If you do nothing to your website you will never get found by Google. On the other side, getting your website to rank on Google will cost you money no matter what you do.
And is why we know our monthly SEO packages are extremely affordable and well valued. We have converted many clients from spending thousands of dollars on PPC to only spend half the amount monthly while maintaining a comparable volume of leads.
No one can really say how long it takes for your website to appear on page #1 of Google. There are many algorithm and formulas that need to be just right. Some Keywords are harder than some no doubt, but we seem to do very well.
Forgetting about your Website, it is a sure way to get lost amongst the crowd. We are happy to talk to more about your SEO.
