KeySEO vs Moz Pro
Focused Keyword Research vs Legacy SEO Suite
Moz invented Domain Authority and built one of SEO's most trusted brands — but their keyword research is crippled by query limits (75/mo on Starter!). KeySEO gives you a free lookup tool and plans a whole topic for $29 once. Here's when each tool actually makes sense.
⚡ TL;DR — The Quick Answer
Choose KeySEO If You...
- ✓Need a keyword plan for a project, not another monthly plan
- ✓Want to pay $0, or $29 once, instead of $49-299/mo
- ✓Are a content creator planning blog posts and articles
- ✓Want to check your brand's visibility in AI search (ChatGPT, Gemini)
- ✓Need a free plan with real data — not a 30-day trial
Choose Moz Pro If You...
- ✓Need Domain Authority (DA) and Page Authority (PA) scores
- ✓Run regular site audits with page crawling
- ✓Track keyword rankings across multiple campaigns
- ✓Want MozBar browser extension for on-the-fly metrics
- ✓Need Spam Score to evaluate link quality
💰 Pricing: The Keyword Research Math
Moz's biggest weakness for keyword research is their query limits. Even at $99/mo (Standard), you only get 150 keyword queries per month. That's about 5 queries per day. KeySEO's free tool gives you about 5 lookups a day, and a full topic plan is $29 once.
KeySEO Pricing
Moz Pro Pricing
📊 Cost Per Keyword Query
This is the metric that matters for keyword research. How much does each keyword lookup actually cost you?
Moz's Starter plan works out to $0.65 per keyword query. KeySEO's free tool costs nothing per lookup, and the $29 report is priced per topic, not per query.
🔍 Feature-by-Feature Breakdown
An honest look at where each tool wins. We're not going to pretend KeySEO does everything Moz does — it doesn't. But for keyword research, the numbers speak for themselves.
Keyword Research
Winner: KeySEOKeySEO
- ✓About 5 free lookups a day (~150/mo) — double Moz Starter
- ✓Search volume, KD, CPC, and competition data
- ✓Related keywords with full metrics
- ✓12-month search trend visualization
- ✓Country-specific data (US, UK, CA, AU, DE)
- ✓No campaign setup required — instant results
Moz Pro
- ✓Keyword Explorer with volume, difficulty, CTR
- ✓Keyword Suggestions by Topic (AI-powered)
- ✓SERP analysis showing who ranks and why
- ✗Limited to 75-15,000 queries/mo depending on plan
- ✗Keyword lists capped at 25-750 keywords
- ✗No free plan (30-day trial only)
Verdict: Moz's Keyword Explorer is a solid tool — it shows organic CTR estimates and SERP features, which KeySEO doesn't. But the query limits are the dealbreaker. If you're doing serious content planning, 75-150 keyword queries per month (Starter/Standard) is absurdly low. You'd burn through that in a single afternoon of research. KeySEO's free tool gives you about 150 lookups a month, and a full topic plan costs $29 once.
Domain & Link Analysis
Winner: MozKeySEO
- ✗No domain authority metric
- ✗No backlink analysis
- ✗No link tracking
- ✗Not built for link building workflows
Moz Pro
- ✓Domain Authority (DA) — the industry standard metric
- ✓Page Authority (PA) for individual pages
- ✓Spam Score to evaluate link quality
- ✓Backlink analysis (75-70,000 queries/mo)
- ✓Link Tracking Lists for monitoring acquired links
Verdict: This isn't close. Moz literally invented Domain Authority, and it remains the most widely cited domain metric in the SEO industry. If you need DA scores, link analysis, or Spam Score — Moz is the tool. KeySEO doesn't compete here because it's not trying to. Different tools for different jobs.
Site Audit & Technical SEO
Winner: MozKeySEO
- ✗No site audit feature
- ✗No page crawling
- ✗No on-page grader
Moz Pro
- ✓Site crawl: 20K-5M pages depending on plan
- ✓On-page optimization grader
- ✓Performance metrics tracking
- ✓On-demand crawls for quick audits
- ✓Crawl scheduling and re-crawls (Medium+)
Verdict: Another clear Moz win. If you need to find broken links, crawl errors, missing meta tags, duplicate content, or other technical SEO issues — Moz does that. KeySEO is a keyword research tool, not a technical SEO auditor. For technical SEO, pair KeySEO with a free tool like Screaming Frog (up to 500 URLs free) or Google Search Console.
