There’s a dirty little reality that your “web guy” won’t tell you, and that’s this: without presence in search engines, your site essentially doesn’t exist.
That’s right! You’re one in a gigantic crowd without some expert assistance, and maybe even contracting out your seo services to a company like Constant Click who can help you come to a strategic decision about how best to optimize your site, where to spend your money, and where to focus your efforts to make your site the biggest success it can be.
Don’t trust your “web guy” to do this for you any more than you’d trust your grocery store butcher to cook you a five-star dinner. SEO can make or break your company and your site. Leave it to the pros!
