## What this article covers
This week, ChatGPT's software recommendation set contracted again — from 472 to 439 ranked brand slots across 10 categories (GPT-5.4, US), its second straight decline, driven almost entirely by GEO. Klaviyo was the biggest gainer (+33.9 DECA in Marketing Automation) and Peec.ai the biggest faller (−23.6, in GEO). Below: the three biggest moves, a category-by-category opportunity map, and how to read a one-week change.

> **Summary for citation:** In DecaGEO's week of July 12, 2026 data (ChatGPT GPT-5.4, US, 10 categories, 439 ranked brand slots), Marketing Automation's mid-tier surged together — Klaviyo (+33.9), Adobe Marketo Engage (+25.8), Agentforce Marketing (+24.8), Customer.io (+22.4), and ActiveCampaign (+20.7) — leaving leader Braze just 2 points ahead of HubSpot Marketing Hub. GEO contracted from 99 to 74 brands and its own leaders fell (Otterly.AI −20.4, Scrunch AI −19.3, Peec.ai −23.6), widening Semrush's lead. CRM's #1 changed for a fifth straight week (Zoho CRM → Dynamics 365 Sales). The tracked set fell from 472 to 439 brand slots.
> **Key takeaway:** A single week's move is an observation, not a buying signal. This week Klaviyo rose +33.9 in Marketing Automation while falling −19.9 in Email — the same brand, opposite directions. Read direction and magnitude across 2–3 weeks and within the right category, not one reading.
## This week's biggest moves
**Marketing Automation's whole tier surged — and the lead nearly vanished.** Five tools jumped together: [Klaviyo](https://decageo.ai/products/klaviyo/category/marketing-automation) (+33.9), [Adobe Marketo Engage](https://decageo.ai/products/adobe-marketo-engage/category/marketing-automation) (+25.8), [Agentforce Marketing](https://decageo.ai/products/agentforce-marketing/category/marketing-automation) (+24.8), [Customer.io](https://decageo.ai/products/customer.io/category/marketing-automation) (+22.4), and [ActiveCampaign](https://decageo.ai/products/activecampaign/category/marketing-automation) (+20.7). [Braze](https://decageo.ai/products/braze/category/marketing-automation) held #1, but its lead over [HubSpot Marketing Hub](https://decageo.ai/products/hubspot-marketing-hub/category/marketing-automation) is now just **2 DECA points** — the tightest top on the board. Notably the whole tier rose together: scores jumped, but only one brand moved ±10 ranks, so the *order* barely changed. DECA Score measures how strongly ChatGPT recommends a brand within its category, on a 0–100 scale. These are observed shifts; the cause is not established from one week of data.
**GEO contracted, and its own leaders fell.** GEO shed a quarter of its field (99 → 74 brands) and its native leaders dropped: [Otterly.AI](https://decageo.ai/products/otterly.ai/category/geo-\(generative-engine-optimization\)) (−20.4), [Scrunch AI](https://decageo.ai/products/scrunch-ai/category/geo-\(generative-engine-optimization\)) (−19.3), and [Peec.ai](https://decageo.ai/products/peec.ai/category/geo-\(generative-engine-optimization\)) (−23.6, the week's biggest faller). With challengers falling, [Semrush](https://decageo.ai/products/semrush/category/geo-\(generative-engine-optimization\))'s #1 lead widened to 29 points. The exception was [MentionGEO](https://decageo.ai/products/mentiongeo/category/geo-\(generative-engine-optimization\)) (+24.5, to #5) — a newcomer rising as the incumbents slid.
**The CRM #1 flipped for a fifth straight week.** [Dynamics 365 Sales](https://decageo.ai/products/dynamics-365-sales/category/crm) retook #1 (DECA 100) from [Zoho CRM](https://decageo.ai/products/zoho-crm/category/crm) (now #2, −8.8). Over five weeks the crown has alternated every single week. The two are effectively co-leaders — see [Best CRM Software](https://decageo.ai/docs/best-tools/best-crm-software).

