Comparison — Updated March 2026

KeySEO vs Keywords Everywhere

Q: Is KeySEO better than Keywords Everywhere for keyword research?

It depends on how you research keywords. KeySEO is a dedicated keyword research web app — enter a keyword and get exact search volume, keyword difficulty (0-100), CPC, competition, related keywords, and AI/LLM visibility checking. Keywords Everywhere is a browser extension that overlays keyword data directly in Google search results, YouTube, Amazon, and other websites as you browse. If you do focused research sessions (batch keyword discovery, competitor gap analysis), KeySEO is more efficient. If you want passive keyword data while you browse, Keywords Everywhere is more convenient. Many professionals use both.

Q: How does pricing compare between KeySEO and Keywords Everywhere?

KeySEO offers a free plan (5 lookups/day), Starter ($9/mo, 100/day), and Pro ($29/mo, unlimited). Keywords Everywhere uses a credit system: Bronze ($1.50/mo, 15,000 credits), Silver ($5/mo, 50,000 credits), Gold ($10/mo, 100,000 credits), and Platinum ($50/mo, 500,000 credits). Each keyword lookup costs 1 credit, so Bronze covers about 500 keywords/day if spread evenly. For heavy research, KeySEO Pro ($29/mo unlimited) is cheaper than Keywords Everywhere Gold ($10/mo, 100,000 monthly cap). For light, casual browsing, Keywords Everywhere Bronze ($1.50/mo) is the cheapest option available.

Q: What does Keywords Everywhere offer that KeySEO does not?

Keywords Everywhere integrates directly into your browser. Key features KeySEO lacks: in-SERP keyword data overlay (volume, CPC, competition shown right on Google results), YouTube/Amazon/Bing search data inline, People Also Search For and related keyword widgets on Google, historical trend charts on search pages, competitor traffic estimation, page-level metrics (word count, links, domain age) shown for each SERP result, and multi-platform coverage (data appears on 15+ websites automatically). Its browser-native approach means zero context-switching.

Q: What does KeySEO offer that Keywords Everywhere does not?

KeySEO provides features beyond Keywords Everywhere: keyword difficulty scoring (0-100 KD — KE only has competition, not difficulty), AI/LLM visibility checking (see how your brand appears in ChatGPT and Gemini), dedicated research interface with batch analysis, related keyword discovery with full metrics, exact search volumes from DataForSEO (not estimated), no credit burn on casual browsing, free plan with no credit card required, and focused analysis without browser extension dependency. KeySEO is platform-independent — works on any browser, any device, no installation needed.

Q: Can I use KeySEO and Keywords Everywhere together?

Absolutely — they complement each other perfectly. Use Keywords Everywhere Bronze or Silver ($1.50-5/mo) for passive keyword discovery while browsing (spot opportunities in SERPs, YouTube, Amazon). Then use KeySEO Pro ($29/mo) for deep research sessions: difficulty analysis, AI visibility checking, bulk related keyword discovery. Combined cost: $30.50-34/mo — still cheaper than Ahrefs ($129/mo) or SEMrush ($139/mo). This 'Power Combo' gives you both passive browsing intelligence and focused research depth.

Q: Which tool has more accurate keyword data?

Both tools source data from reputable providers but use different methods. KeySEO pulls from DataForSEO, which aggregates Google Keyword Planner data with clickstream enrichment — giving exact (not ranged) search volumes. Keywords Everywhere also uses a combination of sources including Google Keyword Planner data and its own clickstream panel. For popular keywords (1,000+ monthly searches), both are generally accurate. For long-tail keywords (under 100 searches), both can vary since low-volume data is inherently noisy. KeySEO tends to show more conservative estimates while Keywords Everywhere can show slightly inflated numbers for trending terms.

Q: Does Keywords Everywhere have AI search features like KeySEO?

Keywords Everywhere has added some AI-adjacent features: it shows ChatGPT-related keyword suggestions and has an AI writing assistant. However, it does NOT have an LLM Visibility Checker — the ability to see how AI models like ChatGPT and Gemini perceive your brand. KeySEO lets you enter your domain and brand name, then checks whether ChatGPT and Gemini mention you for relevant queries. This Generative Engine Optimization (GEO) capability is unique to KeySEO among budget keyword tools.

Q: Should I switch from Keywords Everywhere to KeySEO?

If your primary use case is browsing-while-researching (seeing keyword data on Google, YouTube, Amazon as you browse), don't switch — that is Keywords Everywhere's core strength and KeySEO cannot replicate it. If your primary need is dedicated keyword research sessions (deep-diving into keyword difficulty, finding related terms, checking AI visibility), KeySEO is the better tool. For most SEO professionals, the answer is 'use both' — Keywords Everywhere for passive intelligence ($1.50-5/mo) and KeySEO for active research ($0-29/mo). Combined, they cost less than any enterprise SEO tool.

