Why Ecommerce Stores Need a Domain Authority Audit
Domain Authority (DA) is a third-party score. Developed by Moz. That predicts how well a domain ranks in search engines on a 1-to-100 logarithmic scale. For ecommerce stores, a weak DA means category pages, product pages, and blog content compete poorly against established retailers for the same keywords. Auditing DA is not a one-time task. It surfaces the specific signals. Backlinks, technical health, internal linking. That drag the score down and suppress organic revenue.
This checklist covers 12 discrete audit items, each with a defined pass condition and a fail condition. Work through them in order. Items 1-4 address backlink quality, items 5-8 address technical and on-page signals, and items 9-12 address internal authority distribution. Completing all 12 gives a complete picture of where DA is being built and where it is being lost.
Backlink Profile Checks (Items 1–4)
Item 1. Root Domain Backlink Count. Pull your linking root domains in Moz, Ahrefs, or Semrush. Pass: the count has grown or held steady over the trailing 90 days. Fail: the count has dropped by more than 5% in 90 days, signaling lost links that need reclamation outreach.
Item 2. Spam Score of Linking Domains. In Moz, filter your backlink profile by Spam Score. Pass: fewer than 10% of linking domains carry a Spam Score above 30. Fail: 10% or more sit above 30, requiring a disavow file review in Google Search Console.
Item 3. Anchor Text Diversity. Export your top 200 backlinks and tally anchor text. Pass: branded and naked-URL anchors together account for more than 50% of anchors. Fail: a single keyword phrase appears in more than 20% of anchors, which signals over-optimization risk.
Item 4. Competitor DA Gap. Record the DA of your top three organic competitors for your highest-volume category keyword. Pass: your DA is within 10 points of the median competitor DA. Fail: the gap exceeds 10 points, meaning link acquisition must accelerate before rankings can close.
Technical and On-Page Authority Checks (Items 5–8)
Item 5. Crawlability of High-Value Pages. Run a crawl in Screaming Frog or a comparable tool. Pass: all category and top-revenue product pages return a 200 status and appear in your XML sitemap. Fail: any high-value page returns a 4xx or 5xx code, or is excluded from the sitemap, blocking link equity flow.
Item 6. HTTPS Implementation. Check that every page. Including checkout and account pages. Serves over HTTPS and that HTTP URLs 301-redirect to HTTPS equivalents. Pass: zero mixed-content warnings and all HTTP variants redirect cleanly. Fail: any page has mixed content or a broken redirect chain, which dilutes the trust signals Google associates with the domain.
Item 7. Core Web Vitals. Pull your CWV data from Google Search Console under Experience > Core Web Vitals. Pass: more than 75% of URLs are rated Good. Fail: more than 25% are rated Needs Improvement or Poor. Page experience is a confirmed ranking signal that affects how Google evaluates the overall domain.
Item 8. Duplicate Content Across Category Filters. Use your crawl tool to identify near-duplicate URLs generated by faceted navigation (color, size, price filters). Pass: filter URLs are either canonicalized to the base category URL or blocked via robots.txt. Fail: duplicate filter URLs are indexed and receiving backlinks, which splits link equity across dozens of thin pages.
Internal Authority Distribution Checks (Items 9–12)
Item 9. Orphaned Pages. Identify pages with zero internal links pointing to them. Pass: no indexed page has zero internal inbound links. Fail: any page that ranks or targets keywords exists as an orphan, receiving no crawl priority or PageRank from the rest of the site.
Item 10. Internal Link Depth to Category Pages. Measure the click depth from the homepage to each top-level category. Pass: all primary category pages are reachable within three clicks from the homepage. Fail: any category page requires four or more clicks, which reduces its effective authority relative to competitors who structure their sites more shallowly.
Item 11. Homepage Link Equity Distribution. Audit the homepage's internal links. Pass: every top-revenue category receives at least one direct internal link from the homepage. Fail: a top-revenue category has no homepage link and relies solely on the navigation menu, reducing its perceived importance to crawlers.
Item 12: 301 Redirect Chain Length. Export all redirect chains using your crawl tool. Pass: all redirects resolve in a single hop (A → B, not A → B → C). Fail: any redirect chain exceeds two hops, as each hop dissipates a measurable portion of the link equity that backlinks pass to the destination URL.
Scoring Your Audit and Prioritizing Fixes
Score each item as Pass (1 point) or Fail (0 points). A score of 10-12 indicates a healthy DA foundation that supports organic growth. A score of 7-9 indicates moderate risk. Prioritize the failed backlink checks first since they have the most direct effect on DA. A score below 7 indicates systemic issues that suppress rankings across the entire domain.
Fix items in this sequence: technical failures (items 5-8) first because they block equity from flowing anywhere on the site, then backlink cleanup (items 1-3) to remove negative signals, then internal link structure (items 9-12) to distribute the equity you already have more efficiently. Backlink acquisition (item 4) is the only lever that requires ongoing external effort and produces results on a longer timeline than the other fixes.
