I am running a Adwords PPC campaign in US, UK for a Digital Marketing Agency who provides Consulting, Web development, Marketing services for leading brands. The average cost of services offered varies from $1000 to $20,000+. After a month's campaign, I am seeing a lead conversion success rate (inquiry form submission) of 4% @ $170/conversion. I would rate the lead quality 4/5.
Is this a good enough figure for this particular niche? Have you run a similar campaign recently? What's your conversion % and cost?
Consulting, web development and marketing services for leading brands can hardly be considered a niche. Your average cost of services is a very wide range. There could be so many variables even if you were referring to a niche. Why don't you do A/B testing and try to improve on your own results? Good luck.
