Google has 3 ways to give business owners information about their site. Google Business, Google Webmaster Tools, and Google Analytics.
Google Webmaster gives you an idea of what the Google bots see when indexing your site, and what people are searching for to find it. Use it as a diagnostic tool to make sure your site is in good health and people can find it.
There are ways to make your site more searchable with tools presented by Google Webmaster, like search analytics, total clicks, keywords used, etc.
Google will alert you when certain things go wrong with your site (such as problems viewing on mobile) which, when taken care of, can make sure your site doesn’t drop in Google’s search ratings.
Keeping your site in the best SEO health will help drive traffic and keep your site near the top of relevant searches.
