Has a pessimization filter been applied to the site?

Question

Search Engine Optimization

Recently she took up her abandoned website fins-portal.ru, hired copywriters. But search engines index the site somehow not very well. I looked at Yandex indexing, there is a slight drawdown, and on Google, on the contrary, a slight increase. How to determine if any filters are applied to the site? And through what services it can be checked?
