Moz is a professional SEO tool platform, providing keyword research, website audits, backlink analysis and other features. It has a free version (10 keyword queries per day) and a paid version (starting at $99/month)
If you’re doing Google SEO, Moz may be one of the tools you use most—it processes over 500 million keyword search queries every month, with over 2 million users, including 37% of Fortune 500 companies.
The free version allows 10 keyword queries per day, providing search volume and difficulty scores (1-100). The paid version starts at $99/month and provides complete competitor backlink analysis (tracking an average of 12,000 external links per website).
Compared to Ahrefs, Moz’s local SEO features are more prominent, capable of tracking 85% of Google’s “Local Pack” ranking data, which is useful for physical stores.
The tool’s built-in “Page Optimization Score” system checks 12 key indicators, including title length (recommended 50-60 characters) and image ALT tags completeness.
What are Moz’s Features
Moz’s core features focus on SEO optimization, covering keyword research, backlink analysis, website health checks, and other key areas.
According to 2023 data, Moz’s database contains over 500 million keywords, with daily ranking data updates, covering 95% of mainstream search engine markets.
Its Keyword Difficulty Score (1-100 points) achieved 89% accuracy in third-party tests, providing more detailed competitive analysis than free tools (such as Google Keyword Planner).
In website auditing, Moz can detect over 200 technical issues, including loading speed (affecting 40% of user bounce rates), duplicate titles (reducing indexing probability by 15%), etc.
For backlink analysis, free users can view the “Domain Authority” (DA) score of each domain, while paid users can deeply analyze the “Page Authority” (PA) of individual pages, helping judge link quality.
Keyword Research
Moz’s keyword database contains over 1 billion keywords of historical search data. The tool recommends long-tail keyword combinations based on semantic analysis. For example, searching “laptop” will give 32 related suggestions such as “lightweight laptop recommendations 2023” and “gaming laptop value rankings”.
These recommendations are based on actual user search behavior data, with an accuracy rate of 92%.
Tests show that content optimized with tool-recommended long-tail keywords saw an average ranking improvement speed 2.3 weeks faster than regular optimization.
Moz’s keyword tool (Keyword Explorer) provides three core data points:
- Monthly Search Volume (accurate to country/region, e.g., “fitness equipment” has 22,000 monthly searches in the US)
- Keyword Difficulty (KD) (1-100 points, below 30 suitable for beginners, above 50 requires stronger backlink support)
- Click Potential (CPC) (ad competition level, e.g., “insurance” keywords average CPC $5.2)
Practical Application Case:
A client wanted to target “organic coffee beans”. Moz showed this keyword had a monthly search volume of 8,500 with difficulty 42.
But the related keyword “organic coffee bean brands” had a search volume of 3,200 with difficulty only 28. After adjusting the strategy, the keyword ranking improved from page 6 to page 2 within 3 months.
Free Version Limits: 10 queries per day, cannot see specific competitor data.
Website Health Check
Moz’s crawler system uses machine learning technology to identify 187 types of technical SEO issues. Each scan detects core indicators such as page loading speed and structured data completeness, providing specific fix recommendations.
The scan report marks issue priority levels. For example, “urgent fix” issues average 15% impact on indexing rate.
In real cases, after fully fixing issues identified in the report, website average visibility improved by 47%.
Moz’s website crawler (Site Crawl) can scan up to 3,000 pages (unlimited in paid version), with focus on detecting:
- 4XX Error Links (over 5% will affect Google crawl efficiency)
- Duplicate Meta Tags (repeated use of the same title dilutes authority)
- Redirect Chains (over 3 jumps will slow loading by 0.8+ seconds)
Real Problem Discovery:
An e-commerce SEO website had 2,300 404 errors due to discontinued products not being 301 redirected. Natural traffic recovered 17% within 3 weeks after fixing.
Backlink Analysis
Moz’s Link Explorer database tracks over 60 trillion backlink relationships in real-time, with 180 million new link records updated daily.
Its DA scoring algorithm evaluates 58 quality dimensions, including the source domain’s topical authority (40% weight) and the linked page’s content depth, etc.
The advanced filter feature supports precise targeting of quality backlink resources across 15 dimensions including industry relevance (0-100 points) and link placement (body/sidebar).
Data shows backlinks filtered through this tool pass on average 73% more authority value than regular backlinks.
Moz’s Link Explorer database contains over 40 trillion backlink records. Main features:
- Domain Authority (DA): 0-100 points, 30+ is qualified, 60+ is a quality resource
- Backlink Source Distribution (e.g., 45% of a competitor’s backlinks come from industry forums, enabling targeted planning)
- Spam Link Identification (automatically flags low-authority, spam-type links, recommends prioritizing cleanup)
Paid Version Advantages: Can export complete backlink lists (free version only shows top 10), and compare competitor backlink growth trends.
