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.
