Built by an agency SEO
SEO Stack came out of running client work rather than out of a product roadmap, which is why the first thing it does is keep the data Google throws away, and why the second thing it does is answer the questions that come up in client meetings.

Own it
Warehoused under your account, not theirs
Google gives every Search Console property a rolling sixteen month window, and the account belongs to the client. So the single most valuable asset in an SEO agency, the accumulated search history of everything you have ever worked on, is currently rented, expiring and owned by somebody else.
One client property, three years
Month 36 of 36
Google Search Console
16 months held
A rolling 16 month window. Month 17 deletes month 1.
Warehoused in your account
32 months held
Everything from the day you connected the property, kept.
- Google holds
- 16 mo
- You hold
- 32 mo
- Gone if you had not connected
- 16 mo
Illustrative, on a property connected in month five. The gap between the two rows is history Google has already destroyed, and it is the part you can never get back.
Up to 200 client properties, one account
Thirty on Pro and two hundred on Agency, all warehousing in parallel from the day each one is connected.
Backfill, then accumulate
The import takes whatever Google still holds, and everything after that point is kept permanently rather than rolling off the back.
Every query and every page
No thousand row cap and no sampling, which stops mattering on a small brochure site and matters enormously on a large ecommerce client.
Connect a prospect during the pitch
Warehousing starts on connection rather than on contract, so a property connected during a pitch is already accumulating history before you have signed anything.
Every month you delay connecting a client is a month of their history that Google eventually destroys, and you can never get it back.
Work it
The answers clients pay for, before the meeting
This is the margin section. The analysis you would only ever run for your biggest client, because it takes an afternoon, becomes something you can run for every client on the list, which is a different proposition to saving an hour a month.
Every client on one screen, not thirty tabs
Search Console shows you one property at a time, which is why the question of which client is in trouble this month usually gets answered by the client. With every property warehoused in the same account, the portfolio view is just a query.

Illustrative portfolio. Search Console gives you one property at a time, so the question of which client declined this month has no answer until somebody opens thirty tabs and works it out.
Why traffic dropped, specifically
An agency that can answer this correctly on a panic call is a different category of supplier to one that promises to look into it. Query counting separates the number of things a page is served for from where it ranks for them, and putting both next to the click-through rate is what makes the three causes distinguishable.
Clicks down 31 to 38%. Which one is it?
- Clicks1,8401,140
- Impressions94,20055,600
- Queries served3,4101,910
- Average position6.26.1
- CTR1.95%2.05%
Diagnosis
Google is serving the page for fewer things
Clicks and impressions fall together, the number of distinct queries the page is served for falls with them, and the average position barely moves. Nothing has been outranked, the page has simply narrowed.
What you actually do
A coverage problem rather than a ranking one. The page has lost topical breadth, usually after a rewrite, a consolidation or a core update reassessing what it is about, and the work is content rather than links.
Query Counting- Clicks1,8401,190
- Impressions94,20086,900
- Queries served3,4103,270
- Average position4.19.6
- CTR1.95%1.37%
Diagnosis
You have been pushed down the page
Impressions and query count hold roughly steady, so Google still considers the page relevant for the same things, but the average position has fallen and the click-through rate has collapsed with it. Somebody has outranked you.
What you actually do
A competitive problem. Look at who moved above you and on what, then decide whether the answer is coverage, internal links, authority or all three. The one thing it is not is a content cull.
Winners & Losers- Clicks1,8401,270
- Impressions94,20099,800
- Queries served3,4103,720
- Average position2.82.6
- CTR1.95%1.27%
Diagnosis
Ranking better, being clicked less
The hardest of the three to spot and the one most stacks get wrong. Impressions are up, the query count is up and the average position has improved, and clicks have still fallen, because the answer is now being given above the result.
What you actually do
Nothing is broken, the click is being taken further up the page. The response is AI visibility work rather than ranking work, and telling a client this correctly on a panic call is the difference between a renewal and a review.
AI VisibilityIllustrative figures. On a clicks chart alone these three are indistinguishable, which is why so many panic calls end in the wrong piece of work.
Winners and losers, before you open the deck
The first question in every client meeting is what went up and what went down, and it takes most agencies two exports and a pivot table to answer it. Queries and pages are segmented by direction with month by month click columns, and the AI insight writes the summary of what moved and why it probably moved.
An analyst that has already read every client's data
The AI Assistant sits across the whole warehouse, Search Console and GA4 together, so the questions that normally need a data pull become a sentence. Cannibalisation across the full query set rather than a sample, click forecasting from the property's own historic CTR curves, a click line per subfolder which Search Console cannot build at all, and hybrid questions like which pages rank well and convert badly.
- Cannibalisation across every query, not a sample
- Click forecasting from the client's own CTR curves
- Charts Search Console will not build, i.e. per folder
- GSC and GA4 in the same question
Prove the work
Evidence, not assertion
Churn very rarely happens because the work was bad, it happens because nobody could prove the work caused the result. Annotations log every change your team makes with a date, a scope and a change type, then sit on every chart in the platform alongside Google's own algorithm update markers.
So when a client's traffic falls during a core update you can show that it was not your deployment, and when it rises after your rewrite you can show that it was. AI Experiments take it further and run a real before and after on a content change, a redesign or a link campaign, with a verdict written against the GSC and GA4 data rather than against an opinion.
Build on it
Point your own agents at every client's data
Google's Search Console API caps a response at 50,000 rows and stops at sixteen months. The MCP reads the warehouse instead, so a question that touches ten million rows returns ten million rows, and the aggregation and period comparison happen server side, fast enough to sit inside an agent loop rather than time it out.
