The best ad is one that works - plain and simple.
An article "about you" is not neccessarily the best ad. I've had one of those, and it was no better than a well-placed display ad. An "about you" ad comes and goes, fading into the past and the recycling bin.
Display ads repeat weekly or monthly, and repetition can be very beneficial.
I think it just depends on where you live, and how well it will work for you locally. Here, another arborist and I both started our businesses with small display ads in a small local paper, and the ads did excellently. That was in the 80's.
When we moved back to Beaverton 2 years ago from southern Oregon, I ran the same basic ads in the same local paper. Not one project in 10 months that I could say came from the weekly ads. Maybe $1000 down the drain.
But were it another city in Oregon, could be the opposite. I think that not commiting to a contract at first, and running a few weeks at regular price per column inch, is the way to go. Just test it first.