KeySEO wins: 10 — Keywords Everywhere wins: 7 — Draw: 5

Pricing: Credits vs Unlimited

The fundamental pricing difference: Keywords Everywhere charges per credit (1 credit = 1 keyword lookup), while KeySEO offers unlimited lookups on its Pro plan. This creates dramatically different economics depending on your research volume.

KeySEO Pricing

Free$0/mo
Starter$9/mo
100 lookups/day = ~3,000/mo
Pro$29/mo
Unlimited lookups

Cost per keyword at scale: $0.00 (Pro unlimited). No credit anxiety — research freely without watching a meter.

Keywords Everywhere Pricing

Bronze$1.50/mo
15,000 credits/year (~1,250/mo)
Silver$5/mo
50,000 credits/year (~4,167/mo)
Gold$10/mo
100,000 credits/year (~8,333/mo)
Platinum$50/mo
500,000 credits/year (~41,667/mo)

Credits burn on every Google search when the extension is active. Heavy browsing can deplete credits faster than expected.

The Credit Anxiety Problem

Keywords Everywhere's credit system creates a subtle psychological friction: every Google search you make while the extension is active consumes credits. Professional SEOs report disabling the extension during casual browsing to conserve credits, then re-enabling it for research sessions. This defeats the purpose of a browser extension — the always-on convenience.

At Bronze tier ($1.50/mo), you get roughly 1,250 keywords per month. If you do 50 Google searches daily with the extension active, you'll burn through credits in about 25 days — leaving the last week of the month dark. Power users need Gold ($10/mo) or Platinum ($50/mo) to avoid this trap.

KeySEO Pro ($29/mo) eliminates this entirely. Research as much as you want, as often as you want. No meter, no anxiety, no rationing.

Web App vs Browser Extension: Two Philosophies

This comparison is fundamentally about two different approaches to keyword research. Understanding the philosophy behind each tool helps you choose the right one — or use both.

KeySEO: The Research Lab

KeySEO is built for focused research sessions. You sit down, enter keywords, analyze metrics, discover related terms, check difficulty, assess AI visibility — then make decisions. It's a destination tool: you go to it when you need answers.

→ Workflow: Intentional. Open KeySEO → research → decide → close.
→ Best for: Content planning sessions, competitor gap analysis, keyword difficulty assessment, AI visibility audits.
→ Strength: Depth. Full metrics, related keywords, difficulty scoring, LLM visibility.
→ Limitation: Context-switch required. You leave your current task to research.

Keywords Everywhere: The Ambient Sensor

Keywords Everywhere turns your browser into a keyword research tool. Every Google search, every YouTube video, every Amazon product page shows keyword data. It's not a destination — it's a layer on top of your existing workflow.

→ Workflow: Passive. Browse normally → see data → spot opportunities.
→ Best for: Spotting keyword opportunities during regular browsing, quick volume checks, SERP analysis, multi-platform research.
→ Strength: Convenience. Zero context-switching. Data is always there.
→ Limitation: Shallow. No keyword difficulty, no AI visibility, credit consumption on every search.

Keyword Difficulty: The Gap That Matters

The single biggest feature gap between these tools is keyword difficulty scoring. KeySEO provides a 0-100 KD score for every keyword, telling you how hard it'll be to rank on page 1. Keywords Everywhere shows Google Ads competition (0-1 scale) — which measures paid advertising competitiveness, NOT organic ranking difficulty.

Why this matters: A keyword can have low competition (few advertisers bidding on it) but high difficulty (strong organic competitors with authoritative domains). Without KD, you're flying blind — you might target a keyword with low competition but rank 50+ because every page 1 result has DR 80+ and thousands of backlinks.

Real-World Example

The keyword "best CRM software" has a Google Ads competition score of ~0.85 (high). But it also has a keyword difficulty of ~85/100 (very hard). Both metrics point the same direction here.

Now consider "incident postmortem template": competition is ~0.15 (low — few advertisers), but keyword difficulty might be 35-45 (medium — decent authority sites ranking). Keywords Everywhere shows this as "low competition" and you might think it's easy. KeySEO shows KD 35-45 and tells you it's achievable but requires quality content and some authority.

For SEO professionals, keyword difficulty is the metric that matters. For PPC marketers, competition is the metric that matters. Know which game you're playing.

AI Visibility: The 2026 Edge

With ChatGPT reaching 200M+ weekly active users and Google AI Overviews covering 25%+ of searches, AI visibility is no longer optional. KeySEO's LLM Visibility Checker lets you see exactly how ChatGPT and Gemini reference your brand — a capability Keywords Everywhere doesn't offer.

This matters for forward-looking SEO: if AI models don't know your brand exists, you're invisible to a growing percentage of how people discover information. Generative Engine Optimization (GEO) is emerging as a critical discipline, and KeySEO is one of the first budget tools to include GEO checking.

Keywords Everywhere has added some AI-adjacent features (ChatGPT keyword suggestions, AI writing assistant), but these are content creation aids — not visibility tracking tools. There's a significant difference between "use AI to write content" and "check if AI knows your brand."

