The short answer
Editorial assessmentKeywords Everywhere compared with SEOTesting
Both are inexpensive tools that make Google's own data more useful, but at different stages. Keywords Everywhere annotates demand while you research; SEOTesting runs controlled tests on your Search Console data to establish whether a change actually worked. Buy Keywords Everywhere to decide what to write and SEOTesting to find out whether writing it helped.
Choose Keywords Everywhere if
Solo marketers, bloggers, ecommerce sellers, YouTubers, and small teams who want ambient search data wherever they already work, and anyone who needs several people looking at keyword data without paying per seat.
Choose SEOTesting if
SEO practitioners, consultants, and in-house teams who already produce content and now need evidence, particularly anyone who has to defend an SEO program to a CFO or a client and is tired of pointing at a line chart and asserting causation.

13 attributes| Attribute | Keywords Everywhere | SEOTesting |
|---|---|---|
| Category | SEO | SEO |
| Starting price | $84 per year (Bronze) (free plan available) | $50 per month (Single Site) (14 days trial) |
| Pricing model | Annual subscriptions bundling a yearly credit allowance and a seat count, metered at one credit per keyword for paid metrics, with a substantial set of features that consume no credits at all. | Flat monthly tiers priced purely on the number of websites, with unlimited users on every plan and month-to-month billing. |
| Free plan | No free tier for paid metrics, but the extension provides keyword suggestions, traffic estimates, Moz link metrics, YouTube tags, hashtag generation, social metrics, and 200-plus AI prompt templates without consuming credits. | No |
| Free trial | No | 14 days, fully functional, no credit card required, up to 30 sites during the trial |
| Best for | Solo marketers, bloggers, ecommerce sellers, YouTubers, and small teams who want ambient search data wherever they already work, and anyone who needs several people looking at keyword data without paying per seat. | SEO practitioners, consultants, and in-house teams who already produce content and now need evidence, particularly anyone who has to defend an SEO program to a CFO or a client and is tired of pointing at a line chart and asserting causation. |
| Setup time | Five minutes. Install the extension for Chrome, Edge, or Firefox, paste in your API key, and the overlay starts working on the next page you load. There is nothing to configure and no project to create. | Under thirty minutes to connect Google Search Console and see reports. Meaningful testing takes longer to start because someone has to design a valid experiment, define page groups, and agree not to change anything else during the window. |
| Learning curve | Effectively none. The tool teaches itself by appearing where you already work, which is the main reason it has more than a million and a half installs despite being a paid product. | Low for the reports, moderate for the testing. The interface is straightforward, but interpreting a test result correctly requires understanding what a control group does and does not prove, and that is a skill, not a setting. |

Strengths and limitations
Keywords Everywhere
Strengths
- The overlay model removes the context switch entirely, which in practice means keyword research actually happens rather than being deferred to a session that never occurs.
- Coverage across more than 20 sites including Amazon, eBay, Etsy, YouTube, and Pinterest, where mainstream SEO tools have little or no data.
- Seat allowances of 1, 3, 10, and 20 across four tiers costing $84 to $1,440 per year, against $40 to $80 per additional seat per month at Ahrefs.
- Credit metering is completely literal at one credit per keyword, with no charges for viewing reports or applying filters.
Limitations
- It is an overlay, not a platform. No site audit, no rank tracking, no projects, no reporting, and no client deliverables of any kind.
- No AI answer visibility tracking. AI Overview presence metrics and prompt templates are useful, but they do not tell you whether ChatGPT or Perplexity cites your brand.
- Annual billing only, so even the cheap entry tier requires paying twelve months up front.
- Volume data is best treated as relative rather than precise, and link metrics come from Moz rather than a proprietary index, so this is not a source for a disputed competitive analysis.
SEOTesting
Strengths
- The only tool in this comparison set that establishes causation rather than correlation, through both time-based forecasting and genuine split tests.
- Archives Google Search Console data past the sixteen-month retention limit, which is quietly one of the most valuable things any GSC tool can do.
- Unlimited users on every plan with pricing based solely on site count, so team size never affects the bill.
- The AI features are grounded in observable data (chatbot-referred clicks, prompt patterns, session tests) rather than in scraped model output presented as certainty.
Limitations
- Useless below a traffic threshold; testing requires enough impressions and clicks for a difference to be statistically distinguishable, and the site never tells you what that floor is.
- Not a content tool at all: no editor, no scoring, no keyword database, no backlink data, so it is always an addition to a stack rather than a consolidation of one.
- Rigor demands discipline. The tool cannot stop a team from shipping six changes at once and then reading the result as if it proved something.
- AI coverage measures referred traffic and prompts, not brand mentions or share of voice inside AI answers, so it does not replace a dedicated AI visibility tracker.
Pricing compared
Keywords Everywhere
Annual subscriptions bundling a yearly credit allowance and a seat count, metered at one credit per keyword for paid metrics, with a substantial set of features that consume no credits at all.
- Bronze$84
- Silver$168
- Gold$480
- Platinum$1,440
Per dollar, this is the cheapest useful search data on the market, and the seat allowance makes it look almost like a mistake. Bronze at $84 a year for 100,000 keyword lookups works out to under a tenth of a cent per keyword; Gold at $480 gives ten people two million lookups between them, which is roughly what one additional Ahrefs seat costs over eight months. The reason it can be this cheap is that it is not a platform: no crawler, no rank tracker, no projects, no reporting, no proprietary link index. What it sells is ambient access to demand data in the places you already work, and it sells it without the metering anxiety that makes larger tools unpleasant. For a solo operator or a small team, it is close to a default purchase alongside whatever else you use.
SEOTesting
Flat monthly tiers priced purely on the number of websites, with unlimited users on every plan and month-to-month billing.
- Single Site$50
- Medium$125
- Large$375
- EnterpriseCustom
At $50 per month for one site, SEOTesting is priced like a niche utility, and per site at the Large tier it drops under $19, which is close to trivial for an agency. The value question is not the price but the fit: it is worth every dollar to a team with enough traffic to run a real test and disciplined enough to change one thing at a time, and worth nothing at all to a site with 300 monthly clicks or a team that ships ten changes in a sprint. The Search Console data archive alone, past Google's sixteen-month window, justifies the entry price for many working SEOs before the testing features are even considered.
Editorial verdict on each
Keywords Everywhere
Keywords Everywhere is a small tool that solves a real problem, which is that keyword research does not happen if you have to go somewhere to do it. Putting search volume, cost per click, and twelve-month trends onto Google, YouTube, Amazon, Etsy, Search Console, and ChatGPT as you browse turns research from a task into a background fact, and at $84 per year for 100,000 lookups the cost is close to irrelevant. The seat allowances make it stranger still: three people for $168 a year, ten for $480, against $40 to $80 per additional seat per month at the big suites. The 2026 MCP integration, which lets AI assistants query live keyword data rather than inventing it, is genuinely ahead of what a tool this cheap ought to ship. Understand what it is not: no crawler, no tracker, no reporting, and no AI citation tracking despite the AI branding. Buy it as a permanent companion to whatever else you run, not as a replacement for it.

SEOTesting is the most intellectually honest product in this category and the one most likely to change how a team works rather than just what it produces. Everything else here helps you make content; this tells you whether the content did anything. Split testing on a live site, a Search Console archive that outlives Google's own retention, unlimited users at $50 per month, and AI features that measure observable traffic instead of inventing a share-of-voice metric all point at a team more interested in being right than in being impressive. The constraints are equally clear: you need real traffic, real discipline about changing one thing at a time, and another tool to actually produce the content. Add it to the stack. Do not expect it to be the stack.
