Yes, Google reviews do affect SEO. Google takes the reviews into account seriously when evaluating the visibility and importance of a site. The higher the number of positive reviews, the better the visibility and relevance of the site in search results. Local SEO is significantly influenced by reviews.
It should also be noted that Google prohibits [fake good reviews] as per its Review Guidelines.
Remember, Google is a search engine, it is designed to give the best results to searchers who are looking for what they are looking for or interested in. The process of improving a website's ranking on Google can take time, but with hard work and continued effort, you can achieve great results.