Who Should Use What? 6 Real-World Scenarios

1. Freelance Content Writer

→ Keywords Everywhere

Writes blog posts for clients. Needs to quickly check keyword viability before pitching topics.

Recommendation: Keywords Everywhere Bronze ($1.50/mo)

Quick volume checks during research browsing. Low volume, casual use. Credit anxiety won't be an issue at <50 searches/day.

Recommendation: KeySEO Pro ($29/mo)

Unlimited lookups across all clients. KD scoring essential for client recommendations. AI visibility checking is a differentiator in pitches. One subscription, unlimited value.

3. E-commerce Product Manager

→ Keywords Everywhere

Optimizes product listings on both their website and Amazon. Needs cross-platform keyword data.

Recommendation: Keywords Everywhere Gold ($10/mo)

Amazon inline keyword data is unique and valuable. Seeing keyword data while browsing competitor products is the workflow fit. Google + Amazon coverage in one tool.

4. Startup Founder (Bootstrapped)

→ KeySEO

Building content strategy from scratch. Needs to find low-difficulty keywords they can actually rank for.

Recommendation: KeySEO Pro ($29/mo)

Keyword difficulty is THE metric for startups — you can't waste months targeting impossible keywords. AI visibility matters for early brand building. Unlimited lookups for deep research sessions.

5. YouTube Creator

→ Use Both

Researches keywords for video titles, tags, and descriptions. Needs YouTube-specific data.

Recommendation: Both ($30.50-34/mo)

Keywords Everywhere for inline YouTube keyword data while browsing. KeySEO for deep keyword difficulty analysis on video topics. The combo gives YouTube-specific browsing intelligence plus difficulty scoring.

6. In-House SEO Manager

→ Use Both

Handles all organic strategy for one company. Needs comprehensive keyword intelligence.

Recommendation: Both ($30.50-34/mo)

Keywords Everywhere for passive SERP intelligence during daily monitoring. KeySEO for quarterly content planning, gap analysis, and AI visibility audits. Together they cost less than any enterprise SEO tool.

The Power Combo: Why Use Both ($30.50-34/mo)

For serious SEO professionals, the question isn't "which one" — it's "how do they work together?"These tools solve different problems with different approaches. Together, they cover your full keyword research workflow at a fraction of enterprise tool pricing.

Hidden Costs & Gotchas

KeySEO Gotchas

⚠No browser integration: You must leave your current tab and visit keyseo.co. No passive data while browsing.
⚠Google data only: No YouTube, Amazon, or Bing-specific search volume. Uses Google as a proxy for demand.
⚠No SERP-level metrics: Can't see competitor page word count, backlink count, or domain authority from search results.
⚠Free plan is limited: 5 lookups/day is enough for testing but not for real work.

Keywords Everywhere Gotchas

⚠Passive credit drain: Every Google search consumes credits whether you need keyword data or not. Casual browsing eats into research budget.
⚠No keyword difficulty: Competition ≠ difficulty. You can't assess organic ranking feasibility.
⚠Desktop-only: Browser extensions don't work on mobile. No keyword research on phone or tablet.
⚠Annual credit reset: Unused credits don't roll over between billing periods. Use-it-or-lose-it.
⚠Extension dependency: If browser updates break the extension (happens occasionally), you have no keyword tool at all until it's fixed.

Competitive Landscape (2026)

KeySEO and Keywords Everywhere occupy different market segments but compete for the same budget-conscious SEO professional. Here's where they sit among alternatives:

Ahrefs

$129-449/mo

Full-suite premium. Massive index, rank tracking, site audit. Overkill if you only need keyword research.

SEMrush

$139-499/mo

Full-suite premium with PPC focus. Most features overall but highest price. Enterprise-grade.

Ubersuggest

$12-40/mo

Budget all-in-one by Neil Patel. Lifetime deal available. Similar price range to both KeySEO and KE but different approach.

Mangools (KWFinder)

$29-79/mo

Clean UI, beginner-friendly. Closest to KeySEO in scope but no AI visibility or free plan.

Surfer SEO

$89-299/mo

Content optimization focused (NLP, SERP analysis). Not a keyword research tool per se.

Google Keyword Planner

Free (with Google Ads account)

Ranged volumes, no difficulty. The baseline that both KeySEO and KE improve upon.

AnswerThePublic

$5-99/mo

Question-focused keyword discovery. Complementary to both tools, not competitive.

SE Ranking

$55-239/mo

Budget all-in-one suite. Broader than KeySEO, cheaper than Ahrefs/SEMrush. Strong rank tracker.

4 Market Trends to Watch

1. AI search visibility: GEO checking becomes table stakes. Tools without it will feel outdated by 2027.
2. Extension fatigue: Browser extensions face increasing friction (Manifest V3, privacy restrictions, mobile-first shift).
3. Credit model pressure: As keyword research volume grows with AI-assisted content, per-credit pricing becomes increasingly expensive.
4. Unbundling accelerates: More SEOs choosing specialized tools (KeySEO + Screaming Frog + RankMath) over enterprise bundles (Ahrefs/SEMrush).
