How to use Screaming Frog to audit a large e-commerce site: A Step-by-Step Guide to Boost Your Site’s SEO

Your time is valuable—make it count. If you’re running a large e-commerce site and wondering how to wrangle the chaos of hundreds or thousands of product pages, category pages, redirects, broken links and metadata nightmares, then you’re in the right place. At BlogCog, we get it: businesses want results, and you want your site to climb the Google rankings without pulling all-nighters. That’s where Screaming Frog comes in.

In this post we’ll walk you through exactly how to use Screaming Frog to audit a large e-commerce site (yes, that’s the question we’re tackling), in a fun, approachable way that speaks business owner to business owner. Think less technical jargon, more “okay let’s fix this and move traffic up”. Ready?

1. Why audit a large e-commerce site with Screaming Frog?

Large e-commerce sites pose unique SEO challenges. You’ve got thousands of product pages, category pages, filters, pagination – often built dynamically with query strings, layered navigation and more. Without a systematic audit you risk duplicate content, orphan pages, slow load times and internal linking problems. The nice bit? Screaming Frog helps you surface those hidden gremlins quickly. The tool is a desktop crawler that mimics how search engines explore your site. :contentReference[oaicite:0]{index=0}

And why do this? Because once you clean up architecture and metadata, you’ll be giving Google and Bing a much clearer signal about what your site is, what’s important, what to index—and what to ignore. At BlogCog, we believe in turning technical audits into actionable wins that boost traffic and move the needle.

2. Get set up: pre-crawl checklist

Before hitting “Start Crawl”, here’s your preparation list:

  • Ensure you’ve got the latest version of Screaming Frog. The paid version lifts the URL-limit cap (free version limited to ~500 URLs) which for large sites is simply not enough. :contentReference[oaicite:1]{index=1}
  • Decide on your scope. Are you crawling the entire site? Or a subset—say only product and category pages? Excluding unimportant areas (login pages, staging, admin) helps you stay focused. :contentReference[oaicite:2]{index=2}
  • Configure storage mode. For huge sites, switch from RAM to database storage mode via Configuration ? System ? Storage Mode. This prevents your machine from crashing or slowing to a crawl. :contentReference[oaicite:3]{index=3}
  • Exclude unnecessary file types: images, JavaScript, CSS, etc., if you only want to capture the HTML pages. Saves memory and speeds things up. :contentReference[oaicite:4]{index=4}
  • Connect APIs (optional but helpful): link your Google Analytics, Search Console, PageSpeed or other tools to bring in organic traffic, load time and other data into your crawl. This makes your audit richer. :contentReference[oaicite:5]{index=5}

    • 3. Launch the crawl and monitor progress

    Now you hit Start. For a large e-commerce site, you’ll see the number of URLs balloon quickly—tens of thousands isn't unusual. The Overview tab shows how many URLs are processed, how many blocked, etc. :contentReference[oaicite:6]{index=6}

    A few tips while it’s running:

    • Keep an eye on memory usage—if it spikes too high, pause, save your work and resume after adjustments.
    • Use the live filters to peek at errors, duplicate titles, missing metadata etc as they appear—so you’re not waiting until the end.
    • If the crawl is taking too long, consider limiting depth or excluding certain query parameters via Configuration ? Exclude/Include. For example: /blog/.* or ?color= to focus on core pages. :contentReference[oaicite:7]{index=7}

      • 4. Post-crawl: interpret key tabs and results

      Once the crawl finishes (or you stop it), time to dig into the gold. Here are the major tabs you’ll use—especially for large e-commerce audits:

      Response Codes

      This tab shows the HTTP status codes of all crawled URLs. Look out for: 404 (Not Found), 410 (Gone), 5xx server errors, redirect chains (301/302 loops). Fixing these helps both user experience and SEO. :contentReference[oaicite:8]{index=8}

      Page Titles & Meta Descriptions

      Here you’ll find missing titles/descriptions, duplicates, too long/short tags. For product and category pages, unique, descriptive metadata is essential. Screaming Frog flags these for you. :contentReference[oaicite:9]{index=9}

      Duplicate Content / URL Tab

      Large e-commerce sites often suffer from duplicate content via filters, pagination, session parameters or multiple URL versions. Screaming Frog identifies duplicates (via MD5 hash) and dynamic URLs. You’ll want to canonicalize, redirect or exclude accordingly. :contentReference[oaicite:10]{index=10}

      Internal & Inlinks/Outlinks

      Check the internal linking structure: pages with no inlinks (orphan pages) may not be discovered by search engines easily. Ensure important product/category pages receive internal links from blog posts, navigation or other areas. The Inlinks/Outlinks tabs help identify weak spots. :contentReference[oaicite:11]{index=11}

      Images

      Images are often overlooked in e-commerce. Screaming Frog’s Images tab shows missing alt text, large file sizes, duplicates, etc. These affect page speed and accessibility. :contentReference[oaicite:12]{index=12}

      5. Actions: Prioritise and execute fixes

      So you have the data—what do you do next? Here’s our priority list (with a little BlogCog flair):

      1. Fix critical errors – 404s, 5xx errors, redirect loops. These are the gremlins of your crawl and should be squashed first.
      2. Optimize metadata – Unique and appealing titles/meta descriptions on category and product pages help click-through and rankings.
      3. Tame duplicates and URLs – Decide on canonicalization, parameter exclusion, or redirects. For large sites, ignoring this could stall your SEO.
      4. Strengthen internal linking – Ensure key pages get meaningful internal links. As a business owner, think of it like guiding Google exactly where you want it to go.
      5. Speed and images – Use the Images tab data to compress large images, add missing alt tags, and reduce load times. Slow sites lose rankings and customers.
      6. Schedule regular audits – Large e-commerce sites are living beasts: new products, new filters, old pages. Make crawling part of your regular SEO rhythm. :contentReference[oaicite:13]{index=13}

        7. 6. Use BlogCog to scale your content for audit wins

        7. Common mistakes to avoid

        Let’s have a quick laugh (and a moment of learning):

        • Skipping the crawl because “we’ve done SEO before” – Large sites change fast; don’t assume everything is fine.
        • Focusing only on content but ignoring technical foundation – It’s like building a mansion on sand. The crawl is your foundation.
        • Ignoring internal links and calling it done – You may have thousands of product pages but if they’re isolated, they won’t rank.
        • Leaving crawl as a one-time fire drill – Instead schedule regular audits so you catch issues early.

        8. Final thoughts
