If you want to use Gemini Deep Research for account research, the workflow below takes you from a company name to a cited, pressure-tested brief in about twenty minutes, most of them Gemini's. Google describes Deep Research as "an agentic feature in Gemini that can automatically browse up to hundreds of websites" that returns "multi-page reports in minutes," which is the job you face before a first call. This guide covers the exact clicks, the prompt to paste, how to edit the research plan, and how to turn the report into a call plan.
What Deep Research does, and what it does not
Deep Research differs from a normal Gemini chat in three ways: it plans before it searches, it reads far more pages than you would in a sitting, and it returns a structured report with sources rather than a paragraph. Per Google's help documentation, you can also point it at your own material by uploading files and, if the Google Workspace app is connected to Gemini Apps, selecting Gmail or Drive as sources alongside the web. That matters because the best context on an existing account usually lives in your inbox, not on the company's press page.
What it does not do is know your product, your territory, or which findings are load-bearing for your deal. That is your job; the prompts below make Gemini do the reading while you keep the judgement. Two constraints from the same page: you must be signed in and 18 or over, and daily research requests are limited, with higher allowances on Google AI Pro and Ultra. Google does not publish the numbers.
Step 1: Frame the brief before you press Submit
The report's quality is set almost entirely by the prompt, because Gemini derives its research plan from it. "Research Acme Corp" produces a Wikipedia-shaped summary; a prompt that names the account, your solution category, the roles you sell to, and the decisions you need to make produces a brief. Open gemini.google.com, click Add Files in the text box, choose Deep Research, then paste this in with your details filled in.
Research [ACCOUNT NAME] ([WEBSITE]) as if you were preparing a B2B account executive for a first conversation. Context: I sell [SOLUTION CATEGORY] to [BUYER ROLES] at companies like this one. I do not need a company overview. I need evidence that supports or undermines specific reasons this account might buy in the next two quarters. Organise the report under these headings and keep each to the strongest evidence only: 1. What changed in the last 12 months: leadership moves, funding or earnings, acquisitions, layoffs, product launches, new markets, regulatory events. Date every item. 2. Stated priorities: quotes from executives, job postings, investor materials or public roadmaps that reveal what leadership is trying to fix or grow. 3. The people: names and titles of the likely economic buyer, champion candidates and technical evaluator for [SOLUTION CATEGORY], with a source for each. 4. Current stack and vendors relevant to [SOLUTION CATEGORY], including anything that suggests a contract renewal or a migration. 5. Three buying hypotheses: for each, state the hypothesis, the strongest supporting evidence, the strongest contradicting evidence, and a confidence rating of low, medium or high. 6. Open questions I should ask on the call because the public record does not answer them. Cite a source for every factual claim. Flag anything older than 18 months. Do not pad sections with generic industry commentary.
Notice what the prompt refuses: a company overview, uncited claims, and stale data. Those three instructions separate a report you can act on from one you must re-verify line by line. This is a shortened variant of the full account brief prompt at /prompts/build-a-comprehensive-account-brief-with-deep-research-180054, which adds a seller-perspective section and a stakeholder map.
Step 2: Edit the research plan, then start
After you submit, Gemini does not start browsing immediately. Per Google's documentation, it "will create a research plan for your topic," and you can click Edit plan before clicking Start research. Read it. If it added a company-history or market-size step you did not ask for, remove it; if it skipped the people or vendor section, tell it to prioritise those. Thirty seconds here saves ten minutes of report you will scroll past.
Then click Start research. Google says a report "usually takes about 5-10 minutes," longer for complex topics, and you can leave the chat while it works. Go prep the next account; Gemini notifies you when the report is ready and you click Open to read it.
Step 3: Add the sources only you have
For a net-new logo, the web is enough. For an expansion or renewal it is not, because the most useful evidence is the thread where their VP explained what went wrong with the last rollout. Before you submit, use Sources to include Gmail or Drive if your Workspace app is connected, or click Add Files to attach call notes or the last QBR deck, and add one line to the prompt: "Treat the attached files and my email history with this account as primary evidence, and note where they conflict with what is public." That reconciliation is usually where the real angle hides.
Step 4: Pressure-test the report before you trust it
A Deep Research report reads confidently, which is a feature until it is not. Run this follow-up in the same chat so Gemini has the full report in context.
Act as a skeptical sales manager reviewing the brief above before a first call with [ACCOUNT NAME]. 1. List every claim in the report that rests on a single source, and rate how much I should trust it. 2. For each of the three buying hypotheses, write the one question a sharp prospect would ask that would expose the hypothesis as weak. 3. Identify anything in the report that is actually an assumption dressed as a fact. 4. Tell me which hypothesis you would open the call with and why, in three sentences.
Then open the cited source for any name, number, or date you plan to say out loud on the call. Deep Research reduces the reading; it does not remove the responsibility. For the four-block structure a good brief should end in, see the 15-minute account research brief at /blog-posts/15-minute-account-research-brief-ai-workflow.
Step 5: Turn the report into a call plan
Export the report to Google Docs so it lives with the account, then ask for the artefact you actually need: "From the brief and the review above, write a one-page pre-call plan with the opening hypothesis, three discovery questions tied to evidence, two risks to my hypothesis, and the single thing I need to learn to know whether this deal is real." That page, not the twelve-page report, goes into your CRM notes. Save the first prompt once if you run it weekly; the Gemini prompts for sales guide at /blog-posts/gemini-prompts-for-sales covers where to keep reusable prompts and how Gemini behaves inside Gmail, Docs and Meet.
If your company runs ChatGPT instead, the equivalent capability sits inside ChatGPT Work and Codex; see /ai-news/chatgpt-deep-research-work-codex-connected-apps. The prompts above transfer with almost no edits.
Common mistakes
Asking for an overview. "Tell me about Acme" gets you the About page in more words. Ask for evidence for and against specific reasons to buy.
Skipping the plan. The default plan gets you a longer report, not a better one.
Treating citations as verification. A cited claim is a claim with a link. Open it for anything you will repeat to a prospect.
Spending runs on accounts that are not real. Daily requests are limited on every plan. Run Deep Research on booked meetings, and use the lighter page-level workflow at /blog-posts/in-browser-ai-sales-research for quick checks on the rest.
Frequently asked questions
Is Gemini Deep Research free to use for account research?
Google's documentation says Deep Research is available to signed-in users aged 18 and over, with daily research request limits that are higher for Google AI Pro and Ultra subscribers, who can also generate reports using the Pro model. Google does not publish the exact numbers, so check your plan's limits inside Gemini.
How long does a Deep Research report take?
Google states reports usually take about 5 to 10 minutes because Gemini analyses many sources, and complex reports can take longer. You can leave the chat and return when notified, so the real cost to you is the two minutes spent writing the prompt and editing the plan.
Can Deep Research use my emails and files about an account?
Yes, with a condition. Per Google, you can upload files or images with your prompt, and you can select Gmail or Drive as sources only if the Google Workspace app is connected to Gemini Apps. For existing accounts that is the most valuable option in the workflow.
