Moz Pro Tutorial: Site Crawl, Link Analysis, and Domain Authority Tracking in 2025

Moz Pro offers a suite of SEO tools centered around site crawling, keyword research, and link analysis. Its flagship metrics, Domain Authority (DA) and Spam Score, have long been industry benchmarks. In 2025, Moz Pro updated its crawl engine with improved JavaScript rendering and expanded its Link Explorer index to over 40 trillion links. This guide walks developers through the technical workflows that matter most: configuring a site crawl, analyzing backlinks with Moz's proprietary metrics, and building automated reporting.

Moz Pro's Site Crawl tool audits your site for over 100 technical issues. To configure a crawl, create a new campaign and enter your root domain. Under "Crawl Settings," you can customize:

• Crawl scope: Limit the crawl to specific subdirectories if you only need to audit a section of the site. For example, /blog/* for a content audit.
• Crawl speed: Adjust requests per second. Moz recommends starting with 2 requests per second for shared hosting environments to avoid tripping rate limits (Moz, 2025, "Moz Pro Site Crawl: How to Diagnose Technical SEO Issues").
• Exclude patterns: Add URL patterns to skip, such as /tag/, /author/, and pagination paths like page/*.

The crawl report categorizes issues by severity: Critical, Warning, and Notice. Critical issues include broken links, missing title tags, and duplicate meta descriptions. Each issue displays the affected URL count and a direct link to the page source, making debugging faster.

For JavaScript-heavy sites, enable the "Render JavaScript" option. Moz Pro uses a headless browser to execute JavaScript and discover links that are injected dynamically. This is essential for single-page applications and sites built with modern frameworks (Moz, 2025, "JavaScript SEO: Best Practices for Crawling and Indexing").

Moz's Link Explorer indexes over 40 trillion links and provides two key metrics. Domain Authority (DA) is a predictive score from 1 to 100 estimating how well a domain is likely to rank, computed using machine learning against a neural network trained on Mozscape data. Spam Score is a percentage that indicates how many features of a link profile correlate with penalized sites. A Spam Score above 30 percent warrants manual review.

To run a link analysis, enter your domain in Link Explorer and review the "Top Pages" report. This shows which pages on your site have earned the most linking domains. Export the "Linking Domains" list as CSV and cross-reference it with your Google Search Console data to validate which links are being recognized by search engines (Moz, 2025, "Link Explorer: How to Research and Analyze Backlinks").

Moz's Keyword Explorer provides search volume, organic click-through rate, and Priority Score. The Priority Score is a calculated metric that combines volume, difficulty, and organic CTR into a single numeric value, helping teams prioritize which keywords to target.

For technical SEO teams, the "SERP Features" filter is critical. It shows whether a keyword returns featured snippets, knowledge panels, or People Also Ask boxes. Knowing which SERP features are present helps you decide whether to target the keyword or optimize for a position above the fold (Moz, 2025, "Keyword Explorer: The Complete Guide to Keyword Research").

Moz offers a REST API (Mozscape API) that provides programmatic access to link metrics, including DA, Page Authority, and Spam Score. The API uses a signed authentication method with an access ID and secret key. Rate limits depend on your subscription tier, ranging from 1 request per second to 10 requests per second.

Developers can integrate Moz metrics into custom dashboards or use them to enrich data from other SEO tools. For example, combining Moz DA scores with SEMrush or Ahrefs backlink data provides a more complete picture of link equity.

Moz Pro delivers reliable site crawling, authoritative link metrics, and actionable keyword insights. Run the Site Crawl tool weekly, review Link Explorer for new and lost linking domains, and track DA trends monthly. The Mozscape API allows you to build custom reporting pipelines that keep your team informed without manual exports. A regular cadence with Moz Pro ensures your technical SEO efforts are grounded in solid data.
