If i sell link on my homepage, any harm to my site regarding alexa or pr? does sellling front page link differ from link that duplicates throughout the site? anything else i should know about selling link?
what is an seo link? someone emailed my site to do an seo link in the main page and the link doesn't even have to be big and visible, they just want to have their link on my front page. would it produce a negative effect on my site?
I think Google may place some kind of penalty on your website if they find you involved in any kind of link selling activities
what about those site with "friend" links in the front page? i have seen a lot of those. do they really get penalized?
Yes a link could have an effect on keyword performance and the position of your website on major search engines including Google. Links are SEO go hand-in-hand..... It could hurt your site, and help the site or sites that are linked. It could also help both websites or hurt both sites. Many factors come into play including how the link is linked, the number and type of other links on your site and other internal links that are on your page. If you would like to give a better example, I would be happy to offer advice based on your website and his website.
If links are relevant to your site then I don't think that selling such links would have any harmful effect on your site's ranking. But you should take great care while selling links on your site.
