I think Wordstream is a great platform but if your ad spend is high it’s really expensive. For us it was quoted at $1,000 per month, and that was after a discount. If you have a high monthly budget I’d recommend Opteo instead. It’s not as powerful but it’s much cheaper and we’ve found it’s given us great recommendations.
That being said I always recommend the Wordstream blogs and webinars. All around it’s a great company, just too rich for my blood.
