If it was in self improvement and personal development it might have some, but if it was a health and fitness site of course it would have a lot of relevance and hence value. Too many wrong backlinks can result in a form of a Google slap where your site is un-indexed
Also investigate whether the site you link with is Nofollow or Dofollow. A backlink from Nofollow link will never bring any value in term of SEO effort because the search engine spiders will not follow the link back to your site, though of course you may get traffic from that link if visitors to that site clicked your link.
Returning to the question of how to get backlinks of high quality there are a number of free ways of doing this. Paying may be an enticing option, but there are dangers and it is better to outsource the more effective tasks rather than paying for cheap backlinks of no value.
A quality content link will result in positive results in SEO and traffic. However, a link must have certain qualities to be considered an effective one. The site you are linking from should itself have quality content ie be an authority site.
The first place to start is obviously now the social media sites (what did we do before them?) Whilst it does take a little time to get setup on forums and blog sites etc, the investment is clear to see below.
How To Get Backlinks Without Spending Money
Social Media: Twitter and Facebook
Adding an update which includes a link to a profile or product page etc is easy. The same works for Twitter, leaving a quick message and adding a link is really quick and easy. You can also use a tool like Tweet Adder to set up automated tweets throughout the day, so you are setting up multiple backlinks.
Social Bookmarking: Digg, Stumble and Tumble
Social bookmarking and blogging can be a very powerful tool because the search engine are always crawling them for new and popular content. I’ve found that Digg, Stumbleupon and Tumblr are great networks to submit to..
Posting on Forums
Find a forum that is relevant to your niche. Sign up and start making comments. Be careful not to spam, but leave helpful comments and answer questions, which can lead to sharing your link. Connecting with like minded business owners and people interested in your products can also lead to other activities like JVs. Usually a forum will allow you a link in your signature that people can click on to find out about you – ie generate traffic as well as back links
Comment on Blogs
Just as with forum posts, finding a high traffic blog will do the same. Leave a comment that is useful for the reader. Don’t just write “great post”, these won’t get approved, write something useful and helpful!
An authority link is a backlink from a site already trusted by Google in terms of trust rank. It’s a factor of Google Algorithm, in which once a web site is detected to be an authority, it will get more visibility in SERP’s on related.
