Moz is a professional SEO tool platform, offering keyword research, site audit, backlink analysis, and other functions. It has a free version (10 keyword queries per day) and a paid version (starting at $99/month).
If you are doing Google SEO, Moz may be one of the tools you use most often—it processes over 500 million keyword search queries monthly and has over 2 million users, including 37% of Fortune 500 companies.
The free version allows 10 keyword queries daily, providing search volume and difficulty score (1-100). The paid version starts at $99/month and offers complete competitor backlink analysis (tracking an average of 12,000 external links per site).
Compared to Ahrefs, Moz’s local SEO features are more prominent, tracking 85% of Google’s “Local Pack” ranking data, which is useful for physical businesses.
The tool’s built-in “Page Optimization Score” system checks 12 key metrics, including title length (recommended 50-60 characters) and image ALT tag completeness.
What are Moz’s Features?
Moz’s core functions revolve around SEO optimization, covering key areas like keyword research, backlink analysis, and site health checks.
According to 2023 data, Moz’s database contains over 500 million keywords, with daily ranking data updates, covering 95% of the mainstream search engine market.
Its Keyword Difficulty Score (1-100) accuracy reached 89% in third-party tests, providing more detailed competitive analysis than free tools (like Google Keyword Planner).
In terms of site audit, Moz can detect over 200 technical issues, including loading speed (affecting 40% of user bounce rate) and duplicate titles (reducing indexation probability by 15%).
For backlink analysis, free users can view the “Domain Authority” (DA) score for each domain, while paid users can deeply analyze the “Page Authority” (PA) of individual pages, helping to judge link quality.
Keyword Research
Moz’s keyword database contains historical search data for over 1 billion keywords. The tool uses semantic analysis to recommend long-tail keyword combinations. For example, searching for “laptop” suggests 32 related terms like “thin and light laptop recommendations 2023” and “gaming laptop value ranking.”
These recommendations are based on actual user search behavior data, with an accuracy rate of up to 92%.
Tests show that content optimized using the tool-recommended long-tail keywords saw an average ranking increase 2.3 weeks faster than conventional optimization.
Moz’s Keyword Explorer provides three core data points:
- Monthly Search Volume (accurate to country/region, e.g., “gym equipment” has 22,000 monthly searches in the US)
- Keyword Difficulty (KD) (1-100 score; under 30 is suitable for beginners; over 50 requires strong backlink support)
- Click Potential (CPC) (Ad competition, e.g., “insurance” related terms have an average CPC of $5.2)
Practical Application Case:
A client wanted to target “organic coffee beans.” Moz showed 8,500 monthly searches and a difficulty of 42.
However, the related term “organic coffee bean brands” had 3,200 searches and a difficulty of only 28. After adjusting the strategy, the ranking for this term rose from page 6 to page 2 within 3 months.
Free Version Limit: 10 queries per day, cannot see specific competitor data.
Site Health Check
Moz’s crawler system uses machine learning to identify 187 types of technical SEO issues. Each scan checks core metrics like page load speed and structured data integrity, providing specific fix recommendations.
The scan report prioritizes issues. For example, “Urgent Fix” issues impact an average of 15% of the indexation rate.
In actual cases, after completely fixing the issues indicated in the report, websites saw an average visibility improvement of 47%.
Moz’s Site Crawl can scan up to 3,000 pages (unlimited for paid version), focusing on detecting:
- 4XX broken links (if exceeding 5%, it affects Google’s crawl efficiency)
- Duplicate meta tags (multiple occurrences of the same title dilute authority)
- Redirect chains (more than 3 jumps slow down loading speed by over 0.8 seconds)
Real Issue Discovery:
An e-commerce SEO site had 2,300 404 errors due to discontinued products lacking 301 redirects. After fixing this, organic traffic recovered by 17% within 3 weeks.
Backlink Analysis
Moz’s Link Explorer database tracks over 60 trillion backlink relationships in real-time, updating 180 million new link data points daily.
Its DA scoring algorithm evaluates 58 quality dimensions, including the source domain’s topic authority (40% weight) and the linking page’s content depth.
Advanced filtering supports precise targeting of high-quality backlink resources across 15 dimensions, such as industry relevance (0-100 score) and link position (body/sidebar).
Data shows that backlinks filtered by this tool transmit an average authority value 73% higher than ordinary backlinks.
Moz’s Link Explorer database contains over 40 trillion backlink records, with key functions:
- Domain Authority (DA): 0-100 score; above 30 is acceptable, above 60 is a high-quality resource
- Backlink Source Distribution (e.g., 45% of a competitor’s backlinks come from industry forums; allows for targeted strategy)
- Spam Link Identification (automatically flags low-authority, spam-like links, recommended for priority cleanup)
Paid Version Advantage: Can export a complete list of backlinks (free version only shows the top 10) and compare competitors’ backlink growth trends.