AI Search & Future-Proofing
Winner: KeySEOKeySEO
- ✓LLM Visibility Checker — test if AI recommends your brand
- ✓Checks ChatGPT (GPT-4o) and Google Gemini
- ✓Query variation analysis for reliability
- ✓Visibility scoring (0-100) across providers
- ✓Context extraction — see exactly how AI describes you
Moz Pro
- ✓AI Overviews by Keyword — see which keywords trigger AI snippets
- ✓Brand Authority Score (new AI-era metric)
- ✓AI Visibility tracking (beta, Medium+ plans only)
- ✓Moz AI-powered tools across all plans
Verdict: Both tools are investing in AI search features, but with different approaches. KeySEO's LLM Visibility Checker lets you directly test whether ChatGPT and Gemini recommend your brand — actionable, immediate, available to all users. Moz's AI Overviews tracks which keywords trigger Google's AI snippets, and their AI Visibility feature (beta) is limited to Medium ($179/mo) and Large ($299/mo) plans. KeySEO wins on accessibility — AI features available on every plan vs. locked behind $179+/mo for Moz.
Rank Tracking
Winner: MozKeySEO
- ✗No rank tracking feature
- →Use Google Search Console (free) for rank data
Moz Pro
- ✓50-3,000 tracked keywords depending on plan
- ✓Mobile and desktop ranking data
- ✓Multi-campaign tracking (1-25 sites)
- ✓Rank Checker on-demand queries (200-500/day)
Verdict: Moz wins on rank tracking. If you need to monitor keyword positions over time across multiple sites, Moz includes it in every plan. KeySEO doesn't offer rank tracking — for most users, Google Search Console (free) provides sufficient ranking data. But if you need historical trend charts, competitor ranking comparison, and mobile vs. desktop tracking, Moz has you covered.
Browser Extension
Winner: MozKeySEO
- ✗No browser extension
- →Web app only — works in any browser
Moz Pro
- ✓MozBar Premium — DA/PA overlay on any page
- ✓SERP overlay showing DA scores in Google results
- ✓On-page analysis while browsing
- ✓Included with all paid plans
Verdict: MozBar is genuinely useful — seeing DA scores overlaid on Google search results as you browse is a workflow that many SEOs rely on daily. KeySEO doesn't have a browser extension. If MozBar is a key part of your workflow, that's a real reason to keep Moz.
Competitive Research
DrawKeySEO
- ✓Related keywords reveal competitor gaps
- ✓Keyword difficulty shows competitive landscape
- ✓CPC data reveals commercial intent
- ✓LLM visibility — see if competitors appear in AI results
Moz Pro
- ✓Domain comparison (DA side-by-side)
- ✓Competitive research queries (20-100/mo)
- ✓See competitors' top-ranking keywords
- ✓Domain overview with keyword overlap
Verdict: Different strengths. Moz shows domain-level competitive data (DA comparison, competitor keyword overlap, top-ranking pages). KeySEO shows keyword-level competitive data (difficulty, CPC, related terms) and AI visibility. Moz is better for "who are my competitors and how strong are they?" KeySEO is better for "what keywords should I target and can I compete?"
🎬 Real-World Scenarios
Choosing between tools depends on your situation. Here's who should pick what.
Content Creator / Blogger
You write 2-4 blog posts per week and need to research keywords before each one. You need search volumes, difficulty scores, and related keyword ideas.
Moz Starter's 75 keyword queries/month means you'd run out in 2 weeks. KeySEO's free tool (about 150 lookups a month) and a $29 report per new topic cover it without a subscription.
SEO Agency Managing Clients
You manage 5-10 client sites. Need site audits, rank tracking, DA monitoring, competitor analysis, and keyword research for each client.
Moz Medium for audits, rank tracking, reporting and daily keyword research. A KeySEO report gives each new client topic a ready keyword plan and content calendar.
Startup Founder Building SEO from Scratch
You're bootstrapping. Every dollar counts. Need keyword research to plan your first 50 pages of content and understand your competitive landscape.
5 free lookups/day is enough to research 1-2 keywords daily. Combine with Google Search Console (free) for rank tracking and technical insights. Upgrade when revenue justifies it.
Link Builder / Outreach Specialist
You evaluate link prospects by DA, check for spam signals, and monitor acquired backlinks. Keyword research is secondary.
