Should we buy Google AdWords? Pay for SEO services?
Well, maybe. But not without first addressing the real problem--the real problem is this:
When people search for a answers to their problems, they don't type in the name of the solution (cure), they type in the symptoms.
Think about it!
On your firm's website do you describe the symptoms at all? Or just have bullet points listing your cures?
Change the text on your website, accordingly! Then, if you buy AdWords or SEO services, use lots more symptom phrases than cure phrases in your keywords.
