NOW days link building is very strictly so do carefully. choose only high pr sites for bookmarks your sites such as reddit
Yes, you can use thousand of book marking site for one page but I prefer you to change the title or description after submitting some sites.
Yes why not. But use only quality social bookmarking website. One thing very clear that we use bookmarking for fast crawling of any search engine, not for traffic. It give traffic to your website in some rare case or 1 of thousand.
Yupp! one web page or url can be submitted to many social bookmarking sites. It is a good strategy to drive traffic on site and to increase site popularity.
Yes, You can submit your site more than 100 bookmarking sites but you have to resource. You must do bookmark slowly not fast. It is a good strategy to get more traffic.
Only few social bookmarking sites can deliver traffic to a site, elsewhere don't! If you want traffic as your main target, focus few! If you want backlinks from social bookmarking sites, you may submit a page to 100 or more social bookmarking sites.
Of course you can but you have use different title or keywords. You need to use random keywords for submissions, you must have to use different Descriptions for submissions. Also you need to submit slowly not all in a day.
Ya definite, you can do social bookmarking for a single page. But if you do that in only one day it will be penalized your site.
Submitting a single page to hundreds even thousands of social bookmarking sites is possible with the use of automated tools. But you have to remember most of the sites that you're gonna submit to using tools aren't high-quality sites. For me, it's better to manually submit a page to a small number of high-quality social bookmarking sites.
You can do but according meyYou should use only high page rank sits. it is batter for your time and your SEO.
Yes you may submit a single link into various social bookmarking sites but if you change your description and title for that particular link then it gives you more profit.
How can we determine the quality of a bookmarking site? I mean should I check the PR , Alexa or any other thing?
