Adding links will help my SEO?

[imisidro]

Not really since it will be you giving the other site some brownie points for linking to them. If they are the ones linking to you, then you can actually see an improvement in your pagerank and hopefully your search results ranking

But be VERY CAREFUL -- link ONLY to sites related to you. Google will not want to see your plumbing service site linking to a mortgage company just because it is a local company in your area. Google in particular has penalized sites linking indiscriminately to sites outside their topic area. Limit your links to sites with similar and related topics

Your gauge should always be: will adding these links be beneficial to my users? SEO should only be second consideration
