Keywords Everywhere vs QuestionDB in 2026: Browser-wide keyword overlay vs question mining for content ideas
Keywords Everywhere puts search volume and CPC on every page you visit for $7 a month. QuestionDB mines Reddit, Quora, and Google PAA for real audience questions, with a free tier and paid plans from $9.99 a month.
Keywords Everywhere
QuestionDB- Keywords Everywhere overlays keyword data on 20+ platforms as you browse, including Amazon, eBay, and Etsy. QuestionDB works as a standalone search tool with no browser extension.
- QuestionDB has a free tier with 5 searches per month. Keywords Everywhere has no free access to paid metrics; only ancillary features like prompt templates and hashtag generators work without an API key.
- QuestionDB mines questions from Reddit, Quora, Google People Also Ask, and People Also Search. Keywords Everywhere does not mine community questions at all; its data comes from search volume, CPC, and competition metrics.
- Keywords Everywhere covers ecommerce platforms directly, including Amazon, eBay, and Etsy autocomplete data. QuestionDB has no ecommerce-specific data source.
- Neither tool offers an API. Keywords Everywhere unlocks API access on its Gold tier at $40/month; QuestionDB does not offer an API at any plan level.
- QuestionDB includes an AI Outline Generator on paid plans that turns a question into a starting content brief. Keywords Everywhere has no outline or brief generation feature.
Keywords Everywhere and QuestionDB approach keyword research from opposite directions. Keywords Everywhere is a browser extension that overlays search volume, CPC, and competition data on Google, YouTube, Amazon, and more than 15 other platforms as you browse, so the research happens passively wherever you already are. QuestionDB works from a single search box: type a seed term and it pulls real questions people have asked on Reddit, Quora, Google People Also Ask, and People Also Search, turning question mining into a standalone research session rather than something layered on top of normal browsing. QuestionDB is cheaper to start, with a genuine free tier and a $9.99 Solo plan, against Keywords Everywhere's $7 Bronze plan that requires payment from day one for any real data. Neither tool has a content editor or writing feature; both stop at research and leave content production to whatever tool you use next.
The tools at a glance
Keywords Everywhere
Turn your browser into a keyword research powerhouse across 20+ platforms
Keywords Everywhere is a Chrome, Firefox, and Edge extension that overlays search volume, CPC, and competition data directly on the pages you already visit, from Google Search and Google Keyword Planner to YouTube, Amazon, eBay, Etsy, Bing, Pinterest, Instagram, and X. There is no separate search box to use; the data just shows up as you browse normally.
Since launching in 2015 it has grown past 1.5 million users, and beyond the core metrics it now includes SEO difficulty scores and bulk keyword analysis on the Silver and Gold tiers, plus AI prompt templates and an MCP integration for teams working ChatGPT, Claude, Gemini, and DeepSeek into their SEO workflow.
What it will not do is mine community discussions or generate content ideas from questions people are actually asking. It is a metrics layer for keywords you already have some sense of, not a discovery tool for topics you have not thought of yet, and its credit system, which expires annually, favors consistent moderate use.

QuestionDB
Find low-competition keywords by mining questions from Reddit, Quora, SERP PAA, and People Also Search
QuestionDB starts from a search box rather than a browsing session: enter a seed keyword and it returns real questions pulled from Reddit threads, Quora answers, Google People Also Ask boxes, and People Also Search results. The output reads like a list of article angles rather than a raw keyword export, which suits content planning built around what people are actually asking.
Paid plans add search volume, keyword difficulty, and CPC data on top of the question set, letting you prioritize which questions are worth writing about instead of just browsing them. The AI Outline Generator then turns a chosen question into a starting content brief, and AI Content Analysis checks existing pages against SERP competitors.
There is no API at any plan, so QuestionDB stays a browser-based, session-driven research tool rather than something you pipe into an automated pipeline. Data depth also thins out on highly competitive topics compared to a metrics-heavy tool like Keywords Everywhere, and it has no ecommerce platform coverage at all.

Which should you choose?
Keywords EverywhereQuestionDBQuestionDBKeywords EverywhereQuestionDBKeywords EverywhereQuestionDBThe overlap between these two is smaller than the shared "keyword research" label suggests. Keywords Everywhere is a metrics overlay for keywords you already have some sense of, spread across ecommerce, video, and search platforms. QuestionDB is a discovery tool for topics you have not thought of yet, pulled straight from what real people are asking in Reddit threads and Quora answers. A content-heavy blog will get more from QuestionDB's question mining; a seller or affiliate site juggling Amazon and Google traffic will get more from Keywords Everywhere's platform breadth.
Bottom line
Pick Keywords Everywhere if your research happens while browsing Google, YouTube, or marketplace listings and you want the numbers to just appear without a separate step, especially if ecommerce platforms are part of your workflow. Pick QuestionDB if you are stuck on what to write about next and want real audience questions from Reddit and Quora rather than autocomplete guesses, and take advantage of the free tier before committing to the $9.99 Solo plan. Running both is realistic for a content-and-commerce operation, since a $7 and a $9.99 monthly subscription is a low bar for covering both directions of keyword research.
Frequently asked questions
Is Keywords Everywhere or QuestionDB better for finding content topics from real questions people ask?
QuestionDB is built specifically for this, pulling questions from Reddit, Quora, Google People Also Ask, and People Also Search into a single searchable database. Keywords Everywhere does not mine community questions at all; its strength is inline metrics like search volume and CPC across the platforms you already browse.
Does QuestionDB or Keywords Everywhere have a free plan?
QuestionDB has a genuine free tier with 5 searches per month, enough to test data quality for your niche before paying. Keywords Everywhere has no free access to its core search volume and CPC data; only secondary features like prompt templates and hashtag generators are free without an API key.
Which tool is better for Amazon or ecommerce keyword research, Keywords Everywhere or QuestionDB?
Keywords Everywhere is the clear choice here since it overlays keyword data directly on Amazon, eBay, and Etsy listings. QuestionDB has no ecommerce platform coverage and focuses entirely on question-based content research from Reddit, Quora, and Google SERP features.
Can QuestionDB replace Keywords Everywhere for general SEO keyword research?
Not fully. QuestionDB covers question-based content ideas well but has no inline browser overlay, no ecommerce platform data, and no bulk keyword analysis, all of which Keywords Everywhere offers on its higher tiers. QuestionDB works better as a companion for content ideation than a full replacement for a metrics-focused tool.
Does either Keywords Everywhere or QuestionDB offer an API for agency workflows?
Keywords Everywhere does, unlocking API access on its Gold tier at $40 a month. QuestionDB does not offer an API at any plan level, including its $69.99 a month Enterprise tier, so it stays a browser-based research tool for agencies that need to automate keyword pulls.
Is QuestionDB worth it for small agencies in 2026 compared to Keywords Everywhere?
QuestionDB is worth it specifically for content ideation work, since its $29.99 a month Business plan covers 400 searches across Reddit and Quora data that Keywords Everywhere simply does not have. But an agency also doing ecommerce or general SEO client work will likely need Keywords Everywhere alongside it rather than instead of it, since the two tools do not overlap much in what they cover.