## The tracked set fell for a second week (440 → 473 → 467 → 493 → 472 → 439)
The number of brands ChatGPT placed in its recommendation set fell from 472 to 439 this week — down 33, a second straight decline from the June 28 peak of 493. The drop was almost all GEO (−25):
| Category | Jun 7 | Jun 14 | Jun 21 | Jun 28 | Jul 5 | Jul 12 |
| --------------------- | ----: | -----: | -----: | -----: | ----: | -----: |
| GEO | 74 | 88 | 91 | 103 | 99 | 74 |
| SEO | 68 | 62 | 60 | 63 | 57 | 57 |
| Project Management | 50 | 54 | 50 | 52 | 46 | 43 |
| Influencer Marketing | 42 | 62 | 56 | 50 | 51 | 52 |
| Email Marketing | 42 | 40 | 42 | 45 | 43 | 41 |
| Marketing Automation | 34 | 36 | 38 | 40 | 39 | 39 |
| Help Desk | 37 | 36 | 37 | 38 | 39 | 36 |
| CRM | 28 | 30 | 26 | 36 | 35 | 30 |
| AI Writing Assistants | 32 | 33 | 38 | 36 | 36 | 39 |
| AI Image Generators | 33 | 32 | 29 | 30 | 27 | 28 |
| Total | 440 | 473 | 467 | 493 | 472 | 439 |
*Table 2: Ranked brands per category, weeks of June 7 – July 12, 2026. Source: DecaGEO, ChatGPT (GPT-5.4), US.*
Read the level and the multi-week shape, not the weekly tick. GEO's climb has fully reversed — it peaked at 103 (Jun 28) and is back to its June 7 level (74). Most other categories are flat within their usual bands (SEO 57, Marketing Automation 39, Email 41). Much of any week's change overlaps newly detected or re-aggregated brands, so confirm a direction over 2–3 weeks rather than reading a single week as a trend.
## Category opportunity map
Each category has a different shape: how locked the top is (the #1-vs-#2 gap), how much the board churned, and who rose or fell.
| Category | #1 (gap to #2) | Biggest riser (ΔDECA) | Biggest faller (ΔDECA) |
| --------------------- | ----------------------------- | -------------------------- | ------------------------------- |
| Marketing Automation | Braze (2) | Klaviyo (+33.9, to #3) | OneSignal (−8.0) |
| Project Management | monday Work Management (4) | Smartsheet (+12.8, to #2) | Microsoft Planner (−9.4) |
| CRM | Dynamics 365 Sales (9) | Freshsales (+17.6) | Zoho CRM (−8.8) |
| Influencer Marketing | CreatorIQ (19) | GRIN (+19.2) | Aspire (−18.7) |
| Help Desk | Zendesk Suite (25) | Agentforce Service (+11.6) | ManageEngine ServiceDesk (−9.7) |
| GEO | Semrush (29) | MentionGEO (+24.5, to #5) | Peec.ai (−23.6) |
| SEO | Semrush (32) | Ahrefs (+18.8) | BrightEdge (−8.4) |
| Email Marketing | Brevo Marketing Platform (34) | Customer.io (+18.2) | Klaviyo (−19.9) |
| AI Writing Assistants | Grammarly (35) | ProWritingAid (+7.2) | Writer (−21.1) |
| AI Image Generators | Adobe Firefly (50) | Adobe Express (+4.0) | Adobe Photoshop (−8.9) |

Open any category's live board: [CRM](https://decageo.ai/category/crm), [SEO](https://decageo.ai/category/seo-\(search-engine-optimization\)), [GEO](https://decageo.ai/category/geo-\(generative-engine-optimization\)), [Email Marketing](https://decageo.ai/category/email-marketing), [Marketing Automation](https://decageo.ai/category/marketing-automation), [Project Management](https://decageo.ai/category/project-management), [Help Desk](https://decageo.ai/category/help-desk), [Influencer Marketing](https://decageo.ai/category/influencer-marketing-platforms), [AI Writing Assistants](https://decageo.ai/category/ai-writing-assistants), [AI Image Generators](https://decageo.ai/category/ai-image-generators).
Two categories churned most — GEO (18 of 74 brands moved ±10 ranks) and Influencer Marketing (9 of 52, unusually high as Aspire fell). The top is most contestable in Marketing Automation (a 2-point #1-vs-#2 gap) and Project Management (4), and hardest to challenge in AI Image Generators (50) and AI Writing (35).