Rank Tracking
Ranking data is collected from 1,500 monitoring points across 28 countries, updated hourly. The system can identify mobile and desktop ranking differences (average gap of 7.3 positions), with regional ranking fluctuation charts.
For local businesses, it can precisely display specific positions in the “3-pack” (position 1 gets 42% of clicks).
Optimizing strategy based on this data can improve core keyword rankings by an average of 19 positions within 8 weeks.
Moz Pro can update keyword rankings daily (free tools typically have 7+ days delay), supporting:
- Local Rankings (e.g., ranking changes for “Beijing dentist” in Google Maps pack)
- Mobile/Desktop Data Separation (mobile rankings may be 5-10 positions lower than desktop)
- Historical Data Comparison (export CSV to analyze 3-month, 6-month trends)
Case: A B2B company found “industrial valves” ranked #9 on mobile but #3 on desktop. After optimizing mobile loading speed, mobile rankings rose to #4 within 2 months.
Page Optimization Recommendations
The scoring system compares 128 optimization features of TOP100 ranking pages, providing actionable recommendations such as “add LSI keywords in the third paragraph” and “optimize image alt attributes”.
Each recommendation includes an effect prediction, e.g., “adding an FAQ module can increase rich snippet display probability by 12%”.
Pages with fully implemented recommendations saw an average CTR improvement of 2.1x, which is 37% higher than industry average.
Moz’s On-Page Grader scores based on 12 criteria (out of 100), including:
- Title Length (recommended 50-60 characters, truncated if over 70)
- H1/H2 Structure (must contain at least 1 H1 and 2 H2s, otherwise penalized)
- Content Relevance (keyword density recommended 1.5-2.5%, higher may be flagged as keyword stuffing)
Test Results: After optimizing following recommendations, a blog page’s click-through rate improved from 2.1% to 3.4%.
Competitor Analysis
Can deeply analyze complete SEO strategies of up to 10 competitors, including their content update frequency (average 2.3 articles per week), backlink acquisition channel distribution, and other core data.
The gap analysis report marks the 3 areas most needing improvement, with specific optimization solutions.
Data shows that after optimizing following the report, 68% of cases achieved traffic growth exceeding competitors within 6 months.
Input competitor domain, Moz can provide:
- Top 50 Ranking Keywords (e.g., competitor brings 1,200 monthly visits through “affordable yoga mat”)
- Backlink Growth Trends (new link quantity and quality in the past 6 months)
- Content Gap Analysis (keywords where competitors rank but you don’t list)
Strategy Adjustment: A travel website found competitors ranked well for “off-the-beaten-path destinations”, so they published 10 long-tail keyword content pieces targeted. Traffic grew 23% in 6 months.
Google Business Profile Optimization
Integrates 87 mainstream local directory platforms. The system can detect NAP (Name, Address, Phone) information differences across major platforms (average of 3.2 inconsistencies per business).
Review monitoring feature can set automatic alerts, immediately notifying when 1-2 star reviews are received.
Statistics show businesses that optimized local information using this tool saw average in-store conversion rate increase of 63%, far exceeding industry average.
For physical stores, Moz Local can:
- Sync Business Information (consistent name, address, phone affects local rankings)
- Manage Customer Reviews (rating increase of 1 star increases click-through rate by 25%)
- Track “Local Pack” Rankings (e.g., top 3 for “Shanghai cafe” gets 65% of traffic in that area)
Actual Results: A restaurant saw in-store traffic increase 40% within 3 months after optimizing with Moz Local.
Moz’s Free Plan
The free version provides 10 keyword queries per day, providing search volume, difficulty scores (1-100) and basic competitive analysis, but cannot view specific ranking data or complete competitor reports.
Website health check feature can scan up to 500 pages, detecting 404 errors, duplicate titles, and other common issues, but detailed fix recommendations require paid plans.
In backlink analysis, free users can view Domain Authority (DA) and basic backlink counts, but cannot export complete lists.
Moz’s free Chrome extension can display real-time SEO data for the current page, including DA, backlink counts, etc.
Free Version Keyword Research
Moz’s free version keyword tool provides basic search volume data, such as querying “personal trainer” showing 12,000 monthly searches, but won’t tell you that the top 10 ranking websites average DA score of 65.
Free users also cannot use the “Keyword Grouping” feature, which in the paid version can automatically categorize 200 related terms, saving 75% of analysis time.
The free version’s Keyword Explorer allows 10 keyword queries per day, providing these core data points:
- Monthly Search Volume (accurate to country/region, e.g., “coffee maker” has 22,000 monthly searches in the US)
- Keyword Difficulty (KD) (1-100 points, below 30 is low competition, suitable for new sites)
- Click Potential (CPC) (ad competition level, e.g., “insurance” keywords average CPC $5.2)
Limits:
- Cannot view specific ranking websites (paid version shows top 10 competitors)
- Reduced number of related keyword suggestions (free version only shows 20, paid version 100+)
Free Version Website Health Check
While limited to 500 pages, free scans can detect 80% of serious technical issues. For example, detecting that a blog has 38 pages missing canonical tags, which Google treats as duplicate content.
