I do 40-50 submissions to different directories a day and I use 3 different set of topics and descriptions. Is it enough or I need to change them more often otherwise Google will punish my site???
you're already putting in more effort than i ever did, and i get good results from HEAVY submission, so i dont think you need to worry
I would use a lot more. I generally use an almost unique description for every submission and wary the anchor text almost as often.
I would say change your title every 100 submissions and change the description more often if you can. Unique descriptions help your sites a lot.
It is good techniq to give different descriptions. There is no harm in that. Instead it is good for your site
I just alternate my title descriptions , i don't think you need to worry about the actual description of the site.
I appreciate for every comment !!!!!!!! I think every 50 submission are you change your targeted keywords and also description for your difference pages.. It's very helpful to your site .....................
I think it is a good start for a new site. But sooner or later, that number of submission will be too much. Try other SEO techniques because ranking is not only about directory submitting.
i think its best to have a different set of title, descrip and keywords to cycle through every 50 directories or so.
