Instead, your provider might expose a search\n| settings page or some other mechanism to tell search engines whether or not to crawl your\n| page.\n|\n|\n| If you want to hide or unhide one of your pages from search engines, search for instructions\n| about modifying your page visibility in search engines on your hosting service, for example,\n| search for \"wix hide page from search engines\".\n\n\nTo update the rules in your existing robots.txt file, download a copy of your robots.txt file\nfrom your site and make the necessary edits.\n\nDownload your robots.txt file\n-----------------------------\n\n\nYou can download your robots.txt file various ways, for example:\n\n- Navigate to your robots.txt file, for example `https://example.com/robots.txt` and copy its contents into a new text file on computer. Make sure you follow the guidelines related to the [file format](/search/docs/crawling-indexing/robots/create-robots-txt#format_location) when creating the new local file.\n- Download an actual copy of your robots.txt file with a tool like cURL. For example: \n\n ```\n curl https://example.com/robots.txt -o robots.txt\n ```\n- Use the [robots.txt report](https://support.google.com/webmasters/answer/6062598) in Search Console to copy the content of your robots.txt file, which you can then paste into a file on your computer.\n\nEdit your robots.txt file\n-------------------------\n\n\nOpen the robots.txt file you downloaded from your site in a text editor and make the necessary\nedits to the rules. Make sure you use the\n[correct syntax](/search/docs/crawling-indexing/robots/create-robots-txt#create_rules)\nand that you save the file with UTF-8 encoding.\n\nUpload your robots.txt file\n---------------------------\n\n\nUpload your new robots.txt file to the root directory of your site as a text file named\nrobots.txt. The way you upload a file to your site is highly platform and server dependent. Check\nout our tips for finding help with\n[uploading a robots.txt file to your site](/search/docs/crawling-indexing/robots/create-robots-txt#upload).\n|\n| **If you do not have permission to upload files to the root directory of your site, contact\n| your domain manager to make changes.**\n|\n|\n| For example, if your site home page resides under\n| `subdomain.example.com/site/example/`, you likely cannot update the robots.txt file\n| at `subdomain.example.com/robots.txt`. In this case, contact the owner of\n| `example.com/` to make any necessary changes to the robots.txt file.\n\nRefresh Google's robots.txt cache\n---------------------------------\n\n\nDuring the automatic crawling process, Google's crawlers notice changes you made to your\nrobots.txt file and update the cached version every 24 hours. If you need to update the\ncache faster, use the **Request a recrawl** function of the\n[robots.txt report](https://support.google.com/webmasters/answer/6062598)."]]
