What is robot text file to crawl website

Understand the limits of robots.txt
Before you build your robots.txt, you should know the risks of only using this URL blocking method. At times, you might want to consider other mechanisms to ensure your URLs are not findable on the web.

·         Use the right syntax for each crawler
Although respectable web crawlers follow the directives in a robots.txt file, some crawlers might interpret those directives differently. You should know the proper syntax for addressing different web crawlers as some might not understand certain instructions.
·         Ensure private information is safe
The commands in robots.txt files are not rules that any crawler must follow; instead, it is better to think of these commands as guidelines. Googlebot and other respectable web crawlers obey the instructions in a robots.txt file, but other crawlers might not. Therefore, it is very important to know the consequences of sharing the information that you block in this way. To keep private information secure, we recommend using other blocking methods, such aspassword-protecting private files on your server.

  1. Well if you did I have not received anything yet. Should the rolex replica watch arrive I will email you with thanks, excuse my previous email but was advised to send you this considering the length of time closing this matter. I received my replica watches uk yesterday. It was working when I opened the parcel and it is still working, keeping good time, so thank you for all you have done and please excuse the one or two emails that sounded angry. I received replica watches sale but one of them has few problems, a missing screw on the back cover , the main circle turns but has a rather large vertical play, seems it is not fix properly, and a front rivet screen is missing. I have no problem to fix back the screw. If you have rolex replica sale but the rivet in the front and the rest, I do not know what to do, to be honest I am not satisfied that rolex replica sale has so many problems. I want to return it, can you please send the return address. You can make a refund when you receive rolex replica sale back. Do you have any other suggestions.
