A site can be simple, but needs to be easy to navigate & get found. If you listen to anyone or everyone who has an opinion, you would never get anything accomplished. You do not need to hire a "Designer" or know about "W3.org"
to have a successful campaign. Yes these are very HELPFUL tips, but not 100% necessary!
You can do your own research on:
How to build a website/ how not to build a website
How to blog/how not to blog
How to list your business
How to optimize your website
How to perform Search Engine Optimization
How to use Webmaster Tools
How to use Social Media for your business
The internet provides a wealth of information most don't know is there. Are you gonna listen to someone who has built a business website that can't be found "Organically" or "Naturally" in more than one service area? Or are you gonna realize you DO NOT need to spend all kinds of $$$ to get your business found without looking embarrassing.
