![]() These are our crawlers: User-agent: rogerbot and User-agent: dotbot. To talk directly to rogerbot, or our other crawler, dotbot, you can call them out by their name, also called the User-agent. A file configured with some content is preferable, even if you're not blocking any bots. You will want to have some content in the file, as a blank file might confuse someone checking to see if your site is set up correctly. This can also cause an error that bloats up your server logs. If your site doesn't have a robots.txt file, your robots.txt files fails to load, or returns an error, we may have trouble crawling your site. Anyone can see your robots.txt file as well it's publicly available, so bear that in mind. For example: moz.com/robots.txt, /robots.txt, and yes, even /robots.txt. You can also check the robots.txt file of any other site, just for kicks. You can check this is in place by going to /robots.txt. It's a bit like a code of conduct: you know, take off your shoes, stay out of the dining room, and get those elbows off the table, gosh darnit! That sort of thing.Įvery site should have a robots.txt file. You can use this marvellous file to inform bots of how they should behave on your site. Rogerbot is built to obey robots.txt files. Telling Rogerbot What To Do With Your Robots.txt File Rogerbot serves up data for your Site Crawl report, On-Demand Crawl, Page Optimisation report and On-Page Grader. This helps you learn about your site and teaches you how to fix problems that might be affecting your rankings. (Disallow:/) Mozused to have an awesome writeup on it but it just forwards to Moz.com/help now it could be that they have another great write up but the URL changed. Rogerbot accesses the code of your site to deliver reports back to your Moz Pro Campaign. HiI know there are two crawlers that Moz uses Roger bot and open site Explorer uses dotbot Make sure there is no forward slash '/' after e.g. It is different from Dotbot, which is our web crawler that powers our Links index. Scheduler.cs is the default IScheduler used by the crawler and by default is constructed with in memory collection to determine what pages have been crawled and which need to be crawled.Rogerbot is the Moz crawler for Moz Pro Campaign site audits. A common use cases for writing your own implementation might be to distribute crawls across multiple machines which could be managed by a DistributedScheduler. The crawler gives the links it finds to and gets the pages to crawl from the IScheduler implementation. The IScheduler interface deals with managing what pages need to be crawled. / /// Abort all running threads /// void AbortAll() / /// Whether there are running threads /// bool HasRunningThreads() / /// Will perform the action asynchrously on a seperate thread /// /// The action to perform void DoWork( Action action) Var pageRequester = new PageRequester( new CrawlConfiguration(), new WebContentExtractor()) Private static async Task DemoSinglePageRequest() PageCrawlCompleted += PageCrawlCompleted //Several events available. ![]() Var crawler = new PoliteWebCrawler( config) Ĭrawler.