DA, Spam Score, and MozBar are essential for link building workflows. KeySEO doesn't have link metrics. Moz Standard includes 5,000 backlink queries/month.
E-Commerce Product SEO
You research product keywords, analyze commercial intent via CPC, and plan category/product page content at scale.
One report clusters a category's product keywords with volume, difficulty and CPC to prioritize high-commercial-intent pages. Bulk daily research needs a subscription tool.
In-House SEO at a Medium Company
You need everything: keyword research, technical audits, rank tracking, competitor monitoring, and reporting for stakeholders.
"Everything" includes daily keyword research, and KeySEO has no unlimited plan. Add a $29 KeySEO report when you open a new topic and want the plan written for you.
🤔 The Domain Authority Question
Let's address the elephant in the room. Moz's biggest unique asset is Domain Authority (DA) — the 0-100 metric that's become the industry standard for evaluating domain strength. It's used in outreach templates, link building negotiations, and client reports everywhere.
Why DA Matters
- • Industry-standard metric everyone understands
- • MozBar shows DA on any page as you browse
- • Link prospects are evaluated by DA
- • Client reports and benchmarks often use DA
- • Spam Score helps identify toxic links
Why DA Isn't Everything
- • Google doesn't use DA — it's a third-party metric
- • DA can be manipulated (PBNs, link spam)
- • A DA 30 site can outrank a DA 60 site with better content
- • Keyword difficulty (available in KeySEO) often matters more
- • Google Search Console shows actual performance, not estimates
Bottom line: If DA is central to your workflow (link building, client reporting, outreach), keep Moz. If you're focused on content creation and keyword targeting, keyword difficulty scores (available in KeySEO for free) are more actionable than DA for deciding what to write about.
⚠️ The Moz "Query Tax" Problem
The most frustrating aspect of Moz Pro for keyword research isn't the price — it's the query limits. Let's do the math on what "75 keyword queries per month" actually means:
If you're planning a content calendar, you might research 20-50 keyword ideas in a single session. On Moz Starter, that's your entire month's allocation gone in one afternoon. Even Moz Standard (150/mo at $99/mo) barely covers a week of serious keyword research. If you plan content in bursts, a one-time $29 KeySEO report researches the whole topic for you instead.

📐 Where the Data Comes From
KeySEO's Data Pipeline
Source: A third-party data provider (Ubersuggest) supplies KeySEO's keyword metrics: volume, difficulty, and CPC.
Search Volume: A monthly average volume figure per keyword, from the third-party provider.
Keyword Difficulty: 0-100 score from the third-party provider, reflecting how strong the pages currently ranking in the top 10 are.
CPC: Average cost-per-click figure for the selected country, from the third-party provider.
Refresh Rate: Each lookup queries the provider; how often the underlying numbers refresh is up to the provider.
Moz's Data Pipeline
Source: Moz's own keyword and link index, built with its own web crawler.
Search Volume: Monthly volume figures from Moz's own data pipeline.
Keyword Difficulty: 0-100 score based primarily on DA/PA of top-10 ranking pages. Heavily weighted toward link-based signals because of Moz's strength in link data.
Organic CTR: Unique to Moz — estimates what % of searchers actually click organic results vs. paid ads and SERP features.
Refresh Rate: Moz's link index updates every 3-4 weeks. Keyword data updates monthly.
Each tool uses its own data pipeline, so volumes differ between tools. KD methodologies differ too: Moz weights its difficulty score toward its own link metrics, while KeySEO's comes from its third-party provider. Expect the same keyword to score differently in each.
❓ Frequently Asked Questions
🏆 Final Verdict
Moz is a respected legacy platform that invented Domain Authority. It excels at link analysis, site audits, and rank tracking. But for keyword research, it's hamstrung by severe query limits — 75/mo on Starter ($49/mo) is barely usable.
For Keyword Research
For a one-off plan, KeySEO: $29 once vs. 75-150 queries for $49-99/mo on Moz. For daily, high-volume research, neither — that's Moz Medium or another subscription tool.
For Link & Domain Analysis
Moz wins. DA, PA, Spam Score, and MozBar are unique, industry-standard tools that no one else replicates exactly.
Best Combo
Moz Standard ($99/mo) for link and domain work + a $29 KeySEO report when you start a new topic.
