Looks like I’ll be a contrary opinion here. I think you should pay something. You had a working relationship. Every month you did not terminate her you were enabling the situation to continue.

SEO is hard to actually show proof of deliverables unless those are clearly defined. Did you pay for time spent or results?

I paid a CPA / Tax Preparer $3k to do our taxes when I first got into business. I had no idea what was normal. Turns out she cost me $10k in filling my income incorrectly and was 6 months late with the filling.

Now I pay 1/3rd that and have way better service. Whenever I think of that situation now, yeah I’m pissed at her, but also myself. It was a hard lesson to learn, but cheaper then than if I made it now.
