When I started with solo ads there were no solo ad marketplaces.
Solo ad sellers were kind of like your friendly neighborhood dope dealers.
You had to know a guy who knew a guy who knows the dealer's beeper number.
Everything's changed though.
Nowadays, you spit and you hit a solo ad provider.
They're climbing from under of every rock.
No wonder all those solo ad marketplaces like udimi, solochecker and a dozen others have sprouted in the recent years.
And they really make your life easier, don't they?
They bring all solo ad sellers under one roof, rate them and even protect you against fraud.
But here's a question nobody's asking:
Are solo ad marketplaces really as awesome as they market themselves to be?
