Why don't my sites show up in searches

I've been listing my sites for months on all the major and a lot of minor search engines. My site never shows up in searches anywhere... not even at the tail end.

I've read everything I can find on it and follow the general rules to prevent my site from being excluded. For example, I don't use a lot of common words just to get listed and I don't have any hidden text. My keywords are specific to what the content of my site is and even some words that I put there just to have something unique to search for.

Hasn't worked. What am I doing wrong?

well it usually takes a couple of months to get listed. mine just started to get in the search engines and it has been 6 months, do you have a robots.txt file for the robots that visit?

no. What do I put it in it and where do I put it? The root directory?

here you go
