After researching the number one competitor of a keyword I would like to rank highly in, I noticed they had 1,000+ back links from a single domain. They are paying to have their text link on the bottom of every page on this domains website.

I contacted this website and they want $99.00 a month to add my text link to the bottom of every page on their website. They have thousands of pages and a lot of them are high in PR.

So my questions are:

Is it worth $99.00 to have my link on a website like this?

Does it help or hurt SEO since all links come from the same domain?

The number 2 position under this keyword only has a few hundred back links so would it be possible that I would get that position having over a thousand backlinks from this one domain?

I do understand that there is more to SEO than backlinks, but I am just trying to get a feel if this is worth the money or not.

I appreciate any help I can get.
