Broken links are dead-links which are not good for search engine and also for your readers. Today, I will be sharing some 404 link checker tools which will help you to detect 404 and dead links on your blog.
How To Fix Broken Links
Most websites contain broken links. They are unavoidable. Over time, the likelihood that a page you linked to within one of your articles increases. There are a number of reasons that this could occur:
- The website owner changed the post slug of a page (perhaps to improve SEO)
- The website has been restructured; resulting in pages having a different URL (e.g. changing from the default WordPress structure to clean URLs)
- The website owner has removed the page
- The website no longer exists
- The website has transferred to a new domain and the owner has not set up a redirect
- The website may be offline due to hacking, a firewall, or the website owner not paying their hosting bills
The above reasons assume that a link has become broken because of a website owner changing a URL or removing the page. However, sometimes the fault lies with you, not them. It is easy to make a mistake and link to the wrong URL.
A common error is to forget to include http:// at the start of a link. When you make this mistake, browsers assume that you are trying to link to a location that is relative to your current location. For example, if I incorrectly linked to www.google.com from this article instead of http://www.google.com, the URL would be published as http://www.thehackersolutions.com/blog/www.google.com.
Why You Should Fix Broken Links on Your Website
There are many benefits to fixing the links that are broken on your website. First and foremost, you will give your visitors a better user experience. I am sure you have been reading a good article and then discovered that the links that are contained within it are all outdated. It is very frustrating. This reflects badly on the website and suggests the content is outdated and no longer relevant.
Secondly, there are SEO benefits to fixing broken links…isn’t there?
Many SEO experts say that fixing broken links, missing images, and 404 page errors, will improve your overall search engine ranking. I have found that for every person out there backing this claim up with hard evidence, there are thousands of people who state with conviction that fixing broken links will give you an SEO boost, only because they heard someone else say this. I wouldn’t be surprised if I made this claim myself several years ago because I assumed it was true.
I don’t know if it is true or not as I am not an expert on search engine optimization. Google states on their website that 404 errors will not impact a website’s ranking. This conflicts with the idea that 404 errors and broken links can hurt a website’s ranking.
Even though Google has confirmed that 404 errors will not hurt a website’s rankings, they do encourage all website owners to fix links on their website. Google also has a long history of saying one thing, and doing another; so perhaps 404 errors can damage your ranking.
For me, whether 404 errors and broken links hurt search engines is a non-issue, as it is in your interests to fix links that have been broken if you want give visitors a good experience. This is a big priority if the articles that have broken links generate a lot of traffic.
“If the links are coming from your own site, fix or delete them. If they’re coming from an external site, you can use this data to help improve your site’s user experience. For example, a misspelling of a legitimate URL (www.example.com/awsome instead of www.example.com/awesome) probably happens when someone intended to link to you and simply made a typo. Instead of returning a 404, you could 301 redirect the misspelled URL to the correct URL and capture the intended traffic from that link. You can also make sure that, when users do land on a 404 page on your site, you help them find what they were looking for rather than just saying “404 Not found.” However, this is only worth the effort if the incorrect link is generating significant traffic.” – Google
There are a number of services and software applications that will scan your website and report broken links to you. Finding broken links will show you:
- Links within your articles that are broken

The great thing about the plugin is that it can scan your database regularly and then email you if it finds a broken link. It can also apply formatting to broken links so that they are easily visible to everyone.

Fixing Your Broken Links
Once you have created a list of broken links on your website, you can proceed to repair them. There are a few ways in which you can do this.
When the broken links are on your own website, you can do one of the following:
1. Correct the Link – If you linked to a website incorrectly, all you need to do is edit the URL and replace it with the correct value. For example, one of the most common reasons a link becomes broken is because the author forgot to put http:// at the beginning. Sometimes, correcting a link requires more investigation, such as when a page you linked to has been moved to a new location or the website has completely changed their domain.
2. Replace the Link – There are times when it makes more sense to replace a link in an article. For example, when you have referenced a resource that no longer exists, is no longer supported, or has not been updated in years. The idea is to replace the website you referenced with an alternative resource. This ensures that the article remains useful to visitors.
3. Unlink the Link – If the page you linked to no longer exists, or is no longer relevant, you may want to completely remove the link from the article. This may also mean removing any content that refers to the page you referenced.
Restructuring your website, or changing the post or page slug, can cause 404 errors on your website (not found errors). This will make your internal links to the old URL invalid. It can also reduce the traffic your website receives from other websites, therefore it is important to address the issue. The most practical way of resolving the issue is to create a 301 redirect from the old URL to the new one. This ensures that traffic, and search engine juice, is transferred to the new URL.
If you have found that another website has simply linked to one of your pages using an incorrect URL, you may want to consider contacting them and advising them of their mistake. Do not be concerned if the website owner does not comply with your request, as you can always configure a redirect to handle incoming traffic to the incorrect URL. Additionally, if you have set up a good 404 error page on your website with a search bar and links to your archives, visitors should still find the page in question.
“404s are a perfectly normal (and in many ways desirable) part of the web. You will likely never be able to control every link to your site, or resolve every 404 error listed in Webmaster Tools. Instead, check the top-ranking issues, fix those if possible, and then move on.” – Google
If you have not performed a clean up of your broken links in sometime, you may have to spend a few hours fixing issues on your website. However, after you have done so, the task of keeping the links on your website clean becomes simpler, as you only need to review your website links periodically. A solution such as the WordPress plugin Broken Link Checker makes this process straight forward as you will be emailed whenever a broken link is found.
Whether fixing broken links helps search engine rankings or not is irrelevant, as repairing broken links on your website will ensure your articles remain useful to your readers. That alone makes it worthwhile.
There are many ways to find broken links on your website. My own preference is Google Webmaster Tools or the WordPress plugin Broken Link Checker. However, some of the other solutions mentioned in this article offer a more complete picture of the problems associated with your website, such as missing header tags and problematic usability issues.
