The Problem

Challenges Faced

Drifters Gear's catalog spans more than 100,000 pages — far beyond what a standard audit tooling budget can cover in one pass — and the site's backlink profile, broken-page footprint, and account access had never been systematically reviewed.

A Catalog Far Beyond Standard Crawl Budgets

With more than 100,000 pages against a 5,000-credit Ahrefs allowance, a full single-pass crawl of the site wasn't realistic — the audit needed to be scoped and sequenced deliberately to get a representative technical picture.

Access & Verification Barriers Before Work Could Start

Without admin or email access, and with a Semrush account stuck in verification, the backlink audit couldn't even begin — the diagnostic work had to wait on account-level issues being resolved first.

An Unquantified Backlink & Toxic Link Risk

The site's referring domains had never been systematically reviewed, leaving it unclear how many backlinks were genuinely toxic versus simply unusual — a distinction that matters before disavowing anything.

Broken Pages Scattered Across a Massive Catalog

404 pages needed to be identified and individually confirmed as genuinely broken before any cleanup or redirect strategy could be planned — at this scale, a false positive could send the wrong pages into a fix queue.

The Approach

Our Strategy

A methodical, scoped diagnostic process — get access sorted, run a right-sized audit, and verify every finding manually before it goes into a fix plan.

01
Access & Verification Resolution
  •  
    Worked through initial account access and Semrush verification barriers that were blocking the audit from starting at all
  •  
    Secured working Ahrefs and Semrush access to get the technical crawl and backlink audit underway
02
Scoped Technical Audit at Scale
  •  
    Sequenced a 20,000-page Semrush crawl and worked within Ahrefs' credit limits to get a representative technical picture of a 100,000+ page catalog
  •  
    Delivered full Semrush and Ahrefs Site Audit reports as the baseline for prioritizing fixes in the next phase of work
03
Backlink & Toxic Link Analysis
  •  
    Extracted and reviewed 1,000+ backlinks from Ahrefs — the maximum available without a paid plan — alongside a full referring-domains export
  •  
    Ran toxic link reports through both Semrush and Ahrefs, then manually double-checked flagged URLs to separate genuinely toxic links from false positives
04
404 & Broken Page Diagnostic
  •  
    Compiled a full report of every 404 page identified across the site
  •  
    Manually verified that every URL flagged as broken was, in fact, broken — confirming the diagnostic before any cleanup work begins

About The Client

Drifters Gear

Drifters Gear is an online retailer of outdoor, hunting, and shooting gear, operating one of the larger product catalogs in its space at more than 100,000 pages. A site of that scale needed a technical SEO partner who could scope an audit properly rather than treat it like a small storefront — sequencing crawls within real tool limits and verifying findings manually before recommending any fix.