After fixing, indexing volume immediately increased by 22%. But the free version doesn’t alert on “potential issues”, such as page loading speed at a critical value (2.9 seconds), which the paid version would mark as “needs attention”.
Free users can use Site Crawl to scan up to 500 pages, detecting:
- 4XX Error Links (over 5% will affect Google crawl efficiency)
- Duplicate Meta Tags (repeated use of the same title reduces page authority)
- Loading Speed Issues (pages over 3 seconds see user bounce rate increase by 40%)
Case:
An e-commerce website using the free version scan found 120 404 errors (mainly discontinued products not having 301 redirects), and indexing volume increased by 18% within 2 weeks after fixing.
Limits:
- Detailed reports (such as priority ranking, historical comparison) require paid plans
- Scan frequency limited (free version once per week, paid version daily)
Free Version Backlink Analysis
The DA score is the most practical feature of the free version. Through comparison, websites with DA above 35 have 3x higher chance of ranking improvement than low-DA websites.
But the free version doesn’t show “backlink quality score”, a paid feature that can identify links that have high DA but are actually spam sites.
The free version’s Link Explorer provides:
- Domain Authority (DA) (0-100 points, 20+ is qualified)
- Total Backlinks (but only shows top 10 backlink sources)
- Anchor Text Distribution (e.g., a site with 60% of backlinks using brand name may lack keyword optimization)
Practical Tips:
Use the free DA tool to filter backlink resources, e.g., only contact websites with DA>20 for link exchanges, avoiding low-quality partnerships.
Limits:
- Cannot view competitor complete backlink strategy
- Historical data comparison (such as backlink growth trends) requires paid plans
Chrome Extension
Real-time data displayed by the extension has about 6-hour delay compared to the web version. When analyzing competitors, you can see their homepage DA value, but internal page data requires paid plans.
Interestingly, the extension marks “anomalous data”, such as a suddenly surging PA value, which may be a signal of purchased links.
Moz’s free Chrome extension features include:
- Current Page DA/PA Score (e.g., a blog article with DA=35, PA=42)
- Backlink Count (accurate to root domain and page level)
- Meta Tag Preview (check if title and description are optimized)
Usage Scenario:
When browsing competitor websites, the extension directly displays their DA=55, backlink count=2,100, allowing preliminary assessment of their SEO level is high.
Free Learning Resources
Moz provides free:
- SEO Beginner’s Guide (50+ page PDF covering basic optimization steps)
- Weekly blog updates (case studies + algorithm change interpretations)
- Community Q&A Forum (1,200+ daily active users, can ask questions or reference historical answers)
Case:
A beginner webmaster learned “title tag optimization” from Moz blog, changed homepage title from “Welcome to My Website” to “Professional Photography Studio in Beijing | Wedding + Commercial Photography”, with traffic increasing 65% within 3 months.
Limitations of Free Plan
The biggest limitation is data depth. For example, the free version shows a keyword difficulty of 50, but the paid version breaks it down: useful content requirements (60%), backlink needs (30%), domain authority (10%).
Tests show strategies developed using complete data are 3-5x more effective than those using free version data.
Compared to the paid version, the free version mainly lacks:
- Rank Tracking (cannot monitor keyword ranking changes)
- Complete Competitor Analysis (cannot see competitor backlink sources and content strategy)
- Local SEO Tools (cannot manage Google Business Profile)
Suitable For:
- Personal blogs or small websites
- SEO beginners just starting out
- Projects needing basic data temporarily
Moz’s Paid Plans
Moz’s paid plans are divided into three tiers (Standard $99/month, Medium $179/month, Large $249/month), mainly targeting users needing deep SEO data.
The core advantages of the paid version are unlimited keyword queries (Standard: 500/month), complete competitor analysis (can view backlink strategies for Top 100 rankings), and daily updated rank tracking (free tools typically have 7+ days delay).
According to Moz’s official data, paid users’ websites saw an average 27% natural traffic growth within 6 months.
For example, a mid-sized e-commerce website using Medium plan found 12 high-quality resources through the backlink analysis tool, with DA improving from 32 to 45 within 3 months.
Paid Plan Feature Comparison

When core keyword rankings drop more than 3 positions, immediate alerts are sent, allowing webmasters to take remedial action within 24 hours, reducing impact by 72%.
The paid version supports:
- Local Rankings and Local Pack Data (e.g., ranking changes for “New York dentist” in local search)
- Device-Specific Statistics (mobile rankings typically 5-10 positions lower than desktop)
- Competitor Comparison (track yourself and 3 competitors’ ranking fluctuations simultaneously)
