It also has a Preview that I see fairly often, though who knows what it’s for: UA: Mozilla/5.0 (compatible SeznamBot/3.2 +) Memo to self: See what interesting things happen if I give my primary site an IPv6 address. (This may not be wholly accurate, because only my personal site has an IPv6 address, and therefore it is the only one whose logs show IPv6 requests. Seznam is the only search engine I routinely see from IPv6. I don’t have a single word of Czech-language content. Year after year, active out of all proportion to its population. Listed here in order of overall frequency. I do still get the occasional image request giving Yahoo Search as referer. So rare, I frankly don’t know why it still bothers. UA: Mozilla/5.0 (compatible Yahoo! Slurp ht jtp:///help/us/ysearch/slurp) I don’t think it’s actually a preview I think it’s more of an accessibility tester. UA: Mozilla/5.0 (Windows NT 6.1 WOW64) AppleWebKit/534+ (KHTML, like Gecko) BingPreview/1.0bīing Preview always comes from the 65.55 range. Is quite rare compared to the mobile Googlebot, well under 10% of all requests. :: insert appropriate ROFLMAO emoticon here :: But, as discussed in other threads, msnbot suddenly reappeared in October 2019. The once-common msnbot-media seems finally to have retired. ![]() Mozilla/5.0 (iPhone CPU iPhone OS 7_0 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11A465 Safari/9537.53 (compatible bingbot/2.0 +) This is by no means a complete list they are merely the ones I have personally seen in the past year. There also exists a Googlebot-Video, but since I don’t have videos, I don’t know anything about its behavior. So far, it hasn’t picked up anything but PDFs. The final, shorter Googlebot UA-the one without “Mozilla”-made an isolated appearance last March (2019), but didn’t start showing up regularly until November. It is comparatively rare-less than 2% of all Google requests-and is limited to supporting files, mostly images. ![]() The Safari Googlebot first showed up in May 2018. By now, I think most robots do this, having figured out that a site may send different content depending on which page a stylesheet belongs to. Both Googlebots always send a referer when requesting scripts and stylesheets. The mobile Googlebot does about 2/3 of what’s left, or about twice as many requests as the vanilla googlebot. It is responsible for about 1/3 of all Google requests it never sends a referer. Googlebot-Image does what its name indicates.

When I say “abc” in an IP, it means that the final segment is always the same number, but I’ve obfuscated it. This year’s article is about robots that have made it to Step 4, out of sight, out of mind. I know the Googlebot exists I’m not especially interested in what, exactly, it does. Step 4: If an authorized robot gets in the habit of visiting regularly, week in and week out, it eventually goes on the Ignore list: when I process raw logs, its requests are disregarded. Step 3: Once a robot has convinced me it intends to be compliant, it gets authorized, typically in the form of un-setting any violations it has committed (such as failing to send the Accept: header, or coming from an unsavory neighborhood). If you request any of those pages, you can be relatively confident you will never proceed to But one roboted-out directory contains pages that are linked from the root. Obviously a brand-new robot will not find its name in the Disallow list. If you don't ask, you had better have a very good reason for existing. ![]() before you ask for any other file, including the root. Brief background: On my site, new robots have to pass through an approval stage. ![]()
