Hello, Yury,
We provide support for XStore theme, but your question is independent of the theme. We want to help you still, so we are trying to explain and give some suggestions:
– Unfortunately, we are unable to assist you with the Google search results as the theme is not responsible for them. We suggest that you contact the support team of WooCommerce (https://wordpress.org/support/plugin/woocommerce/) to create a correct sitemap, robots.txt file, and possibly install an SEO plugin (you already installed SEO plugin so support team of the plugin should be able to assist you) for better optimization of your pages, followed by reindexing your site.
– Read this article – https://www.wpbeginner.com/wp-tutorials/how-to-add-a-favicon-to-your-wordpress-blog/
– In our demos, we use Yoast SEO plugin. If you can’t get assistance from Rank Math SEO plugin team, you can try the Yoast SEO plugin.
We hope this information is helpful.
Kind Regards,
8theme team
