Here is a great test of your web site SEO or Search Engine Optimization suggested by Tim Healy a co-founder of TNT Dental. Google your dental practice phone number. What comes up?
The first result should be your dental office web page. No excuses. There may be someone else in the Googleverse with the same name as you but no one else has the same phone number.
If a directory like white pages or a reverse phone number finder comes up then your dental web page is not well SEO optimized.
