How do dead links appear within a website?

Friends who do website SEO optimization will know that after running their website for a period of time, there will be some dead links in the website. At the beginning, due to the small number, some SEO grassroots webmasters and novice friends will not care. However, when the number of your website reaches a certain amount, dead links may cause your website (spider crawling does not trust and user experience is poor) and the website will be downgraded. So how are the dead links inside the website generated ? Today, Dongguan SEO editor Feng Chao will share it with you.

How do dead links appear within a website?

1. Wrong internal links are added to the website

An error in article editing or a programmer's carelessness may have resulted in a page that does not exist.

2The website is temporarily unavailable

The website is temporarily inaccessible due to server, space or program problems, resulting in a large number of server error pages with return codes starting with 5.

3External link error

A user or webmaster posted an incorrect URL outside the site; another site copied or scraped your page containing the incorrect link.

4. The crawler extracts incomplete URLs

When some crawlers extract page URLs, the URLs may become invalid because of irregular characters in the URLs or because the URLs are linked to the text behind them.

5. Website Redesign

If your website has been revamped or is about to be revamped, you must pay attention to the problem of broken links. After many websites are revamped, the previous old pages are directly deleted, resulting in a large number of broken links.

6. Administrator deletes page

Website administrators delete hacked, advertising, outdated, and spam pages, resulting in many dead links.