Portfolio monitoring at scale
List every property, then loop an agent across all thirty running the checks nobody has time to do by hand, on a schedule, every week.
A Slack or Teams SEO agent
Which folders lost the most clicks year on year across our portfolio, answered in the channel, by an agent reading the warehouse rather than a dashboard somebody has to open.
Reporting that writes its own commentary
From the real numbers rather than from a template with the figures dropped into it, which is the difference between a report a client reads and one they file.
Alerting on combinations dashboards miss
AI visibility, algorithm updates and folder level decay watched together, because the interesting signals are almost always a combination rather than a single threshold.
Claude, ChatGPT, Gemini, Cursor, n8n, Make or your own agents
Keys are per client, nameable, rotatable and revocable
The agencies that win the next few years will not be the ones with the best tool subscriptions, they will be the ones who built something on top of their own client data.
The MCP server and its 23 tools
New revenue
Something new to sell
Every other section on this page saves you money. This one makes it. Clients are already asking whether ChatGPT and Gemini mention them, and most agencies have no data and no answer, which is a genuinely rare position to be able to walk into.
AI Visibility and Prompt Research track visibility score, citations, share of voice and sentiment across the models, with prompt level data showing what actually triggers a mention. So it is an add-on retainer line you can price and defend, reported alongside the search data you already send them rather than as a separate subscription with a separate login.
Delegation & workflow
Give a junior one client, not the client's Search Console
Access is granted per property with read or write permissions, and because the data is warehoused in your account rather than queried live, granting it makes no change to the users on the origin Search Console. No new name appears on the client's property, and nobody has to ask them for permission to add a contractor.
Projects and task management sit on the same data, and a task can be tied to an annotation, so the work log and the performance record become the same thing rather than two systems somebody has to reconcile at the end of the month.
- SEOs, developers, writers and clients, each scoped to what they need
- Full sub-delegation on the Agency plan without touching the origin account
- Tasks that convert into annotations, so delivery and evidence are one record
The economics
What this costs per client
Agency owners think in per-client unit economics, so here is the arithmetic rather than a pitch about value.
Pro
$11.67per client property, per month
$349.99 a month for 30 websites, with 60 months of history on every one of them.
Agency
$3.40per client property, per month
$679.99 a month for 200 websites, with 120+ months of history on every one of them.
| What you are paying for | Typical agency stack | SEO Stack |
|---|---|---|
| Search Console data beyond 16 months | BigQuery project plus engineering time | Included |
| Rank tracking | Separate subscription | Included |
| Client reporting | Separate subscription | Included |
| SEO project management | Separate subscription | Included |
| Content and NLP auditing | Separate subscription | Included |
| AI visibility tracking | Separate subscription | Included |
| API or agent access to client data | Build it yourself | Included |
One subscription, not six
Warehousing, rank tracking, client reporting, project management, content auditing, AI visibility and agent access all sit on the same subscription and the same data. A few things start on Pro, i.e. keyword clouds and project management, and the rest is on every plan.
What it does not replace
This is not a backlink index. Keep Ahrefs or Semrush for link and competitor research, because that is a genuinely different job and anybody telling you one tool does both is selling you something. SEO Stack owns the first-party data layer.
Objections
Before you move a portfolio
Can I add client properties without touching their Search Console account?
You connect a property once through Google's normal authorisation, and from that point everything happens inside SEO Stack. Adding your own team to it afterwards, or giving the client a login of their own, makes no change at all to the users on the origin Search Console account.
What happens to the warehoused data when I offboard a client?
It stays in your account, because it was warehoused under your account rather than theirs. You lose the live connection when the property is disconnected, and you keep everything that accumulated while you had it, which is what turns a two year engagement into a case study you can still show in year four.
Can I give a client read-only access to their own data?
Yes. Team access is set per property with read or write permissions, so a client sees their own property and nothing else, and read-only means they can look at everything without being able to change anything.
Does this replace Ahrefs or Semrush?
No, and it is not trying to. This is the first-party data layer, i.e. your own Search Console and GA4 history, warehoused, analysed and made available to agents. Backlink indexes and competitor keyword databases are a different job and you should keep whichever one you use for it.
Do we get white-labelled client reports?
Not today, so we will not pretend otherwise. What you do get is unlimited export to Sheets, CSV and PDF with no row caps, custom chart exports, and per-property client access so a client can log in and look at their own data through your account rather than through Google's interface.
What happens if we exceed our website count mid-month?
You move up a plan, and the history you have already warehoused comes with you. Nothing is deleted and nothing is re-imported, the allowance simply increases.
Is client data isolated between properties and team members?
Yes. Permissions are set per workspace, and a property somebody has not been granted access to is not listed anywhere in their account. It is not greyed out, it is not visible, it simply is not there.
How long until a newly connected property is usable?
The backfill imports whatever Google still holds, which is normally the previous 16 months, and that is available shortly after you connect. Everything from that day forward accumulates permanently, so the value of the property compounds from the moment it is connected rather than from the moment you first need it.
Does the MCP count against any request limit?
MCP calls are unlimited from the Pro plan, which matters because an agent loop across thirty client properties makes a lot of requests and a metered API would make that unaffordable to run.
Connect your first client. Then the other twenty-nine.
Warehousing starts the moment you connect a property. No Cloud project, no schema, no export job. Connect one client today and by your next reporting cycle you will be holding history Google was going to delete.
