The best Microsoft Copilot plugins for online marketing: SEO, ads and analytics

What a Copilot plugin is in 2026

Microsoft's current definition is broad: "A Microsoft 365 Copilot plugin is an installable package that brings together capabilities for a specific task." A plugin can hold a declarative agent, skills, a Copilot connector or a connection to a remote MCP server, and in the Copilot app you find them under Plugins in the navigation pane, with the Agent Store behind it. For a marketer, three routes matter. Agents and plugins from the Agent Store, which also appear on Microsoft Marketplace under the Microsoft 365 Copilot filter. Federated Copilot connectors, which fetch live data over MCP and can be published by Microsoft or submitted by partners. And Copilot Studio, where you build your own agent and add MCP servers from the Power Platform catalogue, which listed 158 MCP connectors in November 2026, or by URL.

Licensing is where Copilot differs most from ChatGPT and Claude. Microsoft now sells Copilot Chat (Basic), Microsoft 365 Copilot (Basic) and Microsoft 365 Copilot (Premium). Agents that only use public data are included with the Basic licences, agents that use shared tenant data are pay-as-you-go in Copilot Credits, and federated connectors require a Microsoft 365 Copilot licence. In Copilot Studio, every marketing MCP connector in the catalogue is a Premium connector, so building with one needs a Copilot Studio subscription or a Power Platform plan. Microsoft itself says connector licensing "can vary depending on the specific connectors and the actions you want to perform", so check with whoever owns your licences before you promise a client a workflow.

Control sits with the admin. In the Microsoft 365 admin center, under Agents > Settings > Agent and plugin access, there are separate switches for agents and plugins built by Microsoft, by your organisation and by external publishers, and connectors from external publishers stay off until an admin allows them. Tools that create, update or delete data require the user's explicit approval at first. These are features for Microsoft 365 work accounts: the merged Copilot app keeps "work and personal accounts" separate, and I found no Microsoft page that offers third-party marketing plugins on a personal account.

One detail is easy to miss when you judge a listing. Several Marketplace entries that look official are published by Microsoft Corporation rather than by the vendor, among them Ahrefs, Windsor.ai's MCP listing, a HubSpot MCP listing and Mixpanel. Microsoft builds those federated connectors on the vendor's MCP server, so the listing carries Microsoft's privacy statement and Microsoft's choice of tools.

And Google is absent here as well. There is no Google Ads, Google Analytics or Search Console connector from Google on Marketplace, and the Power Platform catalogue of 1,681 connectors has none from anyone. Google's own Analytics and Ads MCP servers exist, but you would have to host one yourself and add it to Copilot Studio by URL. Microsoft's own marketing data is patchy too: Microsoft Advertising has an official MCP server (below), Microsoft Clarity's MCP server only runs locally, Bing Webmaster Tools has none, and the LinkedIn connector publishes articles but has no ads data.

How to judge a Copilot marketing plugin (five questions)

The shortlist at a glance

Routes and publishers as listed on Microsoft Marketplace and Microsoft Learn on 13 November 2026.

SEO

Copilot's SEO shelf is short. Semrush and Ahrefs cover the modelled side, GSC Wizard is the only Search Console connector in Microsoft's catalogues, and the rest are enterprise or specialist tools.

1. GSC Wizard

Good at: answering questions about your own Search Console data inside Microsoft 365: performance, opportunities, indexing and IndexNow, with finished figures instead of row dumps. It passed Microsoft's MCP server certification, has a connector page on Microsoft Learn, and is listed on Marketplace as an app built for Microsoft 365. The certified connector carries 24 tools, 22 of them read-only; the two that write are limited to IndexNow, which is the protocol Bing and other engines use to pick up changed URLs quickly.

Watch for: it is a paid product, and it is mine. The certified set is a subset: GA4, Bing Webmaster, Yandex and Merchant Center data need the manual connection in Copilot Studio, which takes a client you create in GSC Wizard. It is a Premium connector in Copilot Studio, and it does not estimate competitor traffic or backlinks.

