This simple plugin (no configuration) redirects <code>?s=FOO</code> search URLs to the nicer <code>/search/FOO</code> versions. Requires pretty permalinks.

Redirects search URLs from ?s=FOO  to /search/foo and converts spaces to + symbols

When Facebook crawls your site, it uses the Canonical URL and links directly to this in all Facebook posts. This plugin prevents 
Facebook from seeing the Custom Canonical URL entered into the Yoast SEO plugin. This means it will always 
link to your own website, even if you’ve set the Canonical URL to another site.

Remove Yoast Canonical URL for Social

This plugin removes manually entered Yoast SEO Canonical URLs when social media networks such as Facebook crawl any page on your website.
