**SEO ChatGPT Plugins** were a group of third-party extensions for [ChatGPT](/wiki/chatgpt) that handled search engine optimization tasks (keyword research, on-page audits, SERP analysis, content briefs, and link-building research) inside the chat window. They were available through the [ChatGPT plugin store](/wiki/chatgpt_plugins) from the broad rollout to ChatGPT Plus subscribers on May 12, 2023, until [OpenAI](/wiki/openai) wound the plugin program down: new installs and new plugin conversations were disabled on March 19, 2024, and all remaining plugin conversations ended on April 9, 2024 [3]. This page is a historical record. SEO ChatGPT plugins no longer exist; their functions moved to [Custom GPTs](/wiki/custom_gpts) and the [GPT Store](/wiki/gpt_store) (January 2024), then to GPT Actions, and ultimately toward the [Model Context Protocol](/wiki/model_context_protocol) (MCP), the open tool-connection standard that ChatGPT, Claude, and other assistants now share.

SEO was one of the most populated filters in the store, and it overlapped heavily with the broader [marketing](/wiki/marketing_chatgpt_plugins) and [advertising](/wiki/advertising_chatgpt_plugins) 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.

## What were SEO ChatGPT plugins?

SEO ChatGPT plugins were search-marketing tools built on OpenAI's plugin protocol, which OpenAI described at launch as "tools designed specifically for language models with safety as a core principle" that "help ChatGPT access up-to-date information, run computations, or use third-party services" [1]. In practice, an SEO plugin let a marketer ask ChatGPT a natural-language question (for example, find keywords for sustainable garden tools, or audit this URL for a target term) and get back live data from a search-marketing backend (keyword volume, ranking difficulty, SERP features, on-page scores) that the [large language model](/wiki/large_language_model) could not produce on its own.

The plugins were not built or endorsed by OpenAI. They were submitted by independent SEO vendors (WebFX, Bramework, SEO Vendor Co., Sembot, Serpstat, and others), each exposing a slice of its own platform through a plugin manifest plus an OpenAPI specification. ChatGPT acted as the conversational front end; the vendor's API did the data work.

## When did ChatGPT plugins launch?

OpenAI introduced the plugin protocol on March 23, 2023, in alpha, 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 [1][2]. 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. OpenAI announced the broad rollout of plugins to all ChatGPT Plus subscribers on May 12, 2023, and SEO Vendor Co. announced approval of its plugin (originally called SEO GPT, later renamed SEO CORE AI) on May 20, 2023, days after the store opened to all Plus subscribers [4][5].

| Date | Event |
|------|-------|
| March 23, 2023 | OpenAI announces ChatGPT plugins beta with twelve launch partners and three first-party plugins [1]. |
| May 12, 2023 | OpenAI announces broad rollout of plugins to all ChatGPT Plus subscribers. |
| May 20, 2023 | SEO CORE AI (formerly SEO GPT) by SEO Vendor Co. is approved in the plugin store [4]. |
| Mid-to-late 2023 | The plugin store grows past 900 entries, with dozens classified under the SEO filter [13][14]. |
| November 6, 2023 | OpenAI introduces [Custom GPTs](/wiki/custom_gpts) at DevDay, signaling a shift away from the plugin format [15]. |
| January 10, 2024 | The [GPT Store](/wiki/gpt_store) opens publicly, with built-in writing and productivity categories that absorb most SEO use cases [16]. |
| March 19, 2024 | OpenAI disables new plugin installs and prevents starting new conversations that use plugins [3]. |
| April 9, 2024 | All existing plugin conversations end; the plugin platform is fully deprecated [3]. |

By the time the plugin store closed, the SEO surface had migrated to two newer formats: Custom GPTs published in the [GPT Store](/wiki/gpt_store), and standalone web apps that called [GPT-4](/wiki/gpt-4) directly through the OpenAI developer platform.

## What did SEO plugins do?

The SEO-category plugins fell into five practical jobs.

* **Keyword research.** Take a topic or competitor URL and return related keywords with search volume, ranking difficulty, cost-per-click, and SERP feature data. This was the most common feature in the category.
* **On-page audits.** Read a target URL and grade its title tag, meta description, heading hierarchy, body copy, internal links, and structured data, then return a prioritized list of fixes for a target keyword.
* **SERP analysis.** Pull the top organic results for a query, summarize the dominant content angle, identify featured snippets and People Also Ask boxes, and flag content gaps.
* **Content briefs and drafting.** Generate an outline, target keywords, recommended word count, and section-level talking points. Some plugins drafted the post end to end.
* **Link prospecting.** Take a niche or domain and surface guest-post opportunities, broken-link targets, or paid backlink inventory.

Unlike the [advertising](/wiki/advertising_chatgpt_plugins) 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 [12][13][14].

## Which SEO ChatGPT plugins were notable?

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 [7]. |
| Bramework | Bramework | Keyword research with search volume, ranking difficulty, and SERP analysis. Surfaced competitor on-page elements, generated content briefs, and clustered related keywords [6]. |
| 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 [4][5]. |
| Sembot | Sembot | Keyword research with CPC, competitiveness, and impression data; domain visibility tracking; Google Ads performance reporting; conversational access to Google Analytics 4 [9]. |
| 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 [8]. |
| Linkhouse | Linkhouse | Backlink prospecting using a database of websites available for paid placements. Integrated with Ahrefs to score domain authority and identify link gaps [10]. |
| 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 [11]. |

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](/wiki/advertising_chatgpt_plugins) and [marketing](/wiki/marketing_chatgpt_plugins) category articles.

### SEO.app

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.

