Frequently Asked Questions

Common questions about Slim SEO - AI SEO Plugin, Lightweight, Fast & Automated

WordPress already has this featured! All we need to do is add theme support for title-tag. By default, the title tag will have the following format: For homepage: Site title - Site description For single page or post: Page/Post title - Site title For other pages: Page title - Site title This format is pretty good!

The meta description tag is automatically generated from the post excerpt or post content (in case you didn't enter post excerpt). For categories, post tags or custom taxonomies, their description will be used as meta description.

Open Graph inherits the meta title and meta description. For image tag, it gets from the featured image. For single posts, the plugin also provides detailed information for article section (the first post category) and article tags (post tags). It also provides additional information such as published time and modified time. Other tags such as url, site_name, type, locale are quite obvious.

Twitter inherits some tags from Open Graph such as title, description and image. So we only need to set the card type to large image, so the posts appear beautifully on Twitter.

If your homepage is a static page, then it's treated like a normal page. The meta description is generated from page content, and the featured image will be used for Open Graph tags. If your homepage shows latest posts, then it's already done automatically by the plugin.

Yes, you can. When you edit a post or a page, there's a "Search Engine Optimization" meta box below the editor, which allows you to edit meta tags if needed.

The sitemap URL is located at domain.com/sitemap.xml.

Add the following constant in your wp-config.php file: define( 'SLIM_SEO_DELETE_DATA', true );
