Website Crawl Analysis Tools: An Ecommerce Guide

Use a site crawler to map internal links, Google Search Console to investigate Google's indexing, and performance tools to diagnose delivery problems. Each answers a different question. For an ecommerce store, the most useful audit connects those findings to the products and collections shoppers need to reach.

Key takeaways

• Screaming Frog and Lumar map site structure. Search Console reports Google's view of your site.
• Crawl depth is a prioritization signal, not a universal ranking rule. Investigate important pages that are difficult to reach.
• Faster server responses can support crawling, but do not guarantee more crawling or indexing.
• Nostra addresses delivery and bot traffic. It complements a structural audit rather than replacing one.

Which tools should you use?

This is a comparison by use case, not a hands-on ranking of every product. Start with the question you need answered before choosing a platform.

• Screaming Frog SEO Spider
  Best fit: A detailed site-structure audit
  What to inspect: Internal links, crawl depth, response codes, redirects and duplicate URLs
• Lumar, formerly Deepcrawl
  Best fit: Cloud-based technical health monitoring
  What to inspect: Scheduled crawls, site changes and recurring technical issues
• Google Search Console
  Best fit: Understanding Google's discovery and indexing
  What to inspect: Page Indexing, URL Inspection and Crawl Stats
• PageSpeed Insights
  Best fit: Investigating an individual page's performance
  What to inspect: Real-user data where available and lab diagnostics
• Nostra
  Best fit: Improving delivery and managing bot traffic
  What to inspect: Storefront speed and traffic filtering alongside structural fixes

Screaming Frog's internal linking guide explains how to inspect crawl depth. Lumar's documentation describes its cloud crawler and scheduled monitoring. Deepcrawl is Lumar's former name.

What does a crawl-path audit reveal?

A crawl shows the links the tool can follow from its starting URL. Use it to find broken navigation, avoidable redirects, important pages with few internal links, and filter combinations that create large numbers of duplicate URLs.

Depth depends on the starting page and crawler settings. A product four clicks from the homepage is worth reviewing, but the number alone does not prove a ranking problem. Ask whether that product is commercially important, whether shoppers can find it, and whether relevant collections link to it.

A crawl also has blind spots. Compare its URL list with your sitemap and product inventory to identify pages missing from the discovered structure. Record whether JavaScript rendering was enabled so that a later comparison uses the same conditions.

How should you investigate indexing problems?

Use Search Console to inspect representative URLs from each affected template. Check whether a missing product is discoverable, indexable and correctly canonicalized before blaming infrastructure. A crawler's successful fetch is not evidence that Google has indexed the page.

For a small store, start with navigation, useful product content, sitemap accuracy and the Page Indexing report. Google's crawl-budget guidance is primarily aimed at very large or rapidly changing sites. Crawl budget reflects both capacity and demand; faster responses do not compel Google to crawl or index additional pages.

Where do speed and bot protection fit?

Slow responses and server errors can constrain crawling. If logs show an infrastructure bottleneck, investigate origin response times, cache behavior and traffic spikes alongside your URL structure. Malicious bots do not directly spend Google's crawl allocation. They can compete for server resources, which may affect the site's ability to serve legitimate requests.

Nostra's Dash agent supports page acceleration through Edge Delivery, while Knox handles bot protection through Edge Protect. These roles are described in the Nostra product roadmap. Neither service replaces decisions about internal links, canonical URLs or which filtered pages should be indexable.

Review bot controls carefully: a security rule that blocks a wanted crawler can undermine discovery. Keep verification and access policies explicit, and check logs after changing them.

A practical ecommerce audit workflow

1. Select a sample. Include high-value products, collections, new launches and pages with declining organic traffic.
2. Save the baseline. Record crawler settings, discovered URLs, response codes and important internal links.
3. Compare with Search Console. Inspect examples of missing or excluded pages and identify the reason before assigning a fix.
4. Separate the work. Send linking and canonical problems to the SEO or content owner; route server errors and delivery issues to engineering.
5. Prioritize customer impact. A broken route to a bestselling collection can matter more than reducing depth on a low-value archive.
6. Verify after release. Repeat the same crawl, test the affected journeys and monitor indexing separately. Do not equate a higher crawl count with more revenue.

Frequently asked questions

Does Search Console replace a crawler?

No. It provides Google's indexing and search reports. A dedicated crawler gives you a configurable view of the links and URLs it can discover across your site.

Is every page more than three clicks deep a problem?

No. Evaluate depth in the context of site size and page importance. Prioritize useful links that help visitors reach relevant products.

Will a faster site get every product indexed?

No. Delivery is only one part of the investigation. Content, discovery, canonicalization and Google's indexing decisions still matter.

Where should Nostra fit in my tool stack?

Use it when delivery performance or unwanted automated traffic needs attention. Keep your crawler and Search Console workflow for structural diagnosis. Book a Nostra demo to review your store's delivery and bot-traffic needs.
