One way to check if a site is accessible to search bots is to examine the website's "robots.txt" file. This file is a standard for webmasters to communicate with search engine crawlers and control which pages or sections of the website should not be crawled and indexed. You can access this file by adding "/robots.txt" to the end of the website's URL, for example: "https://example.com/robots.txt". If the site is accessible to search bots, you should be able to retrieve this file without encountering any error messages or blocks. Additionally, you can use tools such as Google Search Console to monitor the crawlability of your site and identify any issues that might be preventing search engines from accessing it.
