Are data on SAPE even accurate?

I am just curious how accurate are data on SAPE? For example, I see a hell lot of high PR links I can purchase, but when I check the backlinks of those sites, they barely have any backlinks at all. I found 1-2 urls that SAPE considered INDEXED on Google, but they aren't.

As we all know SAPE is just a platform for buy/rent links. So the owner of the site can blackhat their site to PR5 and rent it for more money.

Do you guys even double-check the actual PR before purchasing? Thanks.

Always check if the website have a healthy backlink profile, otherwise don't buy from it. Find a decent provider, or do it yourself.

You need to do some extra work to ensure that you are buying the best of links.

There are different things to look out for when selecting a possible link. Send me a PM if you want and I can help ya out a bit.

Some of the info on sape is indeed inaccurate and it's always been like this, they do actually run their own clean up updates every now and then to weed out the bad stuff, but the best way to be 100% sure is to set your links to semi-auto or completely manual if you cannot setup proper filters in sape for semi-auto, that way you can then run your own third party PR and also indexing checks on a list of links before approving them to go live.

What your seeing there too could also be a well known trick to manipulate PR, I will not go into specifics here for obvious reasons but these networks can be full of them, as rasmusk said check for incoming links etc before hand, legit PR sites are pretty easy to tell.

I'd suggest installing Majestic SEO Backlink Analyzer on Chrome, and doing a site:.com or info:domain.com to make sure it's indexed and the PR is real.
