There are thousands of blog directories around these days so when submitting your blog you need to play it smart.
If you are submitting purelyfor link value then high ranking blog directories that utilize the ‘dofollow’ are a must. If you are looking for traffic then perhaps using the lower ranked blog directories could offer better value.
With the higher ranked blog directories, you are competing against ten’s of thousands of blogs. In any one day there may be 1000 new submissions. With so much competition your chances of being seen and your link followed are greatly reduced.
The smaller blog directories have fewer blogs listed so your chances of being on the first couple of pages for your category. This increases your visibility and with it the chances of having your link followed.
There is a downside to submitting to smaller directories and that is the substantially smaller flow of traffic. However being seen by a few can be better than being hidden from the masses. If you are selctive with your choice of directories and try to find directories with specific categories related to your site then your hit rate may improve further.
Ideally, you should submit your blog to a variety of different blog directories. Some large with good rankings and some small with low rankings but the opportunity for good exposure.
we use a gentlemen we found on digitalpoint that submits our sites to multiple directories. After a few weeks, we can track the backlink from those efforts.
