I have an ecommerce business that started trading a few months ago. I pay an SEO company for SEO marketing and PPC. I got quite a few sales until a couple of rival SEO companies contacted me asking whether I was happy with my SEO company, I said that I would give them another couple of months and then possibly change. Since then I have not had any sales or contacts is it possible they are using up my PPC budget or am I being paranoid? Is there any way I can check this?
