Then, click and drag the Page title metric from your Dimensions box down into the Filters box. Then, choose the filter “contains” and start typing in the page title of your site’s 404 page:

How to Fix 404 Errors in WordPress

Now that you know how to find 404 errors using Google Analytics, it’s time to do something about those broken links. Here are some tips on how to fix 404 dead links.

1. Find Your Source URL

Use the MonsterInsights or Google Analytics 404 report method to find where your 404 links are.

2. Set Up 301 Redirects

If a page moved or was deleted, that’ll cause an error. Set up 301 redirects to point users in new, correct directions.

If you want an easy way to do this, use the All in One SEO (AIOSEO) redirect tool. Then, if a visitor finds and clicks on the old link, it sends them to the new, correct URL.

AIOSEO is the easiest plugin for monitoring and enabling 301 redirects on your site with their Redirection Manager.

Use data from Google Analytics to find these links and redirect them to the correct URLs, or fix them if you’re able.
