For example case sensitivity. Even the alleged tips are misleading as they try to mix you up in regards to well known and documented tips for search engine placement. The last three before starting my internet business were spent in the telemarketing industry. I left this industry disgusted with the moral fibre of some of the companies in the industry. To be honest almost all of the small organizations not associated with large companies or organizations are scammers of the worst kind.
Misinformation are common tactics used to sell and promote products.
I have been researching search engine reports and services for about a month now for a feature article and what I have found so far is not good. The same tactics seem to be pretty rampant on the net as well so companies that aren't household names and are selling information or services should not necessarily be taken at face value. Check them out thoroughly and definitely check all testimonials. Better still ask them for a list of purchasers or trial software if it isn't available. Choose the ones you decide to contact and ask them specific questions so you don't take much of their time.
