How Domain Authority Applies to Shopify Stores
Domain Authority (DA) is a third-party metric developed by Moz that predicts how well a domain ranks in search engines on a 1–100 logarithmic scale. For Shopify stores, DA carries the same meaning it does for any domain — a higher score correlates with stronger backlink profiles and broader organic visibility. The critical distinction is that Shopify's platform architecture introduces structural constraints that affect how you build and maintain DA compared to stores on self-hosted platforms like WooCommerce.
Shopify stores operate on a subdomain of myshopify.com during development, but live stores function on a custom domain (e.g., yourbrand.com). All DA-building efforts must target that custom domain exclusively. Any backlinks pointing to your myshopify.com URL do not transfer authority to your custom domain and are wasted from an SEO standpoint. Verifying your custom domain is set as the primary domain in Shopify Admin is a prerequisite before any link-building campaign.
Shopify's Built-In SEO Limitations That Affect DA Growth
Shopify generates several structural issues that slow DA accumulation. The platform automatically creates duplicate URLs for product pages — a product lives at both /products/product-name and /collections/collection-name/products/product-name. Shopify adds a canonical tag pointing to the /products/ version, which prevents a duplicate content penalty, but if external sites link to the /collections/ URL variant, that link equity routes to a page Shopify considers non-canonical. Outreach assets and link targets should always use the canonical /products/ URL.
Shopify does not allow editing of the robots.txt file on standard plans — it is auto-generated. This means you cannot block crawling of thin paginated pages or faceted navigation URLs that dilute crawl budget. Shopify Plus merchants gained robots.txt editing access in 2021, which gives them a material crawl-efficiency advantage. For non-Plus stores, the workaround is to use noindex meta tags (available through theme liquid edits or apps) on low-value pages, preserving crawl budget for pages that actually build topical authority.
Shopify also enforces a fixed URL structure. Blog posts live at /blogs/blog-name/article-name and collections at /collections/collection-name. You cannot move content to a flat URL like /article-name or create custom subdirectories. This limits how you architect content silos — a structural technique that concentrates topical authority. Accepting this constraint means compensating with strong internal linking within the allowed structure.
Apps and Tools for Tracking DA on Shopify
DA is not a native Shopify metric — Shopify's built-in analytics do not report it. Tracking DA requires third-party tools. Moz Pro and Moz's free Link Explorer are the authoritative sources for Moz DA specifically. Ahrefs Domain Rating (DR) and Semrush Authority Score are competing metrics that measure similar backlink strength signals, and all three are commonly used together to triangulate a store's link profile health.
Within the Shopify App Store, apps like Plug in SEO and SEO Manager surface on-page recommendations but do not report DA — they do not have access to Moz, Ahrefs, or Semrush data. For DA tracking on Shopify, the workflow is to connect your custom domain directly to Moz Pro, Ahrefs, or Semrush and monitor DA alongside your organic traffic in Google Search Console. Search Console integration is available natively in Shopify Admin under Analytics > Reports for stores using Shopify's built-in integration, and it remains the most reliable source of actual keyword performance data.
Link-Building Tactics Specific to Shopify Stores
Shopify's blog functionality (under /blogs/) is the primary content vehicle for earning editorial backlinks. Unlike a WordPress installation, Shopify's blog editor is limited — no native categories beyond the blog-name grouping, no related posts functionality without apps, and limited schema support. Despite this, publishing detailed buying guides, product comparison posts, and industry data on the Shopify blog produces linkable assets that other sites reference. The content quality determines link acquisition; the platform's blog limitations are cosmetic, not fatal.
Product review and press coverage links are a high-DA link source accessible to Shopify stores. Journalists and bloggers who cover products routinely link to the product page or homepage on the merchant's custom domain. Ensuring those pages load fast and present clearly — Shopify's CDN handles asset delivery reliably — means the destination pages that receive links are technically sound. For collection pages targeting competitive category keywords, acquiring even a few links from industry publications measurably increases DA and ranking position simultaneously.
Supplier and manufacturer backlinks are a systematic source many Shopify merchants overlook. Brands that carry authorized products from recognizable manufacturers qualify to request a listing on the manufacturer's retailer or stockist page. These links come from high-DA root domains, require no content creation, and are repeatable across every brand in a store's catalog.
Working Around Shopify's URL Structure to Protect Link Equity
When Shopify merchants change themes, reorganize collections, or delete products, URLs change and existing backlinks break. A backlink pointing to a deleted product or renamed collection returns a 404 error, and the link equity is lost. Shopify does not create automatic redirects when URLs change — redirects must be manually added in Admin under Navigation > URL Redirects, or in bulk via CSV upload. Auditing redirect coverage after any site restructure is essential for preserving accumulated DA.
301 redirects in Shopify pass link equity to the destination URL. The practical rule: any URL that has earned backlinks — verified through Ahrefs or Moz — must have a 301 redirect in place before the original URL is retired. For large catalogs, tools like Ahrefs' Site Audit or Screaming Frog can export all URLs with backlinks, and that list becomes the mandatory redirect checklist after any migration or restructure.
Actionable Priority Order for Shopify DA Growth
Start by confirming the custom domain is set as the primary domain in Shopify Admin and that all myshopify.com URLs redirect to it. Then audit existing backlinks via Moz or Ahrefs to identify any links pointing to non-canonical /collections/ product URLs or dead pages, and add 301 redirects for every broken link destination. These two steps stop DA from leaking before any new link-building begins.
Next, publish at minimum four substantive blog posts on /blogs/ targeting topics where your store has legitimate depth — product category guides, comparison content, or original data. Use these as outreach assets to earn links from relevant industry sites, suppliers, and press. Finally, set a monthly reminder to check DA in Moz alongside your referring domain count in Ahrefs. DA growth on a new Shopify store is slow — expect meaningful movement over six to twelve months of consistent link acquisition, not weeks.
