EffortLess Custom Meta Tags prints meta tags in the <head> of every front-end page, from the settings in Settings > Meta Tags. On a multisite network, a super admin can also set defaults for every site in Network Admin > Settings > Meta Tags.

Settings of each site (Settings > Meta Tags):

Description: printed as <meta name="description"> on every page. A post or page with a manual excerpt uses its excerpt instead, when “Posts and pages” is ticked.
Posts and pages (ticked by default): a post or page shown on its own uses its own title, address (og:url), manual excerpt and featured image in the Open Graph and X tags, and the settings are used for the home page and as the fallback. Unticked, every page prints the same values from the settings.
Open Graph tags (off by default): prints og:type (article for posts, website otherwise), og:site_name, og:locale (the site’s language), og:title, og:description, og:url, og:image with og:image:width, og:image:height and og:image:alt, and the publication and modification times of posts. Facebook, LinkedIn, WhatsApp, Slack and others read these tags.
- Title: empty uses the site title.
- Description: empty uses the Description above.
- Image: click “Choose or upload an image” to pick an image from the Media Library or upload one, or type an image address. The size and the alternative text come from the Media Library. 1200 × 630 pixels works on most networks.
- Home page address: the og:url of the home page.
- Image alternative text: describes the shared image in the site’s language; empty uses the image’s alternative text from the Media Library. A post’s own featured image keeps its own alternative text.
- Site name: empty uses the site title.
X tags (off by default): prints twitter:card, twitter:site, twitter:title, twitter:description, twitter:image and twitter:image:alt.
- Card type: large image (summary_large_image, the default) or small square image (summary).
- X account: your @username; a profile address is also accepted.
- Title and Description: empty lets X use the Open Graph values.
- Image: empty uses the Open Graph image.
Google (structured data) (off by default): prints a JSON-LD block on the home page describing the organization (Organization: name, logo, social profiles in sameAs) and the website (WebSite: name, language). Google uses it for the logo and name in its results and knowledge panel.
- Business name: empty uses the site title. The website name is the Open Graph site name.
- Logo: chosen or uploaded in the Media Library; at least 112 × 112 pixels, readable on a white background. Empty uses the site icon (Settings > General).
- Social profiles: one address per line (Facebook, Instagram, YouTube, X, LinkedIn, Google Business Profile, TripAdvisor…).
Image preview size: the max-image-preview value of the robots tag WordPress prints (large, standard or none). WordPress already uses large on sites visible to search engines.
Text and video previews: adds max-snippet:-1 and max-video-preview:-1 to the robots tag.
Site verification: codes for Google Search Console, Bing Webmaster Tools, Pinterest and Facebook (Meta) domain verification, printed on the home page only. You can paste the whole tag the service gives you; only its code is kept.
Content-Security-Policy: one directive per line; the lines are joined with semicolons into one <meta http-equiv="Content-Security-Policy"> tag.

Network defaults (Network Admin > Settings > Meta Tags, multisite only): Open Graph and X tags and the Google structured data on for every site, default Open Graph, X and logo images from the main site’s Media Library, the social profiles, the X card type and account, the image preview size, text and video previews, the verification codes and the Content-Security-Policy. A site’s own value, when filled in, is used instead of the network default; a tag type turned on for the network is on for every site. Titles, descriptions, the home page address and the names stay per site, since each site may be in another language.
