Everything you need for technical SEO
SpiderDog combines enterprise-grade crawling with industry-aware intelligence. From JavaScript rendering to client-ready reports, every feature is built to help you find, fix, and communicate technical SEO issues faster.
Crawling & Discovery
JavaScript Rendering
Our crawler executes JavaScript using Playwright, just like Googlebot. Catch client-side SEO issues that static crawlers miss — React, Vue, Angular, and dynamic content frameworks are fully supported.
Headless Browser Crawling
SpiderDog loads pages in a real Chromium browser, waits for hydration, and extracts the fully rendered DOM. This ensures you audit what search engines actually see, not just the raw HTML source.
Dual Viewport Crawling
Crawl every page with both mobile and desktop viewports to detect device-specific issues. Compare LCP, CLS, and INP between viewports and catch layout shifts or performance gaps that affect mobile rankings.
Respects robots.txt
Automatically fetches and obeys robots.txt directives before crawling. Avoid crawling disallowed paths and ensure your audits follow the same rules as search engine bots.
Technical SEO Auditing
On-Page SEO Validation
Audit page titles, meta descriptions, headings (H1-H6), canonical tags, Open Graph tags, and Twitter Cards. Detect duplicates, missing elements, length issues, and non-sequential heading structures.
Broken Link Detection
Find 404 errors, 500 server errors, and redirect chains across your entire site. Export broken links with their source pages so your team can fix them quickly.
Redirect Chain Analysis
Identify redirect hops, loops, and temporary redirects that should be permanent. Minimize redirect chains to preserve link equity and improve crawl efficiency.
Duplicate Content Detection
Discover exact duplicate pages, near-duplicates, and pages with thin content. Compare titles, meta descriptions, and body content to find duplication that dilutes your rankings.
Internal Link Analysis
Map your internal linking structure and identify orphaned pages. Find pages with too few or too many internal links and optimize your site architecture.
Indexability Checks
Detect noindex, nofollow, and canonical issues. Verify that your important pages are indexable and that low-value pages are properly excluded from search results.
Security Checks
Audit HTTP security headers, mixed content, and HTTPS coverage. Identify missing HSTS, CSP, X-Frame-Options, and X-Content-Type-Options headers that leave your site vulnerable.
Image SEO Checks
Find images missing alt text, oversized images slowing down your pages, and missing width or height attributes that cause layout shift. Keep your visual content search-friendly and fast.
Structured Data Extraction
Extract JSON-LD and microdata from every page during the audit. Identify missing or malformed structured data that could prevent rich snippets from appearing in search results.
Performance & Core Web Vitals
Core Web Vitals Monitoring
Measure Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) on every page. Track performance trends over time and prioritize fixes that impact rankings.
Lighthouse Integration
Run Google Lighthouse audits at scale across your entire site. Get performance, best practices, and SEO scores for every URL, not just a single page.
Page Speed Analysis
Identify slow-loading pages, large images, render-blocking resources, and excessive JavaScript. Get actionable recommendations to improve load times and user experience.
Industry-Aware Intelligence
Vertical-Specific Checks
E-commerce, healthcare, SaaS, local services, and more — each industry has unique SEO requirements. SpiderDog applies industry-specific rules to surface the issues that matter most for your vertical.
Competitor Benchmarks
See how your site stacks up against industry leaders. Get contextual benchmarks for content quality, indexability, and performance based on your specific vertical.
Structured Data Awareness
Industry-aware audits flag missing structured data patterns common in your vertical — from product schema for ecommerce to local business markup for service providers.
Reporting & Collaboration
Dual-Report Generation
Every audit produces two reports: a detailed technical report for developers and an executive summary for stakeholders. No more translating technical jargon into business language.
PDF Exports
Download professionally formatted PDF reports with health scores, issue summaries, and priority roadmaps. Share audit results with clients and team members in a ready-to-present format.
CSV & JSON Exports
Export raw crawl data in CSV or JSON format for further analysis in Excel, Google Sheets, or your own data pipelines. Every field is available for custom reporting.
Scheduled Monitoring
Set up daily, weekly, biweekly, or monthly automated audits. Track health score trends over time, catch regressions early, and prove the ROI of your SEO efforts with historical data.
Delta Reporting
Compare audits over time to see what changed. Identify new issues that appeared, issues that were fixed, and health score improvements between crawls.
GitHub Integration
Connect your GitHub repositories to correlate code deployments with SEO changes. Run audits on preview deployments and catch technical SEO regressions before they reach production.
Health Score Tracking
Monitor your site's overall SEO health score over time with trend charts. Visualize improvements and spot regressions at a glance across all your scheduled audits.
Keyword & Competitor Intelligence
Keyword Research
Discover search volume, keyword difficulty, CPC, search intent, and 12-month trends. Spot SERP-feature opportunities and filter keywords by your site authority.
Rank Tracking
Track keyword positions over time, see which URLs rank, and measure share of voice across your keyword portfolio. Hourly SERP refreshes keep data current.
Competitor Analysis
Compare your site to competitors, uncover keyword gaps, and rank competitors by strength. Identify the easiest opportunities to close.
Content Optimization
Turn any crawled URL into actionable content recommendations. Compare your page to top-ranking competitors and get specific fixes for titles, headings, length, and missing topics.
Backlink Intelligence
Backlink Analysis
Analyze referring domains, anchor text distribution, and link quality metrics via DataForSEO integration. Understand your backlink profile and identify toxic links that could trigger manual actions.
Backlink Add-On
Expand your backlink analysis with additional referring domain credits. Available as an add-on to any paid plan, billed on the same cycle as your subscription.