Rank Tracking
Ranking data is collected from 1,500 monitoring points in 28 countries globally, updated hourly. The system identifies ranking discrepancies between mobile and PC (average gap of 7.3 positions) and provides regional ranking fluctuation charts.
For local businesses, it can precisely show the position within the “3-pack” (1st position secures 42% of clicks).
Adjusting optimization strategies based on this data can lead to an average increase of 19 positions for core keyword rankings within 8 weeks.
Moz Pro provides daily keyword ranking updates (free tools usually delay by 7+ days), supporting:
- Local Rankings (e.g., ranking changes for “Beijing dentist” in the Google Map Pack)
- Mobile/PC Data Separation (mobile ranking may be 5-10 positions lower than PC)
- Historical Data Comparison (export CSV to analyze 3-month, 6-month trends)
Case: A B2B company found “industrial valves” ranked 9th on mobile but 3rd on PC. After optimizing mobile loading speed, the mobile ranking rose to 4th within 2 months.
On-Page Optimization Suggestions
The scoring system compares 128 key optimization features of TOP 100 ranked pages, providing actionable advice such as “add LSI keywords in the third paragraph” and “optimize image alt attributes.”
Each suggestion comes with an effect prediction, such as “adding an FAQ module can boost rich snippet display chances by 12%.”
Pages that fully implement the suggestions see an average CTR increase of 2.1 times, 37% higher than the industry average.
Moz’s On-Page Grader scores pages based on 12 criteria (max score 100), including:
- Title Length (recommended 50-60 characters, over 70 gets truncated)
- H1/H2 Structure (must contain at least 1 H1 and 2 H2s, otherwise points are deducted)
- Content Relevance (keyword density recommended 1.5-2.5%, too high may be penalized for stuffing)
Test Result: After optimizing according to the suggestions, a blog page’s click-through rate increased from 2.1% to 3.4%.
Competitor Analysis
It allows for deep analysis of up to 10 competitors’ complete SEO strategies, including their content update frequency (average 2.3 articles per week) and backlink acquisition channel distribution.
The gap analysis report highlights the 3 areas most in need of catching up and provides specific optimization plans.
Data shows that cases of traffic growth exceeding competitors after optimizing based on the report accounted for 68% over 6 months.
By inputting a competitor’s domain, Moz can provide:
- Top 50 Ranking Keywords (e.g., a competitor generates 1,200 monthly traffic from “affordable yoga mat”)
- Backlink Growth Trend (number and quality of new links over the past 6 months)
- Content Gap Analysis (a list of keywords where competitors rank but you don’t)
Strategy Adjustment: A travel website noticed a competitor ranked highly for “niche travel destinations,” so it strategically published 10 long-tail content pieces, resulting in a 23% traffic increase over 6 months.
Optimize Google Business Profile
Integrating 87 major local directory platforms, the system detects NAP (Name, Address, Phone) information discrepancies across platforms (average 3.2 inconsistencies per business).
The review monitoring feature sets up automatic alerts, notifying immediately upon receiving 1-2 star reviews.
Statistics show that businesses using this tool to optimize local information saw an average increase of 63% in walk-in conversion rates, significantly above the industry average.
Features for physical stores via Moz Local:
- Synchronize Business Information (consistency of name, address, phone affects local ranking)
- Manage Customer Reviews (a 1-star rating increase boosts click-through rate by 25%)
- Track “Local Pack” Rankings (e.g., the top 3 results for “Shanghai cafe” capture 65% of the area’s traffic)
Tested Effect: A restaurant optimized with Moz Local and saw a 40% increase in walk-in traffic over 3 months.
Moz’s Free Plan
The free version offers 10 keyword queries per day, providing search volume, difficulty score (1-100), and basic competitive analysis, but cannot view specific ranking data or full competitor reports.
The site health check function scans up to 500 pages, detecting common issues like 404 errors and duplicate titles, but detailed fix suggestions require a paid plan.
For backlink analysis, free users can view the domain’s “Domain Authority” (DA) and basic backlink count, but cannot export a complete list.
Moz’s free Chrome extension displays real-time SEO data for the current page, including DA, backlink count, etc.
Free Version Keyword Research
Moz’s free Keyword Explorer provides basic search volume data. For example, a query for “fitness coach” shows 12,000 monthly searches but does not reveal that the top 10 ranking sites have an average DA of 65.
Free users also cannot use the “Keyword Grouping” feature, which in the paid version automatically categorizes 200 related terms, saving 75% of analysis time.