Access: a GSC Wizard subscription or trial (from €17/month); the sign-in rejects accounts without one. GSC Wizard on Microsoft Marketplace, and my guide to connecting Search Console to Copilot covers both routes.

2. Semrush

Good at: keyword research and competitive analysis if Semrush is already your platform of record. Semrush publishes the Copilot app itself, and it brings the same keyword, domain and backlink database you use in the interface into Copilot.

Watch for: the data is modelled and the MCP is not free. It needs Semrush One Starter or Pro+, SEO Classic Pro or Guru, or a Business or Advanced plan with an API units package, and every query uses units from a monthly allowance of at least 50,000. Semrush's own MCP page does not list Copilot among its clients, so expect setup help to talk about other assistants.

Access: active Semrush account with API access. Semrush MCP on Marketplace.

3. Ahrefs

Good at: backlinks, referring domains, domain and URL ratings, keyword volumes, organic traffic estimates, competitors, rank tracking, SERP overviews and site audits. It is one of the few SEO tools in Microsoft's own federated connector gallery, so where an admin allows connectors built by Microsoft, it is available without a separate install.

Watch for: the listing is published by Microsoft Corporation under Microsoft's privacy statement, so this is Microsoft's build on Ahrefs' MCP server rather than an Ahrefs app. As a federated connector it needs a Microsoft 365 Copilot licence. The figures are Ahrefs' estimates, and each call costs at least 50 API units from your Ahrefs plan.

Access: Ahrefs Lite plan or higher. Ahrefs on Marketplace.

4. Conductor

Good at: enterprise SEO teams that already run on Conductor. Its agent installs from the Agent Store, works in Microsoft 365 Copilot and Teams, and since August 2026 includes a keyword insights tool alongside its reporting on brand presence in AI answers.

Watch for: it is for Conductor customers only, and Conductor's content tools are not in the Copilot agent yet. In Conductor's design those content tools are the only ones that write anything, and their output stays as a draft in Conductor.

Access: Conductor enterprise account. Conductor's Copilot setup.

5. Similarweb

Good at: the question SEO tools answer badly: how much total traffic a competitor gets, and from which channels. Similarweb documents a step-by-step setup for adding its MCP server to a Copilot Studio agent.

Watch for: there is no Marketplace listing for Copilot, so this is a manual Copilot Studio setup with an API key header, built by someone who can create agents. The data is panel-based estimates, least reliable for small sites, and calls use data credits from an API-only, Business or Enterprise plan.

Access: Similarweb account with API access. Similarweb's Copilot Studio guide.

6. Local Falcon

Good at: local SEO. It brings local search rankings, business locations and visibility reports into Copilot, which suits agencies that report map-pack positions for multi-location clients.

Watch for: like Ahrefs, it is a federated connector that Microsoft built and publishes, so it needs a Microsoft 365 Copilot licence and an admin who allows Microsoft-built connectors. It only knows the grids you have run in Local Falcon.

Access: Local Falcon account. Local Falcon on Marketplace.

Paid ads and marketing data

Nothing on this shelf can change a campaign from Copilot today, which makes it the safest of the three assistants for paid media and the least useful for managing it. Microsoft Advertising is the only ad platform with its own server.

7. Microsoft Advertising

Good at: being official and free. Microsoft Advertising's MCP server became available to advertisers through an open flight in August 2026, and it returns campaign and account data for your Microsoft ads. Microsoft points to agency teams at Stagwell using Copilot agents built on it "to deliver campaign audits in seconds".

Watch for: it is read-only by design ("The tools never modify account data"), so optimisation still happens in the Microsoft Advertising interface. It is not in the connector catalogue either: in Copilot Studio you add it by hand with OAuth set to Manual, after registering an app and client secret in Microsoft Entra, which needs someone with the right Azure permissions.

Access: free with a Microsoft Advertising account. Microsoft's setup guide.

