The 404 error is the most recognizable and common hypertext document error. It reports that the page does not exist at the given address. In fact, we are talking about the absence of an html file for the specified document, so the site returns an error.

To deal with the issue in more detail, as well as with a number of service files that each resource has, you need to study the moment associated with the hypertext representation of pages using the HTML language (HyperText Markup Language - “hypertext markup language”), and the HTTP protocol, through which is being accessed. Despite the fact that you have to understand the programming language, the form of its presentation is so simple that anyone can understand it.

Hypertext pages and their features

The Internet was born at the moment when the English engineer Timothy John Berners-Lee came up with a hypertext form of representing text pages on the web and described the principle of accessing them via the HTTP application protocol. According to the general idea, the user from his device, namely from the browser, makes a network request for a specific resource. At this point, a session is opened on the server being accessed. An HTML page is returned as a response.

Of course, in our time, more complex algorithms for accessing and “swapping” large pages are used, but the general principle remains the same. To access the resource, you need a domain name and an IP address. Only if these criteria are met and the resource is in working order will a "404 not found" error be returned for the missing document.

What the default 404 page looks like

A site may or may not have a decorated "http 404 not found" access error page. A user with little experience is usually quite nervous when receiving it and believes that this is his fault. In fact, everything is much simpler, the answer follows from the above.

The 404 error code in the form of a separate page designed in the site design is returned only if the site has a 404.html file. It is usually located in the root directory. Otherwise, the browser will report this error along with a message about the lack of access. And it usually looks like a white sheet with an error message.

When developing websites, as a rule, content management systems are used. They contain a 404 page with the path to it in the functional files. Typically, such a page contains a message about a non-existent address and a link to the main page of the site. The template for the 404 page can be changed to your liking, as this is a page on your site that you can use however you wish.

In order to remake the template, you will need knowledge of HTML to mark up the file. Please note that in some cases the page file may have a different name - err404. html, 404.php. The difference from the standard is most often associated with wider functionality, as well as system features. For example, in WordPress, the document can be found in the 404.php directory. In the address bar "error 404 page not found" will be displayed something like this: domain.ru/404/.

Adapting a Standard 404 Page to Your Purposes

To improve the usability (acceptability for users) of the site, of course, it is necessary to make a page that will attract the visitor to your site and help them continue browsing. Things to keep in mind when writing code:

A significant part of visitors who encounter non-existent pages go to the site from search engines or via links on forums, sites and social networks, that is, from where old links to long-non-existent pages may be located.
Users are not looking for your site, but for information of interest by keyword, that is, in the absence of the desired one, the visitor leaves the site and rarely views it.

That is, you must understand that it will not be so easy to keep such visitors, but it is possible!

Take a standard template available on the Internet, or make your own, taking into account the above features:

Briefly explain to the person what happened and why he does not see what he was looking for. Show him the options for further actions that will help him find what he is looking for.
Display a search string on the 404 page so that the visitor can immediately find what they want.
Be sure to display the menu of your site here, with the help of which, a person can understand where to go.
Make sure that the page attracts the user, and he wants to find information on your resource. Use colorful and interesting text-visual solutions.

To make the 404 server error page attractive to the user, it is enough to cause him a smile or interest. Therefore, try to work on the originality of the idea for such a section of your resource.

Editing the 404 Page

You can edit the file from the content management system directly, for this you need to add the desired markup and images.
When creating it, be guided by the fact that information should open quickly and without delay. The page should be "light" (take up little space), useful, and offer alternatives to finding a non-existent document.

transition to the main;
list of rating pages of the site;
transition to the resource map;
a button to inform the administration about a "broken" link on a specific source.

Otherwise, fantasy, corporate standards and the designer's original idea will be the best assistant.

Conclusion

The 404 not found page is a service file that can be modified and supplemented to attract more visitors to the site. This file is required, because otherwise, the browser will display an error message, after which the chance to lure a person to you will be zero. Try to fill it with colorful images and even light humor.

This error means that the page the user is trying to view was not found or does not exist. In this case, the user himself will not be able to influence the solution of the issue. The only thing he can do is to find similar information on the same site. For example, an address with an error www.example.com/not-founded-page.html replaced by www.example.com

Why is this happening?

This is due to the fact that the user went to the site page through the wrong link. For example, the user entered in the browser (or followed the link) http://mysite.com/rbot.html, but it was necessary - http://mysite.com/ro bot.html. Moreover, this link could be located both on your site and on third-party sites. You can find such links using Google Webmaster Tools. For this we go to page of this service, select your site, and then click: Status -> Scan errors and select "Not Found".

The free program XenuLinks also copes well with this task, which you can download, and see the manual -.

How to fix 404 error?

In the traditional sense, it is impossible to correct this error, because the problem lies not in the operation of the server or the site engine, but in the fact that someone incorrectly indicated the link address. Therefore, the only way to correct it can be called identifying erroneous links, and indicating the correct address. It is also worth checking if the current page exists on your site? If it was deleted, then make sure that it appears again. If it has been renamed, then you need to set up a 301 redirect from the old page address to the new one.

When a user enters the site and sees this error through the issuance of the server, he does not see your site (menu, navigation, design, etc.). Accordingly, with 100% probability, it will close the page. This scheme works on all hosting by default. But you can program this page and show your site along with it. And this means that the user, seeing the main links of your site in the menu, can click on them and stay on the site. Here are examples of incorrect and correct output, respectively:
