If you've received an email from Google about Search Console Increase in “404” pages... - there is nothing to be alarmed about!
This is usually caused by IDX listings being removed from your site because they are no longer active. It's completely normal. A listing can be removed from your site when:
The property changes from Active status to Pending status.
The property changes to Sold status.
The property is removed from your MLS.
Your LeadSite recognizes that these listings–and their associated pages–no longer exist and redirect the old links to your 404 page.
If you would like to reduce the amount of 404 pages on your LeadSite, there are two things you can do with the Find Me app:
You can turn off your Listing Sitemap entirely.
You can generate a Custom Listing Sitemap with fewer areas which results in less pages that will be removed in the future.
If any of these email reports has a specific URL that you know is an active listing and should not be a 404 page, our support team can it check out. Just send them our way to email@example.com and we'll take a look.
