The answer is: it's incredibly unpredictable. Since DMOZ is a volunteer project and the editors are taking time to review sites, it can take anywhere from "minutes to a few years," according to forum member Birdie.
When you suggest a site it can take anything from a day to many years. Do not resubmit your site at any stage, simply suggest it once to the most appropriate category. Once you have done this there is nothing else that you can do and anything else that you attempt will only be detrimental to your cause. Move on and promote your site elsewhere. Cheers
I would agree with the previous posters that it is not very predictable as to when your site will be added to DMOZ. I would just submit your site and not worry about it. Being in DMOZ has very little to do with how you rank in SERP. It doesn't help much. Having quality content and a reason for people to go to your website along with SEO matters far more than being in DMOZ. The real value of DMOZ in my opinion is that it add value to the Domain if you want to sell it. Its window dressing and adds the perception of value.
DMOZ takes too much time to listed your website, i submitted 2 websites before 3 months ago and still i am waiting to listed these site.
Thats because you expect DMOZ to be a listing service for you...which they arent. You are SUGGESTING a site, it may or may not be reviewed and the time factor can be a day to many years.
@Kyle Stester: We rely upon volunteers to process listing suggestions. It's not reasonable to say that we're to slow when I can find no evidence that you've ever volunteered to become an editor yourself .
You might just like to read another thread, sort of the one next to this, before you post, but to help you if you have trouble reading https://forums.digitalpoint.com/threads/how-to-get-a-guaranteed-dmoz-listing.2640437/page-3 Oh and to risk repeating myself in several threads, offering to pay for a listing can get your site banned forever.
