Hello there e-commerce community. I've been doing e-commerce for around 19 years. Most of this time I've done my own website development and my own Google ad words. I've been approached by several SEO agencies over the years and have had some small successes with some of them but I was wondering if anyone here had worked with an agency that they thought was stellar. Most of the time I feel like I give them money only to watch it burn with very meager results. Thoughts?
