SEO (search engine optimization) is more than just naming pages and creating keyword phrases. Keep in mind there are thousands of companies offering SEO services that do not have the real expertise necessary to do so.
If you are ever contacted by a company that offers you a free trial and asks for access info to your website…beware. This would be like giving them your home address, your front door key and telling them when you are going on vacation.
There is a lot involved with SEO, keep in mind that no legitimate company will do this for free.
It’s a good idea to thoroughly research any Internet Marketing companies that contact you before you commit to doing any business with them.
