Blogposting service (excluding content) charge few dollars per blogpost whereas article directory submission and social bookmark submission service charge tens of cents per submission. Why are blogposts more expensive? Is it because it offers better link building/SEO value? Google likes blogs more? Or is it article directories and social bookmarks tend to be spammy and have duplicate content?
Thanks interesting, they obviously place more value on blog linking than they do the other submissions for a reason.
If the articles providing you links are unique and related to your site niche, it is the best option to go for.
It depends on directories .There are both quality and low quality directories .You need to be careful while choosing
I think one of the reasons for a higher cost for blog commenting services is the amount of time to do manual posting. I don't think it has anything to do with the perceived quality.
Blog posting and social bookmark is good if you do it manually. because it's looks more natural and google will love it.. (i think.. ) article directory is good to make some backlink too because people usually use article directory for their autoblog or something like that...
in blog posting there ll be a huge or big content which is completely relevant, unique & original (google likes such content) to your site and a dofollow backlinks (with anchor texts). So, they need to spend some time to create a blogpost for your website. So, obviously they charge more than other things.
