Ahh, but what you suggest is sacrificing main/popular keywords for the cheaper, less succesful ones. It may be cheaper, but less people will type those in, and any check on a keyword tool will confirm this.
Result will be: Less cost, but lower clickthrough. Can't have it both ways, bcos the decent keywords will always be expensive and is how Google makes its money. But easier keywords are small potatoes and won't give the same results as you'll get from popular main keywords. I'll bet that whatever bid you set these keywords up with, within 4 days you'll be paying £1.50 a click for junk keywords. Why? bcos everyones doing what you suggest and that must drive the cost/bids up.
Sorry, but I'd rather spend it down the pub, I'd get more satisfaction from it.
My advice is if people can't do PPC, then either learn to do this yourself for free or else stay away from it and use PFI.
Not at all

I bid a maximum of 5p per keyword, and as you know, once you set a maximum, that's the most you'll pay. As I explained previously, I ran the whole campaign on an average cost per click of 3p. 1500 visitors in 2 months for £45. Average 3p per click, maximum 5p per click.
Using key
phrases rather than key
words is a good way to keep your costs down. Many of the keyphrases I bid on included the word "Christmas" or "Xmas", which you would expect to be expensive at that time of year, but because I used phrase matching, exact matching and negative matching, and pointed each keyphrase to a very relevant page on the website, my costs were kept down yet I still got 1500 clicks (viewing an average of 3.3 pages per visitor - not just landing and then scooting off within 2 seconds) for £45. Using key phrases, matched using the methods I've just mentioned, means my ads still showed - and I received clicks - for searches for "Christmas gift", "Christmas present", "Christmas ideas", "Christmas dinner", "Christmas decorations", "Christmas crafts" etc etc.
There's no great mystery to AdWords - like you keep saying, you can of course learn to do it yourself. But, like we all keep replying, not everyone has the luxury of having enough spare hours in their day to study the techniques and experiment with them. And that's where professional PPC practitioners have their uses
Clearly we're never going to agree on this - you think you're right, and I know you're wrong

- so let's just agree to differ, eh?
