I know DMOZ takes a while to list once you have submitted so its not always an instant method. As its an open directory project, they are making no money off it and therefore no express submit options as far as I'm aware.

It's almost 8 month before i have done that still its not listed .

As far as I know, there is no express inclusion into DMOZ. I'm still waiting that DMOZ includes few of the websites I've done before a year or longer to get included, however in past some websites got included in matter of 3-4 months. It depends alot how many people are working on the categories or sub-categories, often noone works on them so it takes very long till someone actually gets to your submission.

Yes i agree with you . I know view people whose site are included in Dmoz with in 3 to 4 month but i don't know what to do with my site .Even i read some seo blogs where they say that DMOZ can give huge traffic to my site .

DMOZ known as open directory site. Can anybody tell me, what is the meaning of open directory?

No idea about open directory.

Hi,
I also try many times to submit site information in dmoz but It's not accepted, I think you should not waste your time for submit site in dmoz and I suggest you to submit in other link in many other do follow sites that have high PR.

I am doing that also but getting listed in DMOZ matters a lot .It will help to get lot of traffic for my site .

Would I be correct in thinking that they have a very strict criteria for their listing? - If so, does anyone know what the criteria is?