The free Keyword Explorer allows 10 daily keyword queries, providing the following core data:
- Monthly Search Volume (accurate to country/region, e.g., “coffee machine” has 22,000 monthly searches in the US)
- Keyword Difficulty (KD) (1-100 score; under 30 is low competition, suitable for new sites)
- Click Potential (CPC) (Ad competition, e.g., “insurance” related terms have an average CPC of $5.2)
Limitations:
- Cannot view specific ranking sites (paid version shows top 10 competitors)
- Reduced number of related keyword suggestions (free version shows 20, paid version 100+)
Free Version Site Health Check
Although the free scan is limited to 500 pages, it detects 80% of severe technical issues. For example, it identified 38 pages on a blog missing canonical tags, which Google considered duplicate content.
Indexation increased by 22% immediately after fixing. However, the free version does not prompt for “potential issues,” such as page load speed being at a critical threshold (2.9 seconds), which the paid version flags as “needs attention.”
Free users can use Site Crawl to scan up to 500 pages, detecting the following issues:
- 4XX broken links (if exceeding 5%, it affects Google’s crawl efficiency)
- Duplicate meta tags (using the same title multiple times reduces page authority)
- Loading speed issues (pages over 3 seconds see a 40% increase in user bounce rate)
Case:
An e-commerce site used the free scan to find 120 404 errors (mainly discontinued products without 301 redirects). After fixing, indexation increased by 18% within 2 weeks.
Limitations:
- Detailed reports (e.g., priority sorting, historical comparison) require payment
- Limited scan frequency (free version once a week, paid version once a day)
Free Version Backlink Analysis
The DA score is the most practical feature of the free version. Comparison shows that sites with DA above 35 are 3 times more likely to see rank increases than low-DA sites.
However, the free version does not display the “Link Quality Score,” a paid feature that identifies links that, despite having a high DA, originate from spam sites.
The free Link Explorer provides:
- Domain Authority (DA) (0-100 score; above 20 is acceptable)
- Total Backlink Count (but only shows the top 10 backlink sources)
- Anchor Text Distribution (e.g., 60% of a site’s backlinks use brand names, potentially lacking keyword optimization)
Practical Tip:
Use the free DA tool to filter backlink resources, e.g., only contact sites with DA > 20 for link exchange, avoiding low-quality partnerships.
Limitations:
- Cannot view a competitor’s complete backlink strategy
- Historical data comparison (such as backlink growth trend) requires payment
Chrome Extension
The data displayed by the extension is delayed by about 6 hours compared to the web version. When analyzing competitors, you can see their homepage’s DA value, but internal page data requires payment.
Interestingly, the plugin flags “abnormal data,” such as a sudden PA spike, which might signal a purchased link.
Moz’s free Chrome extension features include:
- DA/PA score for the current page (e.g., a blog post has DA=35, PA=42)
- Backlink count (accurate to root domain and page level)
- Meta tag preview (checks if the title and description are optimized)
Usage Scenario:
When browsing a competitor’s site, the plugin instantly shows their DA=55 and backlink count=2,100, providing a preliminary judgment of their high SEO level.
Free Learning Resources
Moz offers free:
- The Beginner’s Guide to SEO (over 50-page PDF, covering basic optimization steps)
- Weekly Blog Updates (case studies + algorithm change interpretation)
- Community Q&A Forum (daily active users 1,200+, allows asking questions or referring to historical answers)
Case:
A novice webmaster learned about “Title Tag Optimization” through the Moz blog, changing the homepage title from “Welcome to my website” to “Beijing Professional Photography Studio | Wedding + Commercial Shoots,” resulting in a 65% traffic increase over 3 months.
Free Plan Limitations
The biggest limitation is data depth. For instance, the free version shows a keyword difficulty of 50, but the paid version breaks it down into: Helpful content requirement (60%), backlink demand (30%), and domain authority (10%).
Tests show that strategies formulated using full data are 3-5 times more effective than those based on free version data.
Compared to the paid version, the free version primarily lacks:
- Rank Tracking (cannot monitor keyword ranking changes)
- Full Competitor Analysis (cannot see competitors’ backlink sources and content strategy)
- Local SEO Tools (cannot manage Google Business Profile)
Suitable Users:
- Individual blogs or small websites
- Beginners just starting SEO
- Projects temporarily needing basic data
Moz’s Paid Plans
Moz’s paid plans are divided into three tiers (Standard $99/month, Medium $179/month, Large $249/month), primarily targeting users who need in-depth SEO data.
The core advantage of the paid version lies in unlimited keyword queries (Standard has 500/month), complete competitor analysis (can view backlink strategies for the Top 100 rankings), and daily updated rank tracking (free tools typically delay by 7+ days).
According to official Moz data, paid users’ websites see an average organic traffic growth of 27% within 6 months.
