Linkbuilding with blog comments
An interesting article on Search Engine Journal (www.searchenginejournal.com) today.
Most people think of comment spam when we’re talking about links from weblogs.
But by leaving 3 relevant replies every day you can build almost 100 links per month.
Off course lots of them will be no-follow links, but that feature is ignored by humans, so it can bring significant, relevant traffic to your site.
Take your time, you’re reading the relevant blogs anyway. Share the knowledge you have and direct valuable traffic to your own site at the same time.
And remember: deeplinks
