Frequently Asked Questions

Common questions about Related Posts for WordPress

Settings > Related Posts.

Yes, set the excerpt length to 0 in the Related Posts for WordPress settings screen.

Yes, it's in the Related Posts for WordPress settings screen. To change only the space between the posts or the width of the images, set the CSS custom properties --rp4wp-gap and --rp4wp-image-width in your theme, for example .rp4wp-related-posts { --rp4wp-gap: 2rem; --rp4wp-image-width: 25%; }.

Yes, clear the CSS field in the Related Posts for WordPress settings screen, or use the rp4wp_disable_css filter: add_filter( 'rp4wp_disable_css', '__return_true' );.

Yes, you can use rp4wp_children();. More information on the theme function can be found here.

Yes. To display your related posts via a shortcode use: [rp4wp]

Yes. Use the limit attribute, for example [rp4wp limit=1] for one related post, and the offset attribute to skip the first ones, for example [rp4wp limit=3 offset=3] for the fourth to the sixth.

Yes there is!

No, the free version does not. The premium version however does, get it here.

It keeps the 25 most telling words of every post: words that are in the post often and in few other posts, so a word that is in every post on your site says little. The words of the title count 5 times, and the categories, tags and posts a post links to count as well. Common words like "the" and "and" are ignored in the language of each post, in 57 languages. Posts that share the most telling words are related, the most related first. There is no minimum score, so a post gets as many related posts as you chose whenever enough posts share a telling word, a category, a tag or a link with it. Words that are in very many posts don't count for this.
