I know that bookmarking is one of the best technique for promoting website. But I want to know which one is right either 1 or 2 If I'll write "web design company in Mumbai" as a title with my website link and description ( note: here I'm writing everything about my website) If I'll write "web design company in Mumbai" as a title with my website link and original content as a short story news (Note: here content is not related to my website link but related to keyword).
Bookmarking was promotion methods in 2010 and not anymore. I see sites like digg and delicious ran out of steam. So anything you do is useless and pointless in 2014.
I agree with your statement, bookmarking may also be a waste of time as well. There are lot of bookmarking sites out there they are come and go. If you spend time on them doing bookmarking then after a while they get expired for some reason they are taken down your effort is pretty much useless in that regard.
Bookmarking is not live anymore, you can try other promotional methods to your website to promote your business.
