Enabling search engines like Google to index your Wix website is an important step in optimizing your website for search engines. Here are the steps to follow:

Go to your Wix Editor: Login to your Wix account and navigate to the Wix Editor for the website you want to enable for search engines.
Click on Site Actions: In the top menu bar, click on Site Actions, then select Edit Site.
Go to Site Manager: Click on the three dots in the top right corner of the page, and select Site Manager.
Click on SEO: In the Site Manager, click on the SEO tab.
Enable indexing: Under the SEO tab, scroll down to the "Crawlers and Indexing" section, and toggle the "Allow search engines to include your site in search results" button to "On."
Save changes: Click on the "Save" button at the top of the page to save your changes.
Submit sitemap: To help Google index your website more quickly and efficiently, submit your website's sitemap to Google. Under the "Crawlers and Indexing" section, click on "Get Found on Google" and then "View Your Sitemap." Copy the URL of your sitemap and submit it to Google Search Console.
By enabling search engines to index your Wix website and submitting your sitemap to Google, you are making it easier for your website to be discovered and ranked in search engine results pages. However, keep in mind that it may take some time for your website to be indexed and for any changes you make to your SEO settings to take effect. Be patient and continue to optimize your website's content and structure for search engines over time.