For example, a medium-sized e-commerce site using the Medium plan found 12 high-quality resources through the backlink analysis tool, boosting its DA from 32 to 45 within 3 months.
Paid Plan Feature Comparison
| Feature | Standard ($99/month) | Medium ($179/month) | Large ($249/month) |
|---|---|---|---|
| Keyword Queries / month | 500 | 1,000 | 5,000 |
| Rank Tracking Keywords | 25 | 50 | 150 |

- Professional SEO agencies or large projects require Large + API access
Paid Version Keyword Research
The paid version offers competitive page analysis, allowing you to view the high-quality content length (industry average is 1,892 words), backlink count (TOP 3 average has 158 backlinks), and other key metrics for the top 10 ranking pages.
The system automatically flags high-value, low-competition keywords, accounting for about 15% of total recommendations, with an average optimization difficulty 37% lower than conventional terms.
Data shows that new sites focusing on optimizing these terms can achieve 2.4 times the traffic growth of ordinary strategies within 6 months.
The paid version unlocks the following features:
- Complete Competitor Keyword Database (view competitor’s top 100 ranking keywords and traffic share)
- Historical Search Trends (analyze a keyword’s change over the past 12 months, e.g., “home fitness” grew 300% during the pandemic)
- Long-Tail Keyword Expansion (system automatically generates 500+ related term suggestions, e.g., “yoga mat” spawns “non-slip yoga mat” “thick yoga mat,” etc.)
Paid Version Site Health Check
The deep scan feature uses machine learning to identify rendering issues (about 23% of technical problems) that traditional tools struggle to find.
The prioritization system is trained on 10 million pages and accurately predicts the impact of each issue on ranking (error rate only ±5%).
The automated monitoring is especially useful, sending alerts within 1 hour when a sudden technical issue (like a mass 404 error) is detected, 95% faster than the free version’s 24-hour response.
The paid Site Crawl provides:
- Unlimited Page Scan (free version limited to 500 pages)
- Priority Sorting (flags the issues with the largest impact on SEO, e.g., “homepage load speed 3.2 seconds, recommended to compress images“)
- Automatic Monitoring (weekly report, alerting to new 404 errors or duplicate content)
Tested Effect:
A news website fixed “200 duplicate Meta descriptions” detected by the paid version, boosting Google indexation by 40%.
Paid Version Backlink Analysis
The advanced filter includes 17 dimensions. The most practical is “link position analysis,” which can filter for backlinks in the first paragraph of the body (these links pass 83% more authority than footer links).
It can also uncover a competitor’s backlink building patterns (e.g., a major industry site consistently acquires links from 3 authoritative media outlets monthly).
Data shows that building backlinks by mimicking these patterns can increase indexation speed by 60%.
Paid users can:
- Export the entire backlink list (free version only shows 10 links)
- Filter links by DA/PA (e.g., only keep resources with DA > 40)
- Track backlink growth trend (chart shows the number of new/lost links over the past 6 months)
Strategy Application:
A B2B company noticed 70% of a competitor’s backlinks came from industry forums. It then strategically posted on 5 high-authority forums, increasing the backlink count from 80 to 350 within 4 months.
Paid Version Rank Tracking
Geolocation is precise down to the city level (error margin ±5 km), and device data is granular to specific models (e.g., iPhone 13 user click behavior differs from Android users). Immediate alerts are sent if a core keyword drops more than 3 positions, allowing webmasters to take remedial action within 24 hours, reducing the impact by 72%.
The paid version supports:
- Local Ranking and Local Pack Data (e.g., ranking changes for “New York dentist” in local search)
- Device Separation Statistics (mobile ranking is often 5-10 positions lower than PC)
- Competitor Comparison (simultaneously track your site’s and 3 competitors’ ranking fluctuations)
Paid Version On-Page Optimization Suggestions
The scoring system compares 128 features of the industry’s TOP 50 pages, providing pixel-precise suggestions (such as “move the keyword 15px to the left to increase visual weight”).
Each suggestion comes with an implementation difficulty score (1-5 stars) and expected effect prediction (e.g., “adding Product Schema can boost rich snippet display rate by 18%”).
Pages that fully adhere to the suggestions see an average CTR increase of 2.1 times, 53% higher than the industry benchmark.
The paid On-Page Grader offers 12 evaluation metrics:
- Title Tag Optimization (50-60 characters, includes primary keyword)
- Meta Description Integrity (120-160 characters, includes a call-to-action)
- H1 Tag Uniqueness (only 1 H1 per page, matching the title)

Local Pack rank tracking is precise to business hours (e.g., ranking is 2-3 positions higher during lunch hours), boosting walk-in conversion rate by 65%.
Features for physical stores:
