Only podcast feeds get indexed in Google Search; however, if a feed doesn't follow the\n[Atom](https://www.rfc-editor.org/rfc/rfc4287.txt) or\n[RSS](https://cyber.harvard.edu/rss/rss.html) specification, it\nmay still be indexed. Here are some answers to the most commonly asked questions about how this\nuser-controlled feed grabber works.\n\nHow do I request that Google not retrieve some or all of my site's feeds?\n-------------------------------------------------------------------------\n\n\nWhen users add a service or app that uses Feedfetcher data, Google's Feedfetcher attempts to\nobtain the content of the feed in order to display it. Since Feedfetcher requests come from\nexplicit action by human users, and not from automated crawlers, Feedfetcher ignores robots.txt\nrules.\n\n\nIf your feed is publicly available, Google can't restrict users from accessing it. One\nsolution is to configure your site to serve a `404`, `410`, or other error\nstatus message to `Feedfetcher-Google` user agent.\n\n\nIf your feed is provided by a blog or site hosting service, work directly with that service to\nrestrict access to your feed.\n\nHow often will Feedfetcher retrieve my feeds?\n---------------------------------------------\n\n\nFeedfetcher shouldn't retrieve feeds from most sites more than once every hour on average. Some\nfrequently updated sites may be refreshed more often. Note, however, that due to network delays,\nit's possible that Feedfetcher may briefly appear to retrieve your feeds more frequently.\n\nWhy is Feedfetcher trying to download incorrect links from my server, or from a domain that\ndoesn't exist?\n----------------------------------------------------------------------------------------------------------\n\n\nFeedfetcher retrieves feeds at the request of services or apps installed by users. It is\npossible that a user has requested a feed URL that does not exist.\n\nWhy is Feedfetcher downloading information from my \"secret\" web server?\n-----------------------------------------------------------------------\n\n\nFeedfetcher retrieves feeds at the request of services or apps installed by users. It is\npossible that the request came from a user who knows about your \"secret\" server or typed it in\nby mistake.\n\nWhy isn't Feedfetcher obeying my robots.txt file?\n-------------------------------------------------\n\n\nFeedfetcher retrieves feeds only after users have explicitly started a service or app that\nrequests data from the feed. Feedfetcher behaves as a direct agent of the human user, not as a\nrobot, so it ignores robots.txt entries. Since Feedfetcher acts as an agent for multiple\nusers, it conserves bandwidth by making requests for common feeds only once for all users who\nrequested the feed through an app or service. The common feeds are\n[RSS](https://en.wikipedia.org/wiki/RSS) and\n[Atom](https://en.wikipedia.org/wiki/Atom_(Web_standard)).\n\n\nYou can prevent Feedfetcher from crawling your site by configuring your server to serve a\n`404`, `410`, or other error status message to the\n`Feedfetcher-Google` user agent.\n\nWhy are there visits from multiple machines at Google.com, all with user-agent Feedfetcher?\n-------------------------------------------------------------------------------------------\n\n\nFeedfetcher was designed to be distributed on several machines to improve performance and scale as\nthe web grows. To cut down on bandwidth usage, the machines used are often located near the sites\nthat they're retrieving in the network.\n\nCan you tell me the IP addresses from which Feedfetcher makes requests so that I can filter my\nlogs?\n----------------------------------------------------------------------------------------------------\n\n\nThe IP addresses used by Feedfetcher are included in the\n[user-triggered-fetchers-google.json](https://developers.google.com/static/search/apis/ipranges/user-triggered-fetchers-google.json)\nobject.\n\nWhy is Feedfetcher downloading the same page on my site multiple times?\n-----------------------------------------------------------------------\n\n\nIn general, Feedfetcher only downloads one copy of each file from your site during a given feed\nretrieval. Very occasionally, the machines are stopped and restarted, which may cause it to again\nretrieve pages that it's recently visited.\n\nWhat kinds of links does Feedfetcher crawl?\n-------------------------------------------\n\n\nUnlike normal web crawlers, Feedfetcher isn't discovering links to crawl at all; instead, it\ncrawls a single URL that's provided to it by users of a service or app that uses Feedfetcher.\n\nMy Feedfetcher question isn't answered here. Where can I get more help?\n-----------------------------------------------------------------------\n\n\nIf you're still having trouble, try posting your question in the Search Central\n[forum](https://support.google.com/webmasters/community)."]]
