SEO audit skills
employers want

SEO auditing is reviewing a site's search performance and health and turning findings into a prioritised plan. Troubleshooting is diagnosing a specific problem — usually a traffic drop — from evidence. Both cover technical health, indexing, content quality, links, search features and measurement, and both end with action.

The causes of drops have multiplied. Some are on the site: migrations, template bugs, robots rules, canonicals — exactly what Search Console's page indexing report is built to reveal.³ Some are algorithmic: Google says its March 2024 core update and new spam policies reduced low-quality, unoriginal content in results by 45%.²⁵ And some aren't ranking losses at all: Ahrefs found that when AI Overviews appear, the top-ranking page receives about 34.5% fewer clicks, rising to 58% in a later update.¹ Google's own guide to debugging traffic drops groups the usual suspects in the same way — technical problems, security and spam issues, algorithm updates, changes in search interest and site moves.⁴

Table: How SEO auditing has changed (editorial summary)

• A real audit with an executive summary and top priorities
• One traffic-drop diagnosis with evidence
• A migration or redesign pre-launch checklist
• Before-and-after results of fixes you recommended
• A Search Console segmentation you can walk through
• A verified SEO auditing certification

Show diagnosis and impact: "Diagnosed 40% traffic loss to a canonical template bug within 48 hours; recovery within 3 weeks; introduced pre-release SEO checks that prevented two further regressions."

"Traffic dropped. What do you check first?"

Whether it's real (tracking, seasonality), then where it happened and whether impressions or just clicks fell.

"How do you prioritise audit findings?"

By business impact, confidence and effort; most sites need a few big fixes, not hundreds of small ones.

"How do you know if a Google update hit you?"

Timing that matches the update, broad drops in specific content types, and no technical cause — then review quality against the guidance.

"What goes in a migration audit?"

URL mapping and redirects, canonical and hreflang checks, crawl comparisons, staging tests and post-launch monitoring.

"How do you present an audit to executives?"

Problem, cause, impact in revenue terms, top three actions, owners and timeline.

Auditors build credibility by being right and being brief. In the first month, build a baseline: how each section performs, what the indexing report shows, and when past drops happened and why. Then deliver an audit of a few pages, not a hundred, focusing on the handful of issues that matter most, with evidence and owners. Follow up until fixes ship and verify the results. Finally, move from cure to prevention: agree checks for releases and migrations and set alerts for sudden changes. SEOs who prevent problems rather than just report them are the ones trusted to lead SEO functions.

• Crawler exports as audits.
• Fixing before diagnosing.
• Blaming every drop on Google.
• No business impact.
• No verification after fixes.
