Bloggers hoping to rank highly in search engines have to be wary if they leave comments open on their site.
Spam is an age-old internet problem, and search engine spiders can pick up on bad links in comment boxes if the default rel tag, dofollow, is enabled on your blog.
By using the nofollow tag, you can ensure that search engines won’t downrank you because someone’s posted something disreputable on your blog. It’s a great tool for boosting your search engine optimisation – and you can still benefit from genuine backlinks.
Many people aren’t aware of the default dofollow option, so it’s worth thinking about changing it to nofollow if your page is suffering from spam.
