How I am testing backlinks 

Alot is being talked about when it comes to backlinks in SEO circles. Basically, they are the holy grail of the Internet. It's not the amount of them nor is it the link architecture methodology. It comes down to the quality of your link. Is it an ad? or is it information? Search engines like information as ads are usually looked at as spam and they want to provide their users with the best quality sites according to the user's search criteria.

What also matters is where the link is either coming from or going to. If  you link to a Page Rank 6 or 7 page, it actually improves your ranking as well. If a Page Rank 6 or 7 links to you, then  your page gets a higher value Page Rank.

What's an SEO?

Why does SEs hate SEO companies?

SEO is an abbreviation for "search engine optimizer" or "seach enging optimization." Many SEOs, agencies and consultants provide valuable services for websites and their owners, from writing copy, giving advice on site architecture to helping find relevant directories in which their site should be submitted. On the other hand, there are also unethical SEOs which have given the industry a bad name through overly aggressive marketing efforts and utilzing techniques which attempt to unfairly manipulate search engine results in their favor.
