Xenu is a spider crawling simulation tool that is very important to SEO. It is an English software, but it is very simple to use.
Enter the URL into the first option box. There are several optional parameters on the interface. The option box in the upper left corner allows users to choose whether to check external links.
The first text box below is to treat a certain URL as an internal link when crawling. For example, if you have several websites linked together, starting from the first URL entered, other websites can be detected at the same time by crawling.
The second text box is to exclude certain URLs, such as some functional links on the website, links with scripts, etc.
After Xenu runs, you can see in the results which links are wrong or can't be opened, displayed in red in the software.
In addition, you can see the text type of the page, its size, the number of layers it contains, and the number of internal and external links.
After the query is completed, a report will also be generated
No matter how serious the webmaster is, it is difficult to check these links, which can be easily found using this software.
