I think 150-200 is enough for a day. Don't use any software for that work because its damage your site ranking results.
Hi, There is no specific number on which you should submit as the more you will submit the more you can get benefits. try to submit in as many as relevant directory as you can.
Submit how many directories you can. If you can submit 10 directories every day, after one year you have finished 3650 directories. That time you have at least 3000 good quality backlinks. so submit how many you can.
In my opinion 15-20 a day is a good amount, but if it is a new domain they shouldn't exceed 10 a day.
I think 40 to 50 directories per URL is sufficient for SEO work.I am also doing 40 directories per project.
you can submit to directories as many as you can as long as you put your sites url on relevant and correct category
Directory submission is a long process instead building quality content should be ist thing to spend time more quality post more traffic form big G
Don't worry there is no such RULES or any PRE DETERMINED limit for submission. I daily use to submit 25 to 30 or even some times 50. Nothing is happen. Just take care of ONE thing do not submit in SAME site they gives warning of DUPICATE DOMAIN or DOMAIN ALLREADY REGISTERED. If such thing happen then CHANGE the CATEGORY and then submit it will be ACCEPTED.
The more - the better. And don't fall into the "delayed" submission trick. Submit them all in a day, nothing bad will happen.
submit every new article you write to 20 directory will be excellent... 20.100 article= 2000 backlinks. huge number will gained with time.
no restriction, but i think it's enough to submit to those quality sites, others will waste your time
The more you submit, the more you gain. You won't get any penalty for submitting to too many directories, but the time/effort you put in may not worth of the gain when you submit your sites to many low quality directories.
submit as many as you can because the approved rate of directories site will be less then 25%, so more and more submission is needed? Thanks.
