I’m a beginner, and when I started creating my online store, I initially tried to compile the semantic core on my own without any services or programs. It took me two days to filter and clean unnecessary keywords, but in the end, I still couldn't organize the list properly or build the website structure effectively. So, I decided to take my friend's advice and used the Rush Analytics service. In less than an hour, I read several useful articles about the service, and then in just 15 minutes, I created a complete semantic core! Rush Analytics is the only accessible tool that allows you to work with the semantic core the way you want! Completeness, reliability, and reasonable prices – that’s how I evaluate this service. I compared several programs for data accuracy myself, and the results were disappointing. So, I’m glad that Rush Analytics has come out of beta testing, and now I can confidently recommend it to other professionals.
