It depends, on what you want to do. There are cheaper ways, when you need skale - I mostly use dataforseo, it's API based only, but has good data as well and is relativly cheap, skalable and has not an Abo but Credit modell, so you basicly only pay per request, not on a monthly level, where you probably won't use all your data-requests anyway.Did they really help you a lot? What is the most useful functions of these 2 tools for you?
Well, since this is about Local SEO tools, neither is great. These tools were built to rank and study national keywords. Ok, so you can add a GEO modifier, but really useless since you can't track local keywords by GPS. Small Exception. SEM-Rush has an add-on for local that gives you Yext and some GEO-Grid ranking, but there are much better tools.I prefer Ahref than Semrush .
