When a web page does not exist on a website and a visitor tries to access, resulting in an error (an error saying: Error 404). To enhance the error message, webmasters can create a custom message. This allows for example to link to the home page and explain to visitors why they agreed to this error. There may even be a link to return to the previous page. This tutorial can easily create such a page.
You must remember that these errors are not always under your control, so for that so you should always create the error page. It is also recommended that this page must contain a brief explanation of the possible reason for the error next to the logo of the page and links to Home, site map, help, etc. This is because the visitors coming on your site must not go and get informed about the issues. They must also get more options to deal with current situation by visiting other links.
Always keep an page and remember that a common error page for all is not recommended. It is true to an extent that some of the errors are out of control and the user must understand the same to extent for the goodwill of your website. Similarly a clear concept for those errors which cannot be rectified should also be constructed. The best example is of deleted data. The user must understand the data is deleted here and there is no solution available for the same.
You must identify each of the errors and create specific pages for that which can help users keep him going away from the site and you will also have the record of number of users who are visiting the error page. This helps you to get statistic of users and pages when the site falls.
What are the most common reasons for HTTP Error 404 :
Broken Link : The first one is Broken link. This error has no good reason and under every condition this must be corrected. This error is caused by a neglect of the person responsible for maintaining the site, it usually happen when you move pages or files in place and are not updated links to other pages on the same site that point to them.
Search Result Broken Link : A second reason for the same can be a broken link from a search engine: Some search engines index sites automatically every 2 or 3 weeks, so if you are responsible for maintaining the site move, delete or rename a page and the search had a link to her index will occur again a broken link to the search engine automatically re-index our site.
Page Expire : The third reason is that if sometime the pages expire or move. There is also no good reason behind this error and it must be corrected soon.
URL: The fourth reason for getting this error is at the time of writing or copying a URL. This error can be controlled by providing simple and consistent URL. Sometime due to typing mistake or entering wrong url can cause this issue also.
Forms : Fifth reason is can be due to Data entry on a form. A form, often maintaining a website, mistakes are often unintentional and in some cases, the scripts that control the forms are deleted, moved or renamed. When we click on Send Information on our site, this script calls a script and if not found, error 404 will appear.
Expired Session : And the last but not the least reason can be expired session. This error occurs when the requested page is under a secure server or within a user session. If your session ends must re-enter the username and password.
Some Points before making a 404 Error Page
If possible set the view of site map on the 404 page. This allows the visitor to find themselves lost on the interface of the site and start to conquer the web pages by using other links. This error occurs when the server could not handle the request due to the fact that file access was denied. Error 404 (File not found) occurs when a user requests a Web server document which does not exist on disk. That is, when a user requests a nonexistent file.
This is the most "popular" of all the errors. You can observe the occurrence of such errors in the error log file and consider it - keep track of which documents on the server "not found" and to correct incorrect references in your html-documents. Also, links to non-existent documents may lead to other sites.
Do not use complicated error pages. This might prevent the visitor to search for other links on the webpage they will quiet fast to other sites. If possible the error page must automatically redirect the user to the home page.
For webmasters who master a complex language such as PHP, it may be possible to develop a sophisticated script that parses the URL error in order to root out the keywords. These can then be used to search and offer the most relevant pages according to research from the Internet. Although I do not know of websites that have used this method, I think this is one of the most ergonomic solutions and it totally customize this error page.
It really makes sense if you can highlight the most popular pages of the website in question. This is particularly an advantage on a blog, because there is no specific purpose for the visit of an Internet apart from the reading of interesting articles. In addition, your most popular pages have managed to please a wide public, this means that the subject or title is quite seductive. By providing these links to the 404 page, this will encourage users to click and thus leave the 404 page.
Finally, we must not lose sight of that site visitors are used to design the pages as usual. The 404 error should not escape the rule requires that the graphic identity will be kept to disturb anyone. In addition, if the menu is always present, it allows the visitor to redirect itself to a page considered as valid.
