It makes you go a bit loopy if you do it too much No, what it does is create a backlink for you, adding all of those backlinks together they can raise your serps for targetted keywords and phrases, resulting in possible traffic from the search engines.
links are important for the traffic needs a 'route' or 'path' to reach it's destination. Alway link for traffic, never for pagerank.
Do you think that submitting to manually would be better or paying someone 20 dollars to submit to 500 of them?
manual submission of course....or if the person that you pay is doing it manually and good that works too...
HI You also may get some traffic from the directories but not that much... it is more to just build your backlinks so you get a better SE ranking. Thanks Tom Dahne
