This may lead to drastic reduction in rank and block in traffic. It is not always possible to simulate the exact running environment of the site and hence the results of automated SEO may not be accurate. Many times, the submission details provided by the SEO tools are nowhere near the exact figures.
The best utility of the automated SEO tools is in those areas that check the site for compliance with standards. Automated tools for analyzing inbound traffic for the website and comparison with competitor sites and the number of link in the current site will provide a comprehensive outlook from SEO perspective.
So it is always better to use automated tools prudently. Extreme dependence on them is a clear waste of money and resources. However, usage of proper tools for the right tasks will save a lot of time and prove to be extremely efficient.
Human beings always want things to be easy and fast. This is the reason why we always fall for promises that automation gives, especially in work and business. In the world of Internet marketing, there exists automated SEO services and many marketers are falling for it. Real experts on SEO warn against the use of these services though. If you are someone who is thinking of using automated SEO services, then you need to know the reasons why you need to avoid them like the plague.
They can hurt your site ranking
Probably the best reason to avoid automated services is because they can hurt your site ranking. This is because in these services, only a single title and description for the site is used and then the information is submitted to hundreds or even thousands of web directories. This could sound the alarm against your site and search engines such as Google can penalize it. You don't want to be known as a spam producer right? So stop using those automated services.
Directories change their rules all the time
Web directories change their rules all the time. They do this because search engines like Google also change their rules all the time and also because of tough competition. If you will use an automated service, then there is a good chance that you will bypass or violate these rules. In the process, your site may get rejected. When you submit manually, you will be able to know the rules and adjust accordingly. So far, no automated service can successfully detect rule changes in web directories. Until such a service exists, you may want to stick to manual submission.
Do you really know a successful website that is using an automated SEO service? I bet you don't. The effectiveness of these services is not proven. Please don't fall for the lofty claims and the promises that these services make in their sales pages. Keep in mind that if it is too good to be true, then it probably is. Some services promise gazillion backlinks for a very small price. It is actually better if you will just stick to methods that will cost you more but won't endanger your site.
If you have money to spare then instead of spending it on an automated service, just hire a manual submitter that can help you with your SEO needs.
