When there are too many categories tagged in your post or product, it is automatic that WP chooses one as the main category and uses it for the permalink and breadcrumbs.
Adding an additional category may lead to changes in permalink and breadcrumbs. This may make the 404 Error – page not found appear in your post or product, reducing your website’s rank in search tools like Google.
WP Primary Category will make it easier to choose the main category that you want. This works by fixing the intended category in the permalink and breadcrumbs. It is completely SEO friendly.
Easy Set-up And Use:
1. Activate Plugin. A Meta box will appear right under “Thumbnail section” in your post or product.
2. Select and save one of those tagged categories. Its permalink and breadcrumbs will appear.
3. Once users access to the post or product, that category will be used for breadcrumbs.
