what is social bookmarking, classified ads posting and press release posting? and what is the method to do that? also how they are helpful for our site?
Press releases, if im understanding correctly would be to write or have someone put together a press release for you, maybe announcing something new about your site and distributing it online.
They are all helpful in gaining backlinks which will eventually lead to better serps and also getting direct exposure/real human visitors. Social bookmarking submission: submitting to social bookmarking websites. I offer a service where my team will submit your site to 500 social bookmark sites for $47. You can see the DP thread here: http://forums.digitalpoint.com/showthread.php?t=609762 Classified ad marketing would be posting an ad promoting your website on sites like craigslist, gumtree, olx, etc. Press releases are news-worthy articles promoting your website distributed to press release agencies like PRnewswire.com in the hope that they are syndicated to/picked up by other news organizations leading to further exposure & backlinks.
