Hi there,
I've worked a lot with adwords and I'm currently focussing a lot of time with SEO [Search Engine Optimization]
If you have a website that I could gain access to, I'd ask that we first looked at that building keywords/phrases within the actual site.
You need to edit each pages' meta data, upload site maps etc...
Also small things that help a lot would be; ensuring accurate title naming, picture alt tags, linking, accurate use of header tags, page load time and so on...
Only after that would I (Personally) consider using adwords (To prevent a loss of redundant funds) but I'm willing to help you with either or both.
