How to Promote Your Website with DoFollow Blogs by:Michael Swengel
In the early days of blogging, any link in comments on a blog post would be indexed
and followed by the search engines - giving the sites being linked to a search engine ranking boost.
Unfortunately, this led to a huge amount of SPAM and nasty comments being posted.
So came the NOFOLLOW tag for blogs. A site that uses NOFOLLOW tells search engines "don't look at links in comments on this blog."
The negative side of NOFOLLOW is that legitimate comments don't get recognition from Google or other search engines.
To counteract this is the DOFollow movement. DoFollow isn't a tag - rather it is the absence of NOFOLLOW. Approved DoFollow blog comments get indexed by search engines and commenters' websites get the promotion they deserve.
If done right, this can be a grand way to get links to your website.
Look up DoFollow blogs that interest you and are relevant to your website.
Choose a blog or blogs that are relevant to your website. If your website is about computers, visit computer blogs. If your site is about health, comment on health blogs.
Google and the other major search engines love this. They will see one-way links coming from websites in your category and boost your search ranking.
Google especially loves one-way links. That means a website links to your site, but your site doesn't link back.
The category is important. If your site is about health, Google needs to know that by seeing links from other health sites pointing to your site. This helps to put your site into a specific category so it will rank better in searches.
