Most link building and SEO services are created in order to help their clients but mostly end up robbing their clients. The problem which makes it worse is that newbie internet marketers do not know that they are getting scammed most of the time.
If you search for link building and SEO services online, you will find countless number of SEO companies which will provide you a flat rate for their services. Common sense would dictate that every market is different and a seller cannot really provide you a flat rate for the services. Unfortunately, most SEO and lin building companies are only there to get their "fair" share of your money and will do very less to provide value to you.
Because the majority of the SEO services firms are crap, the companies which actually do know how to do internet marketing properly start sounding expensive. A lot of buyers are out there to get the cheapest SEO service out there and then complain when they do not see results.
Companies who do understand what they are doing can be found using these traits:
1. They will never quote you a flat rate for their service
2. They will look into your niche and competition before telling you how they can help
3. They will never spam
4. They will charge much more than the "normal" SEO companies but will provide much more value.
5. Most of the "better" SEO companies are located in US and Canada.
So before you start buying the cheapest SEO package, always ask how this service will help you. A cheap SEO and link building service will always provide you zero results.