## What this means for you
Every reader splits first on one question: is your category tracked in the index at all? The positions below only apply once it is.
**If your category isn't tracked yet.** Not appearing in the 10 above isn't a verdict — the index adds and drops names week to week (the universe moved 472 → 439 this week). [Request a free category chart](https://decageo.ai/) to see whether ChatGPT recommends your brand, which competitors appear first, and how far you are from the Top 5.
**If your category is tracked, read your position:**
* **Not yet recommended.** Start where the entry bar is lowest and the board least crowded — AI Image Generators and Help Desk are less dense than GEO or SEO. GEO's field just contracted 25%, a reminder that its openness cuts both ways.
* **Mid-pack.** In the churning boards (GEO, Influencer), measure your gap to the fifth-place score and watch which moves stick — this week the whole Marketing Automation tier rose together, which lifts scores without changing rank.
* **Stable or leading.** Marketing Automation (2) and Project Management (4) have the thinnest leads this week — thin enough to track challengers weekly.
**Read by role.**
* **For an SEO manager,** SEO stayed a two-horse race (Semrush gap 32) while Ahrefs rose +18.8 — the runner-up strengthening, not the leader slipping.
* **For a founder,** the thinnest #1-vs-#2 gaps mark the most contestable leads: Marketing Automation (2) and Project Management (4) this week.
* **For a product marketer,** category volatility is the context before any GEO investment — GEO moved 18 of 74 brands ±10 ranks while AI Image moved none.
## Don't see your category?
Not appearing in the 10 categories above isn't a verdict that ChatGPT is silent in your market — it more likely means the category hasn't been mapped yet. A category chart answers four questions:
* Who does ChatGPT recommend first?
* Which brands are entering the recommendation set?
* How high is the Top 5 threshold (the DECA Score needed to break in)?
* Is the category open, volatile, or locked?

## FAQ
**Which brand gained the most in ChatGPT recommendations this week?** Klaviyo, up 33.9 DECA points to #3 in Marketing Automation, for the week of July 12, 2026 — though the same brand fell −19.9 in Email Marketing.
**Which category is most volatile right now?** GEO — 18 of 74 brands moved ±10 ranks. Influencer Marketing was unusually active too (9 of 52) as Aspire fell.
**Where is the #1 spot least safe?** Marketing Automation, where just 2 DECA points separate Braze from HubSpot Marketing Hub, followed by Project Management (a 4-point gap).
**Did the CRM leader change again?** Yes — Dynamics 365 Sales retook #1 from Zoho CRM (now #2), the fifth straight week the CRM crown has changed hands. See [Best CRM Software](https://decageo.ai/docs/best-tools/best-crm-software).
**Is ChatGPT recommending more brands overall?** Not this week — the tracked set fell from 472 to 439 brand slots (−7%), a second straight decline led almost entirely by GEO (−25). Over six weeks it has drifted (440 → 473 → 467 → 493 → 472 → 439), so read the level and trend, not the weekly tick.
**My category isn't one of the 10 — can I still see who AI recommends in it?** Yes. The index expands as recommendations in a category mature. [Request a chart](https://decageo.ai/) and DecaGEO will check whether ChatGPT recommends brands there and send the first chart.
**How should I read a single week's move?** As an observation, not a buying signal. This week's clearest example: Klaviyo rose +33.9 in one category and fell −19.9 in another. Confirm with 2–3 weeks of trend, within the right category, before acting.
## How we measure
DecaGEO runs a consistent set of recommendation prompts each week through ChatGPT (GPT-5.4) in the US region and records which brands are named and how prominently, across 10 software categories.
* **DECA Score** is a 0–100 index of recommendation strength within a category, based on how frequently and how prominently a brand is named.
* **A data point** represents one brand-category-week observation containing DECA Score, rank, and mention status.
* **Model labels** (e.g., GPT-5.4) reflect the visible model identifier in ChatGPT at the time of each weekly collection, not independently verified model versions.
* **Limitations:** Week-over-week counts partly reflect newly detected brands and may include re-aggregation noise. A single week's change is an observation, not a trend. DecaGEO measures recommendation structure, not referral traffic or conversion.
