SEO ChatGPT Plugins were a group of third-party extensions for ChatGPT that handled search engine optimization tasks: keyword research, on-page audits, SERP analysis, content briefs, and link-building research. They were available through the ChatGPT plugin store from the public rollout to ChatGPT Plus subscribers on May 12, 2023, until OpenAI wound the plugin program down on April 9, 2024. SEO was one of the most populated filters in the store, and it overlapped heavily with the broader marketing and advertising categories: many plugins shipped a single backend that could be filed under any of the three labels, and developers picked the filter where they expected the most installs.
OpenAI introduced the plugin protocol on March 23, 2023, with twelve third-party launch partners (Expedia, FiscalNote, Instacart, Kayak, Klarna, Milo, OpenTable, Shopify, Slack, Speak, Wolfram, and Zapier) and three first-party plugins for browsing, code interpretation, and a retrieval reference implementation. None of the launch cohort were SEO tools, but the open manifest plus OpenAPI design meant that any vendor with a public API could ship a plugin in days rather than months. SEO vendors began submitting plugins almost immediately. SEO Vendor Co. announced approval of its plugin (originally called SEO GPT, later renamed SEO CORE AI) on May 20, 2023, days after the plugin store opened to all ChatGPT Plus subscribers.

By the time the plugin store closed, the SEO surface had migrated to two newer formats: Custom GPTs published in the GPT Store, and standalone web apps that called GPT-4 directly through the OpenAI developer platform.
The SEO-category plugins fell into five practical jobs.
Unlike the advertising category, which had only a handful of strict entries, the SEO category was crowded. Mid-2023 round-ups each named between five and ten SEO-specific plugins, with Bramework, SEO.app, SEO Assistant, SEO CORE AI, and Sembot appearing on nearly every list.
The table below covers plugins verifiably published during the plugins beta within the SEO scope. Each entry was confirmed against the developer's own listing, an archived manifest, or contemporaneous coverage. Plugins primarily classified as content marketing or social media tools are listed in the related-categories section rather than here.
| Plugin | Developer | Function |
|---|---|---|
| SEO.app | SEO.app (Smyth) | SEO content creation and on-page gap analysis. Generated content focused on user-supplied keywords and rewrote existing copy to be search-engine optimized. |
| SEO Assistant | WebFX | Generated search-engine keyword lists for a given topic, with related-term expansion to seed content briefs and outlines. |
| Bramework | Bramework | Keyword research with search volume, ranking difficulty, and SERP analysis. Surfaced competitor on-page elements, generated content briefs, and clustered related keywords. |
| SEO CORE AI | SEO Vendor Co. | URL and keyword analysis. Audited title tags, meta descriptions, headings, and body content; assessed competitor SERPs; flagged technical SEO issues. Originally named SEO GPT before approval. |
| Sembot | Sembot | Keyword research with CPC, competitiveness, and impression data; domain visibility tracking; Google Ads performance reporting; conversational access to Google Analytics 4. |
| Speedy Marketing | SpeedyBrand | SEO-aware blog and social copy generation aimed at Shopify and ecommerce stores. Produced search-optimized long-form drafts from a topic or URL. |
| Linkhouse | Linkhouse | Backlink prospecting using a database of websites available for paid placements. Integrated with Ahrefs to score domain authority and identify link gaps. |
| Quick Creator | Quick Creator | Landing page and blog creation for SEO beginners. Bundled keyword discovery, mobile-responsive templates, multi-language support, and AI-driven hosting. |
| Serpstat SEO Plugin | Serpstat | Pulled live keyword and domain metrics from Serpstat (volume, difficulty, PPC competition, CPC, traffic, visibility, backlink counts) into the chat surface. |
A handful of additional plugins appeared in the same store filter but functioned mostly as paid-media or general analytics tools: PPC - StoreYa.com, Competitor PPC Ads, RoboAd, and ChatSpot. They are covered in the advertising and marketing category articles.
SEO.app, marketed as the first SEO optimization assistant for ChatGPT, was developed by the team behind the SEO.app web platform. The plugin handled two core jobs: generating new content tuned to a target keyword set, and rewriting existing copy to close on-page gaps against ranking competitors. Operators supplied a topic, a keyword list, and optionally a URL to optimize, and the plugin returned drafts that respected user-supplied tone and length.
