For those of you unfamiliar with egaroo.com and bla.st, they are both visual web directories - with egaroo using banners, and bla.st using a custom business card sized format. Both offer the ability to add your own image and link to your site for free, but one of them comes out on top. Measuring my traffic between April 9 and June 15 (the day since Citrik Acid has been posted on both sites) I came up with the following results.

Egaroo

Egaroo calls itself the free web banner search engine. Searching for "Design Blog" or "Website Reviews" both show Citrik Acid in the top 5 spots, which shows that it works. However, the horizontal format of the banners makes it difficult to browse – and unless you know what you're looking for it can be hard to spot. Unlike their search results, the traffic impact was not that great. In the 68 days that Citrk Acid has been listed, only 9 people have clicked on my banner, with only 66% of them being new visitors, and a 55% bounce rate.

Bla.st

Bla.st – which I previously wrote about – has offered me better results, giving me 33 visitors with 88% of them being new. Bla.st also boasted a much lower bounce rate at only 46%. The Bla.st structure is more conducive to general browsing, and because of the business card sized images are much easier to read and look at. Bla.st has increased my daily cost to 4 cents / day due to me blogging about them, but this is a recent change, and did not make much of a difference in the statistics.

Overall I am more happy with Bla.st, but still recommend listing your website(s) in both directories. The extra traffic never hurts, and the links to your site can help increase your search engine rankings.
