Can you list any directorys that's still worth submitting your website to if your website are tech / music ?
I would say that instead of submitting your web site to number of directories that would be better to create pages/accounts on the all possible known social media networks.
There are some good directories around (both web & business) but it is finding the best ones to use that are going to offer you the best benefit for your niche / site. No point in submitting to the masses, A lot of web directories that are still online are not always active (look at the pending list or latest sites added) and you don't want to get to many backlinks in a short space of time because that can get your site penalised. Best Regards
The best directories are joeant.com, botw.org, directoryfire.com, dirjournal.com, skaffe.com gimpsy.com, ezilon.com, curlie.org, goguides.org, avivadirectory.com
There are still many free submission directory sites and you can just google it for the list but I prefer some premium directory sites if you have the allocated budget for it.
and how to get listed on this directory? If you can share some tips to get listed on this directory, that would be great.
I think that Google do not like paid listings and if they (Google) discover that, they will simply ignore such listing. I'm personally scared of such things.
I do not think you need to pay someone. Just spend some time to find good places. That will not take much time if you start doing that daily.
There are still plenty of good directories out there.. Google search for directories that are geared towards your niche and look them up on sites like MOZ or Majestic to see which ones have good authority. Then, just focus your time on submitting to those.
I would say that "not many", but you can still find a few if you confirmed they are still being crawled.
