What is Google friendly Web design?
Google friendly Web design refers to one thing and one thing only: Web site design that follows the webmaster guidelines as set by Google themselves. There isn't a fancy tool or script that someone is able to write that is going to make your Web site Google friendly. There might be a tool or script that you can purchase that will help YOU make your Web site Google friendly or SOMEONE ELSE make your Web site Google friendly. But there is no tool or script written that will automatically do everything you need for your Web site to reach #1 on Google.
EVERYTHING you need to make sure you have a Google friendly Web site can be found right at Google's Webmaster Guidelines Web page.
That seems pretty easy to me, how about you? Easy enough that a baby could do it right? Surely you should not be paying someone for some SEO tool or script that is going to magically turn your old Web site into a fancy new Google friendly Web site! Especially since that information can be found for free right on Google's Web site.
You will however need to spend time with Google's Webmaster Guidelines if you want to make your Web site Google friendly. Or, you can hire an SEO consultant or company to do the job for you. But don't ever and I mean EVER pay someone for information you can already get for FREE.
