| Keyword | Volume/mo | KD | CPC | Read |
|---|---|---|---|---|
| ★ chrome extension builder | 720 | 10 | $16.34 | The clearest FALSE SIGNAL in this archive: KD 10 looks like free real estate — until you open the SERP. Page 1: Manus (1.6M ratings) at #2, PlugThis (this report's own trigger product) at #3, Kromio at #5, plus FOUR Google properties. KD measures the backlink weakness of blog incumbents; it says nothing about a product slot occupied by funded startups. Also -45% yearly. |
| ai chrome extension builder | 20 | — | $26.99 | Codex's head word: 20/mo. The third 'AI-vocabulary not formed yet' case this week (after ai-workplace-surveillance and the podcast cleanup family). Users searching this category don't add 'AI' — the incumbents already made AI the default. |
| how to make a chrome extension | 1,000 | 16 | $12.47 | The tutorial lane: biggest volume in the cluster, KD 16 — but the SERP belongs to developer.chrome.com, Google Codelabs, and YouTube, and it's declining -45% yearly like everything else here. A content play against Google's own docs on Google's own platform. |
| manifest v3 | 880 | 32 | — | The macro story in one number: 1,900/mo a year ago → 880 now (-45%). The Manifest V3 migration wave — the event that made this category searchable — has passed. The whole cluster is on the downslope of that wave. |
| publish chrome extension (+ how to) | 300 | 29 | — | Codex's differentiation wedge (launch/listing/compliance checks) measured: `publish chrome extension` 210 + `how to publish` 90, KD 29 (Google docs hold it). The wedge-specific vocabulary — listing generator, publish checklist, privacy policy generator, review time — is 10/mo each. The differentiation exists as a feature; it does not exist as search demand. |
| chrome extension maker / generator / ideas | 120 | 24 | $12.53 | The remaining tail, for the record: maker 50/mo KD 19, generator 30/mo KD 24, ideas 40/mo — all declining. No hidden lane here. |
SERP breakdown: chrome extension builder (Google US, measured 2026-07-19)
| # | Result | What it is |
|---|---|---|
| 1 | developer.chrome.com | Google's official getting-started docs |
| 2 | manus.im | Manus's dedicated playbook page — a 1.6M-rating AI-agent giant squatting this exact term |
| 3 | plugthis.ai | The very product that triggered this report's topic, already at #3 |
| 4 | chromewebstore.google.com | Builder.io extension listing |
| 5 | kromio.ai | A third AI extension builder ('free to start' subscription) |
| 6 | Reddit r/chrome_extensions | A developer's AI-builder launch thread (70+ comments, 1yr old) |
| 7 | codelabs.developers.google.com | Google's official Gemini tutorial (Mar 2026) |
| 8 | YouTube | Emergent extension-building tutorial (9.3K views) |
| 9 | ply.io | A team-tools vendor blog |
| 10 | chromewebstore.google.com | Another Web Store listing |
| Related | 8 items | AI, free, no-code variants — the market already assumes these tools exist |
Three key findings: (1) the product slot is triple-occupied by funded players (Manus/PlugThis/Kromio at #2/#3/#5) — the exact inverse of the Roblox day (07-17), where the planner slot was empty; here there is no empty slot at all; (2) Google properties hold 4 of 10 positions (docs + Codelabs + Web Store ×2) — the platform owner is personally teaching this; (3) no AI Overview — the only good news. An 8-hour MVP against Manus's playbook and PlugThis's head start has no winning move.
Verdict: ⚪ double-weak — the words have volume you can't capture, and the differentiation has features nobody searches for. This report carries a unique provenance: the initial DECISION (ruleset v2) rated it 🟢 83; after measurement produced the evidence below, the upstream evaluator re-rated it 🟡 67 under the new v3 rules (absolute ratings + SERP-occupation checks) — the pipeline's first public self-correction since the measurement-calibration loop went live. The 16-point drop is the price of one fact: the SERP slot is taken.
manifest v3 fell from 1,900 to 880 — the migration wave (this category's demand engine) has passed. Contrast 07-17's Roblox: that cluster ran +156% to +376% with the catalyst ahead (July 28); this cluster's catalyst is behind it.ai meeting consent. Building a site for differentiation nobody searches means betting all discovery on social distribution, to an audience that already knows Manus and PlugThis.how to publish tutorial tail (300/mo, KD 29). 6-month organic projection: 50-200 visits/mo, the archive's lowest.Target User
