This is based from my own real experience years ago. The particular type of black hat software allowed me to mass create blogs, mass post comments on other peoples blogs and mass post blog posts and comments on the blogs it created.

So as you can imagine that means a ton of backlinks. In fact the salespage first big promise was that.

The results of three or four month work was zero. Mass creating of blogs worked, but to index all those blogs it was impossible. I tried pinging, submitting blogs to blog directories,
submitting rss field to rss directories. Guess what, it is useless. Plus most of the blogs got marked as spam, they were automatically deleted. It means every comment and blog post I
posted on these mass generated blogs was useless.

The word splog came into existence after everyone realized that blogs where created for the purpose of getting links. There is an automatic system that deletes blogs if they are identified as splogs. Splogs are fake blogs created for backlinks, to improve pagerank and in other words a black hat technique which does not work anymore.

In fact if blogs are not indexed at least, the backlinks are also useless even if the blogs do not get deleted.

So why the blogs did not get indexed?

In order for a website or blog to get indexed it must get regularly and steadily amount of backlinks. Pinging once is not enough, pinging until you retire is not enough neither and submitting an rss field to rss directories might even be not enough. Why?

It is just not enough. So imagine having to index like a thousand blogs or a hundred. So mass creating blogs is not the right way to get a ton of backlinks.

The other feature of the software is to post comments on other peoples blogs.

Now this is like spamming their blogs with useless comments. Even if you create a decent comment for each blog, you are still sort of spamming. The comment section is there to comment about the blog post if you read it. If your intentions are different, then you are not commenting.

Search engines did something to shut down this spamming. Spam filters where created to stop junk or spam email. Nofollow tags where created to stop the blog commenting spam.

So all those backlinks from all those blogs, became useless overnight. Rankings drop and spiders do not like this thing. It simple means your website is no longer useful to those blogs since they removed your link. That is how spiders understand that situation.

Once again you do not need to be a genius to understand that using black hat is very risky.

Luckily for us, search engines recommend us to us white hat. They allow us to optimize our website, they like it because we are helping them by providing their customers with better quality websites. This helps you and the search engines. I will not mention the name of the software I used, but there are several similar software that spam blogs. As a newbie I had to try in order to learn.

So remember to get feedback before you try and make sure they have a money back guarantee. The results I got from this software is nothing and it took me three months testing this thing out. While I got results in less than a month using simple white hat techniques.
