.
