Google Algorithm

December 28, 2007 By: Sergey Rusak Category: Search Engines

Many experts was trying to explain of what the Google Algorithm formula might look like. Some of them came with very close ideas but it was still just thoughts, guesses, theory with lack of evidence.

I just wanted to know where you’re getting this info. Have you made any real case-studies that this is actually the way it works?

I understand that a these questions might come off as jerkish, but I’m actually serious, not really trying to come across as obnoxious. I just want to know! I want to rank well! And so far, all other info has proven false!

Thanks for any help!
Bryan

Right from Google HQ
Just Kidding.

I work with many clients and I read a lot of blogs and forum discussions. Also, I read Google official blog as well where you can find a lot of information.

So, my Google PR explanation based on my experience (including results of my clients).

When you talk about Unlimited link exchange (reciprocal linking), could you expand on this subject a little because it used to be the way to get higher rankings. Now, that it may be different, should us webmasters be cleaning up our link pages? Will it help us rank higher if we do clean them up?

Also when you talk about anchor spamming, what is considered anchor spamming?

Anchor spamming is when you are trying to rank well for specific keyword and got 100-300-500… backlinks with the same anchor overnight. Google consider it as keyword spam.

About receprocal links… you should clean all your broken links and links which lead to bad websites (adult, hack, porn, parked domains, affiliate made).