8. Supermetrics

Good at: reporting across ad and analytics platforms inside Teams and Copilot. The Supermetrics Marketing Analyst agent is published by Supermetrics on Marketplace, and the same data is available to Copilot Studio builders through the SuperMCP Premium connector. If you have no Supermetrics account, a 14-day trial is created at first sign-in.

Watch for: in Copilot it only queries data, while Supermetrics' Claude connector can now manage campaigns, so do not assume the two behave the same. Deploying the agent to a tenant needs an AI Admin, Global Admin or Global Reader, and large pulls still come back as many rows for Copilot to add up.

Access: Supermetrics subscription or trial. Supermetrics Marketing Analyst on Marketplace.

9. Windsor.ai

Good at: cross-channel reporting from one connection. Windsor.ai publishes a Premium connector in the Power Platform catalogue that queries marketing and analytics data from more than 300 platforms, including Google Ads, Facebook Ads, LinkedIn Ads, HubSpot, Shopify and TikTok, and it works on Windsor.ai's free plan.

Watch for: in Copilot it is read-only. Microsoft's connector page says "data cannot be written back to connected sources", whereas the same vendor's ChatGPT and Claude connectors can pause campaigns. Responses are also capped at 100,000 characters, about 20,000 tokens, so a broad question can come back cut short; narrow the date range and fields.

Access: Windsor.ai account with at least one connected source, plus Copilot Studio. Windsor.ai connector on Microsoft Learn.

10. Funnel

Good at: reporting for teams that already normalise their marketing data in Funnel. Funnel documents adding its MCP server to a Copilot Studio agent and then publishing that agent to Microsoft 365 Copilot and Teams.

Watch for: it is a manual OAuth setup in Copilot Studio, not a listing, and it needs a Funnel subscription and the owner role. The MCP tools only read.

Access: Funnel subscription. Funnel's Copilot Studio guide.

Product and web analytics

There is no Google Analytics connector from Google, and the GA4 option on Marketplace is a third-party agent (see below). Two analytics platforms are in Microsoft's federated connector gallery.

11. Mixpanel

Good at: product analytics in Copilot: "Analyze, query, and manage your Mixpanel data". For a marketer at a SaaS company, the question of which campaign's signups are still active a month later belongs here rather than in GA4.

Watch for: "manage" means it can write, and the listing is Microsoft-built and needs a Microsoft 365 Copilot licence. Unless your Mixpanel account is a free or Growth account created after 1 August 2026, an organisation admin has to enable MCP in Mixpanel first.

Access: Mixpanel account. Mixpanel on Marketplace.

12. Contentsquare

Good at: what visitors did on the page. Contentsquare publishes its own agent, which connects its experience analytics to Microsoft 365 Copilot over MCP, so a landing-page question can cover how visitors behaved on the page, not only how many arrived.

Watch for: it needs an active Contentsquare Experience Analytics account, which is an enterprise purchase, and like every listing here it has no public reviews yet.

Access: Contentsquare account. Contentsquare on Marketplace.

Three traps with Copilot marketing plugins

Estimates in the same table as measurements

Give an agent GSC Wizard and Ahrefs and ask for "our traffic versus competitors", and you get a table that mixes measured Search Console clicks with Ahrefs' organic estimate, with nothing to say they are different kinds of number. Ask for a source column every time, and never paste a figure into a client deck that you cannot trace to a named plugin and date range.

The licence surprise

A colleague builds a useful agent in Copilot Studio with a Premium connector, shares it, and the people using it do not have the licence it assumes, or their use runs on pay-as-you-go Copilot Credits that nobody budgeted for. Microsoft's own licensing pages leave room for both. Agree with your admin who pays for the agent and which licence its users need before you roll it out to a team.

Answers cut short by response caps

Copilot connectors cap how much data one call may return. Windsor.ai's connector stops at 100,000 characters, and GSC Wizard's certified profile refuses a result over that size rather than send a partial one. A capped answer can still read like a complete one, so ask for narrower date ranges, fewer fields and the row count behind every total.
