new to the forums, so Hi All !!!!

Paid search (Adwords) can be very effective, but you need to target your kw's properly. Seekt hose phrase that arent researchers and you have a better chance of converting.
With regards to match types, ALWAYS start with "phrase" match or [Exact] match. Never start of with a raft of board matches, cos it will cost you a fortune and you wont make any money.
Finally, same with SEO, target less competitive keyphrases that are (a) cheaper and (b) still very targetted,
As for not buying text links becasue your blog links are working, Google likes marketing mix, so always best to add variety to your types of link.
Good luck !
