RSS Feed
If your RSS feed shows full content, then there are possibilities that your content is scraped and used in many other websites. That creates duplicated content and thus decreases your website's trust.
To prevent that, Slim SEO shows a notification in the WordPress dashboard, telling you to switch your feed to show summary.

In addition, to prevent the content copying problem, it automatically adds a link back to your posts. So, even if someone scrapes your content, you will have a back link from them. Google and other search engines will know your content is original.
How do I change the text of the anti-scrape link in the RSS feed?
Yes, you can. Use this snippet to change the text:
add_filter( 'slim_seo_feed_text', function( $text ) {
return 'Read the post';
} );
