Title: FLEX SMM & SEO Author: Flex Plugins Published: September 13, 2026 Last modified: September 13, 2026 --- Search plugins ![](https://ps.w.org/flex-smm-seo/assets/banner-772x250.png?rev=3694175) ![](https://ps.w.org/flex-smm-seo/assets/icon-256x256.png?rev=3694175) # FLEX SMM & SEO By [Flex Plugins](https://profiles.wordpress.org/flexfields/) [Download](https://downloads.wordpress.org/plugin/flex-smm-seo.1.2.5.zip) * [Details](https://wordpress.org/plugins/flex-smm-seo/#description) * [Reviews](https://wordpress.org/plugins/flex-smm-seo/#reviews) * [Installation](https://wordpress.org/plugins/flex-smm-seo/#installation) * [Development](https://wordpress.org/plugins/flex-smm-seo/#developers) [Support](https://wordpress.org/support/plugin/flex-smm-seo/) ## Description **FLEX SMM & SEO** is part of the FLEX plugin suite from **FLEX LLC** (https://flexible. am/). The display name leads with SMM, not “Flex SEO”. It is not affiliated with third-party plugins such as Flex SEO Meta Updater. It covers everyday SEO and social sharing without a bulky suite: * Overview dashboard with missing titles/descriptions and a setup checklist * Per-post Google / Facebook / X preview, color length meters, and on-page checks * Category, tag, and custom taxonomy SEO fields * Title templates (`%%title%% %%sep%% %%sitename%%` and related tokens) * Open Graph, Twitter/X cards, Facebook App ID, and social profile URLs (schema` sameAs`) * XML sitemap with selectable post types and taxonomy archives * Organization, Article/WebPage, BreadcrumbList, and WooCommerce Product JSON-LD * Optional Insights (Search Console + GA4) via your Google Cloud OAuth client * Tools: on-page audit, bulk titles, IndexNow, validators * Webmaster verification tags (Google, Bing, Pinterest, Yandex) * Breadcrumbs shortcode `[flex_seo_breadcrumb]` Use Flex Redirects for URL redirects. Admin CSS and JavaScript ship with the plugin. There is no telemetry and no remote update checker. Google APIs and IndexNow run only after you save credentials or turn those options on. #### Privacy Titles, descriptions, robots, social settings, and webmaster codes are stored in your WordPress database (site options plus per-post and per-term meta). Only administrators can edit them. **Google Insights** (off until you connect): Client ID, Client Secret, and optional GA4 property ID are stored in site options. Access and refresh tokens are stored in a non-autoloaded option. When you click Connect Google, this site sends you to Google to authorize read-only Search Console and Analytics access, then stores tokens locally. Report requests go to Google’s APIs. Disconnect revokes the tokens. FLEX SMM & SEO does not send this data to FLEX. **IndexNow** (off by default): when enabled, published or updated public URLs are posted to IndexNow so Bing and Yandex can recrawl them. A key file is served at `/{ key}.txt` on your site. Per-post and per-term SEO meta is left in the database if you delete the plugin, so you do not lose editor work on reinstall. See **Third-party services** for URLs, terms, and privacy policies. ### Third-party services These services are optional. No Google or IndexNow request is made until you save credentials and connect, or you enable IndexNow. #### Google OAuth, Search Console, and Analytics When you save a Client ID and Secret on Insights and click Connect Google, the admin is sent to `https://accounts.google.com/o/oauth2/v2/auth`. Tokens are exchanged and revoked at `https://oauth2.googleapis.com/token` and `https://oauth2.googleapis. com/revoke`. Connected reports use the Search Console API (`https://www.googleapis. com/webmasters/v3/`) and, if you set a GA4 property ID, the Analytics Data API (` https://analyticsdata.googleapis.com/`). Google receives the OAuth grant and read- only Search Console / Analytics queries for the account you authorize. * Search Console API: [https://developers.google.com/webmaster-tools](https://developers.google.com/webmaster-tools) * Analytics Data API: [https://developers.google.com/analytics/devguides/reporting/data/v1](https://developers.google.com/analytics/devguides/reporting/data/v1) * Terms: [https://policies.google.com/terms](https://policies.google.com/terms) * Privacy: [https://policies.google.com/privacy](https://policies.google.com/privacy) #### IndexNow When IndexNow is enabled, this site posts published URLs to `https://api.indexnow. org/indexnow`. IndexNow (Bing / Yandex) receives the URL list and your key location. Google does not use IndexNow. * Service: [https://www.indexnow.org/](https://www.indexnow.org/) * Terms / privacy: [https://www.bing.com/indexnow/getstarted](https://www.bing.com/indexnow/getstarted) ### License FLEX SMM & SEO is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 2 of the License, or (at your option) any later version. For more details, see https://www.gnu.org/licenses/gpl-2.0.html. ## Installation 1. Upload the `flex-smm-seo` folder to `/wp-content/plugins/`, or install the zip via **Plugins Add New Upload Plugin**. 2. Activate **FLEX SMM & SEO**. 3. Go to **FLEX SMM & SEO Settings**. Set the title template, homepage title and description, and default social image. 4. Choose which post types and taxonomies belong in the sitemap. 5. Optional: paste webmaster verification codes. Submit `/flex-seo-sitemap.xml` in Google Search Console and Bing Webmaster Tools. 6. Optional: open **Insights** to paste a Google Cloud OAuth client and connect Search Console / GA4. 7. If the sitemap 404s, use **Tools Flush rewrite rules**, or save Permalinks once. ## FAQ ### Does this replace Yoast or Rank Math? It covers everyday on-page SEO, social cards, a sitemap, and schema. It does not manage redirects (use Flex Redirects) and does not replace Google Site Kit. ### What about the default WordPress sitemap? FLEX SMM & SEO serves `/flex-seo-sitemap.xml` and turns off the core `/wp-sitemap. xml` sitemap so search engines get one list. noindex and password-protected URLs are omitted. ### Do I have to connect Google? No. Titles, social tags, schema, and the sitemap work without Google. Insights is optional. ### Where do I put the OAuth redirect URI? On **Insights**, copy the Redirect URI into your Google Cloud OAuth web client. It must match exactly, including `https`. ### Does FLEX SMM & SEO send data to FLEX? No. CSS and JavaScript load from this plugin. Remote calls go only to Google or IndexNow after you opt in. ### What happens when I uninstall? Deleting the plugin removes site settings and Google OAuth tokens. Per-post and per-term SEO meta is left in the database. Deactivating alone keeps your data. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “FLEX SMM & SEO” is open source software.
