Yoast SEO

Translatable meta titles, descriptions, and social tags per language. Hreflang alternate URLs injected into Yoast's XML sitemaps for posts and taxonomy terms. Breadcrumb links translated to the current language.

Rank Math

Translatable SEO meta, focus keywords, and OG data. Sitemap alternates for both posts and taxonomy terms with correct hreflang. Head hreflang stays a single source: Rank Math only emits it through a multilingual integration of its own, so PerfLocale’s tags are the only ones on the page.

SEOPress

Translatable meta titles, descriptions, and social tags. Hreflang alternates injected into SEOPress’s post sitemaps, and its term sitemaps unlocked to list every language’s terms rather than only the current one. SEOPress’s JSON-LD graph is enriched with inLanguage and the translation siblings.

Slim SEO

Schema entities get the current language’s inLanguage plus its translation siblings. Slim SEO’s own /sitemap.xml tree replaces core sitemaps, so the addon unlocks its post-type queries to list every language rather than only the default. OG locale needs no handling — PerfLocale filters WordPress’s locale, so Slim SEO emits the right one by itself. Hreflang it leaves to multilingual plugins, which PerfLocale supplies.
