Is Google screwing with me, or am I just a Bonehead?

Hi Guys,

I would be really grateful for your thoughts on my recent discovery....

Let's use the words -

'barbeques for sale' and 'bbq's for sale' just as an example....('sale' being the word in question)...

I used both my keyword software and Google External, to find that both of these phrases in "quotes" came back with 15,000 to 22,000 searches for the month respectively. Great!!!

I then found out that the competing pages for both terms were a mere 1200 and 2000! Okay, now my adrenalin is causing my eyes to bulge. Double-checked and tripled checked to make sure I wasn't imagining this...then raced off to Go Daddy to snatch up some domain names.

However en route, I slammed on the brakes because I knew something just didn't seem right. Why would there be so many monthly searches with such unusually low competition for a very substantial market?

Then I thought, maybe it's because most of these searches are for people who are wishing to 'sell' these items, not 'buy'? Why? When I looked at the top 10 in Google, not one of the major hitters and manufacturers that produce Barbeques were on that first page.

Certainly not all, but many sites were either craigslist, freeads, and a couple of classifieds and articles.

So am I reading this correctly?..... that this is the reason why so many searches with so few competing pages, is because people are not wishing to buy barbeques using these keywords, but rather 'selling' them instead, thus myself barking up the wrong tree? - or have I actually found a couple of golden keywords otherwise?

Sorry if this is a stupid question Guys, but I was just wondering if this is the typical - "if it's too good to be true, then it most probably is" scenario? (I'm not suggesting that this is in fact impossible, but at least in my experience, it seems pretty darn rare,, hence my dilemma).

Thanks for your opinions!
Mark
