Auto approve blogs are helpful, but providing they have few outbound links, pointless if the blog post has been spammed to death! Also they are very good when specific to your site. Many auto approve article direcotries have been panelized with the Panda update for non unique content.
It is advisable to use auto approve blogs to index your backlinks / Web 2.0 / Articles as most of them are heavily spammed and would hurt your site if it is used directly to your money site. CMIIW
They're usually very low quality links because of the nature (auto-approve) of them, they can still be effective, but nowhere near as effective as manually built links, from sites like ezine.
I think it's a waste of time, money approve auto posting to blogs. They are full of spam links are low quality sites, in the eyes of Google does not provide any value ... Probably a mid-quality link provides more value (and lower risk) 100k spam links.
I will be careful now on accepting articles in my blog. I named it "The New Article Directory" for Free Article Submission. But i will limit the number of outbounds links of the guest blogger this time.
70% of the websites using these methods are already spammed till death with links and links, itownt do you any good, at leass those
I would say they are useful when used as a piece of your total link building strategy. Nothing wrong with mixing auto approve links with manual links and whatever else you do. However, I still think that if two sites were identical but one had no links and another had links from auto approve sites, the one with the auto approve links would still rank better. However, just use the auto approve links with other kinds of link building.
Backlink is always help but when go to the auto approved blog, you can see there are too many spamming comment, the owner don't even care his/her blog, this kid of backlink give low value and not able to stay long. Therefore, suggest go for the quality link,quality is more important than quantity, one quality link better than thousand crap link
Auto approve blog is always a place to collect spam and duplicate message. I can imagine, a blog post have 100 comments with 100 out bound link, they will not get as many link juice as blog post with 10 comments.
Auto approved blog will get spammed. So your links will bury under hundreds of spammed links. It will not give you any SEO benefit. Also you reputation will also adversely effected.
I have tried buying a service like 1000 comment links in 5 days and what happened next, i got penalized during the Google Panda Update. Those who are using software for blog commenting will not sift which blogs to leave comment, in result your link will land in a blog that has full of spam comments. Before the Panda update, this strategy works like magic but as of the recent Google algo change, this strategy sucks. It's better to comment manually with relevant to comments to related blogs than to use software to target auto-approved blogs for comments.
I only use AA blogs when indexing my newly made backlinks, like web 2.0/profiles/new blogs, etc. They are right, it can hurt your main site if blasted in a wrong way.
It might take days before your link is detected and listed in the webmaster. Probably what you can do for now is just to wait
