Is there anything new that can be done with a directory of websites? You might have thought not, what with the way that Yahoo keeps expanding, or the user submitted places like Dmoz and so on.
The directory entries will work exactly like an in-post links (or at least will make the search engine think this way), giving more weigh to the link than any other directories. Also, the blog and ping function will enable search engine to crawl through the blog post more frequent.
That sort of functionaility, making your own site and entries more apparent to the search engines simply has to be worth paying for. Indeed, they are asking you to pay for it but only $3 which seems really like something of a bargain.
Look, the secret to success on the web is getting good results from hte search engines: this looks like it will help. For that price, why not try it?
An interesting idea, don't you think, a Wordpress Directory?