The SEO Assistant plugin was published by WebFX, a Pennsylvania-based digital marketing agency, under the developer URL webfx.ai. It was deliberately narrow: typing a prompt such as "list me keywords for sustainable garden tools" returned a clean keyword list with related terms suitable for seeding content briefs. The plugin did not return search volume or difficulty by itself, which kept the manifest small and the response fast. Marketers who wanted volume data paired it with Bramework or Sembot in the same conversation, until they hit the three-plugin cap.
Bramework's plugin focused on three workflows: keyword analysis (search volume, ranking difficulty, related terms), SERP analysis (on-page elements of ranking pages for a target keyword), and content-brief generation (titles, objectives, key points, and SEO considerations). The plugin connected to the same backend that powered Bramework's web product and required a Bramework account during install. It was promoted as a way to get keyword and SERP data inside a chat without paying for a full Ahrefs or Semrush subscription.
SEO CORE AI was developed by SEO Vendor Co. The plugin was approved by OpenAI on May 20, 2023, after being submitted under the working name SEO GPT. Once installed, it analyzed any user-supplied URL against a long checklist of on-page optimization elements: title and meta tags, heading hierarchy, body content, internal linking, and basic technical SEO signals. Given a target keyword, the plugin returned a prioritized list of fixes and compared the page against ranking competitors. The developer disclosed in the OpenAI Developer Forum that the plugin was deliberately designed to give the large language model pre-refined data the model could not invent on its own.
Sembot was published by a Polish MarTech company that operates an SEM analytics platform. The plugin gave conversational access to keyword data (CPC, competitiveness, impressions), search visibility across the top 3, top 10, and top 50 SERP positions, Google Ads campaign performance, and Google Analytics 4 reporting. A bundled library of more than fifty pre-built prompts steered the conversation toward specific tasks. The plugin sat at the boundary of the SEO and advertising categories and was filed under both.
Linkhouse was a Polish backlink marketplace whose plugin made its inventory queryable through ChatGPT. Operators specified a target domain, a budget, target language, and currency, and the plugin returned a curated list of websites willing to host paid backlinks, scored against Ahrefs' domain rating. It was one of the few plugins explicitly built around buying links rather than earning them, which made it a polarizing entry in the category.
Quick Creator targeted small businesses and SaaS startups that needed search-optimized landing pages and blogs without dedicated SEO staff. It bundled keyword discovery, mobile-responsive page templates, fifteen-plus language support, custom domain hosting, and built-in analytics. Once a user described the target audience and product, Quick Creator generated a landing page or post and exposed it on a hosted URL.
Serpstat exposed a slice of its established SEO platform through a plugin that pulled live keyword data (up to fifty popular keywords with volume, difficulty, PPC competition, and CPC), domain metrics, and backlink summaries into the chat. It was a frequent pairing with content-generation plugins inside the same conversation.
SEO teams that adopted plugins during the beta tended to chain them in three patterns.
These workflows depended heavily on prompt engineering: the plugin schemas were lean, and most of the value came from how the operator framed the conversation and stitched plugin outputs together across multiple turns.
SEO plugins inherited the same constraints that pushed OpenAI to wind the program down across every category, plus a few specific to organic search.
After the plugin shutdown on April 9, 2024, the SEO-plugin functions migrated along three tracks.
In the plugin store taxonomy, SEO sat next to two closely related categories with significant overlap.
| Category | Scope | Representative plugins |
|---|---|---|
| SEO | Organic search: keyword research, audits, briefs, link prospecting | Bramework, SEO.app, SEO Assistant, SEO CORE AI, Sembot, Linkhouse, Serpstat |
| Marketing | Broader brand and demand-generation work | ChatSpot, Speedy Marketing, Quick Creator |
| Advertising | Paid media: ad copy, PPC research, campaign optimization | PPC - StoreYa.com, Competitor PPC Ads, RoboAd |
Many plugins appeared under more than one filter. Sembot was tagged both SEO and advertising. Speedy Marketing was filed under SEO and content marketing. Bramework was usually classified as SEO but was promoted to PPC teams for keyword research. The fuzzy boundaries are part of why the strict SEO category was the largest of the three: most plugins that touched search either started as SEO tools or aspired to be filed there, where install volume was highest.