### SEO Assistant (WebFX)

The SEO Assistant plugin was published by WebFX, a Pennsylvania-based digital marketing agency, under the developer URL `webfx.ai` [7]. 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

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) [6]. 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

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 [4]. 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](/wiki/large_language_model) pre-refined data the model could not invent on its own [4][5].

### Sembot

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 [9]. 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](/wiki/advertising_chatgpt_plugins) categories and was filed under both.

### Linkhouse, Quick Creator, and Serpstat

Linkhouse was a Polish backlink marketplace whose plugin made its inventory queryable through ChatGPT [10]. 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 [11]. It was a frequent pairing with content-generation plugins inside the same conversation.

## How did SEO teams use these plugins?

SEO teams that adopted plugins during the beta tended to chain them in three patterns.

* **Research, then brief.** Start with Bramework, Sembot, or the Serpstat plugin to pull keywords and SERP data, ask SEO Assistant to expand the related-keyword list, then hand the combined output to Bramework or SEO.app to generate a content brief. The brief was passed to a human writer or to the base ChatGPT model in the same conversation.
* **Audit, then fix.** Paste a target URL into SEO CORE AI for an on-page audit, follow up with SEO.app to rewrite the weak sections in line with the audit's recommendations, then ask the base ChatGPT model to draft updated meta tags and structured data.
* **Draft, then optimize.** Use Speedy Marketing or Quick Creator to draft a long-form post from a topic and URL, then run the draft through SEO CORE AI or Bramework for a post-draft audit before publishing.

These workflows depended heavily on [prompt engineering](/wiki/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.

## When were ChatGPT plugins deprecated?

OpenAI began winding the plugin program down once Custom GPTs proved more flexible. The company notified users on March 19, 2024, that, in its words, "you will no longer be able to install new plugins or create new conversations with existing plugins," and that "you will be able to continue existing conversations until April 9, 2024" [3]. OpenAI framed the move as "winding down the ChatGPT plugins beta." After April 9, 2024, the plugin platform (and every SEO plugin on it) stopped functioning entirely [3].

SEO plugins inherited the same constraints that pushed OpenAI to retire the program across every category, plus a few specific to organic search.

* **Three-plugin limit.** ChatGPT initially capped users at three active plugins per conversation, which broke any workflow that needed keyword research, an audit, and a draft together.
* **Stale or hallucinated data.** Several plugins returned search-volume or difficulty figures that were out of date or filled in by the [large language model](/wiki/large_language_model) when the underlying API returned an empty result. Operators had to cross-check numbers in a dedicated tool.
* **No write-back to a CMS.** Most plugins could read a URL but could not push edits to WordPress, Shopify, or any other content-management system. Quick Creator was the exception. The lack of write-back kept SEO plugins as research aids rather than production tools.
* **Discoverability.** With more than 900 plugins in the store and dozens tagged SEO, operators struggled to pick between functionally similar tools [13][14].
* **Strategic shift to GPTs.** Once Custom GPTs and the GPT Store launched, OpenAI consolidated the plugin and assistant experiences into a single surface [15][16]. Most SEO plugin developers either rebuilt as GPTs or moved their workflows behind apps that called [GPT-4](/wiki/gpt-4) through the API.

## What replaced SEO ChatGPT plugins?

After the plugin shutdown on April 9, 2024, the SEO-plugin functions migrated along several tracks, and the underlying tool-connection technology evolved through a clear succession: plugins, then Custom GPTs with GPT Actions, then the cross-vendor Model Context Protocol.

* **Custom GPTs and GPT Actions.** [Custom GPTs](/wiki/custom_gpts) in the [GPT Store](/wiki/gpt_store) replicated nearly all plugin features through the GPT Actions framework, which lets a GPT call external HTTP APIs much as a plugin did. The GPT Store opened on January 10, 2024, by which point users had already created more than three million custom GPTs in the roughly two months since the format was announced [16]. SEO.app, Bramework, SEO Vendor Co., and Sembot all rebuilt as GPTs or hybrid web-plus-GPT products.
* **The Model Context Protocol (MCP).** [MCP](/wiki/model_context_protocol) is an open standard, introduced by Anthropic in November 2024, for connecting AI assistants to external data and tools through one interface (often described as a "USB-C port for AI") [17]. Unlike a GPT Action, which works only inside ChatGPT, an MCP server can serve ChatGPT, Claude, and other clients at once. OpenAI added MCP support to ChatGPT in 2025, making MCP the de facto successor to the plugin and Actions model for connecting external SEO data sources to a chat assistant.
* **Standalone AI SEO platforms.** Vendors such as Surfer SEO, Clearscope, MarketMuse, NeuronWriter, and Frase consolidated keyword research, audits, briefs, and drafting into purpose-built platforms outside ChatGPT.
* **Direct API integrations.** Larger SEO agencies and in-house content teams shifted from end-user plugins to bespoke applications that called the OpenAI API directly. This pattern allowed tighter control over prompts, retrieval, brand-voice tuning, and editorial approval.

## How did SEO relate to the marketing and advertising plugin categories?

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](/wiki/marketing_chatgpt_plugins) | Broader brand and demand-generation work | ChatSpot, Speedy Marketing, Quick Creator |
| [Advertising](/wiki/advertising_chatgpt_plugins) | 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.

## ELI5: what were SEO ChatGPT plugins?

Imagine you ran a website and wanted it to show up higher on Google. For about a year (2023 to 2024), you could add small helper tools to ChatGPT, like apps you snap onto a phone, that knew about Google rankings. You could type "what words should my gardening blog use?" and the helper would look up real search data and tell you. Those helpers were SEO ChatGPT plugins. OpenAI turned them off in April 2024, and the same kind of help now comes from custom GPTs and from a newer plug standard called MCP that works across many AI chatbots, not just ChatGPT.
