Snigirev Meta & Alt

Description

A free SEO plugin: manual editing of ALT/Title/Caption/Description for
Media Library images, SEO title/description for posts and pages, basic
schema.org markup (JSON-LD, Article/WebPage), an XML sitemap and
robots.txt.

Features

• Media Library: scan images missing ALT text (global mode) and browse
  the images used on a specific page/post (“per page” mode), edit
  ALT/Title/Caption/Description, save one card at a time or in bulk with
  the “Save all” button
• Meta tags: a metabox on the post edit screen with SEO title/description
  fields, output of the tags on the front end (<title>,
  )
• Default templates (“Smart Tags”, modeled after AIOSEO): if a post has no
  custom SEO Title/Description, the site-wide template from Settings is
  used, with placeholders #post_title, #site_title, #tagline,
  #separator, #current_year, #current_date — the post metabox shows
  what will actually be output before you even save. In Settings, tags
  are inserted with a button click, and a live preview with real site
  values is shown right under the field
• Schema.org: JSON-LD Article (posts) / WebPage (pages) markup in
  wp_head, reusing the values from the Meta module
• XML sitemap at /sitemap.xml — all public posts/pages, generated
  dynamically on request (no file written to disk), can be toggled in
  Settings
• robots.txt: extra rules from Settings are appended to WordPress’s
  standard virtual robots.txt, plus an automatic Sitemap: line pointing
  to the sitemap (if enabled)
• Open Graph (og:title, og:description, og:image, og:url,
  og:site_name, og:locale) in wp_head — a single standard parsed by
  VKontakte, Odnoklassniki, Telegram and MAX for link previews. Reuses
  the same values as SEO title/description (see Meta/Smart Tags above)
• 301/302 redirects: a rule is “source (path, * allowed as a prefix
  wildcard) → destination (full URL)”, managed as a list with
  enable/disable and delete right in the admin screen (Snigirev Meta &
  Alt → Redirects), checked on every request before the page is output

Extended AI version

If you need automatic AI generation of ALT text/title/caption/description
for images and AI-generated SEO Title/Description for posts and pages,
that’s a separate paid product, Snigirev AI Meta & Alt (the full
version), not distributed through the WordPress.org directory. Details
and purchase: aiseobooster.aeropic.ru.
Snigirev Meta & Alt is a standalone free plugin that works fully on its
own, with no integration with the paid version.

External Services

This plugin does not send any data to external services. All assets
(including the select2 library used for the page/post dropdown on the
“Snigirev Meta & Alt” media screen) are bundled with the plugin and
served from your own site — no third-party CDN or remote service is
contacted, neither from the server nor from the administrator’s browser.
