I just want to know is it safe to bookmark each page of your website on different social bookmarking sites or it will be considered spam or it is against search engines guidelines.
Of course everything that is than in mass scale and is automated can be considered as spam but if you will properly mix titles and descriptions while doing your submission I believe you will do more good than bad for your website.
Mix things up by using related keywords, if you start to run blasts of mass links then you cannot stop as this will not look natural at all!
well it's still much better to submit links with varied titles and descriptions - so that you can maximize your keyword usage
As long as there are different title, keyword and description for each link then there is no harm in submitting the different pages of your site to the same bookmarking site.
If you do it so that it seems natural then it is alright, but if you blast through 300 sites in one week then there might be a chance of the penalty.
As most of the webmasters believe then everything that is done by automation is considered as spam But I am using social bookmarking for all pages within my website and haven't had any problems doing it, actually each time I do new submission I get increase in traffic so it is safe to use this strategy for your websites as well
It is depend upon your keywords, because we know very well that in one URL we can't take 10 keywords for that. but if you categorize with different URL for different keywords then it is useful and it is not spam.
