Quick answer
An SEO audit answers three questions: can Google crawl and index your site, is each page set up for the keyword it should rank for, and does the site have enough authority to compete? Work through technical checks, on-page checks and off-page checks, then sort every fix by impact and effort so you know what to do first.
Key takeaways
- Start in Google Search Console. It shows what Google actually sees, not what a tool guesses.
- Crawl the site with a tool like Screaming Frog to catch broken links, redirects and duplicates.
- Audit the pages that make money first. The blog can wait.
- The output should be a short, ranked to-do list, not a 200-page PDF.
Technical SEO audit checklist
Technical problems are the ones that quietly stop everything else from working. This is the list we run on every new site:
- Pages indexed vs submitted (Search Console, then Pages)
- robots.txt and noindex tags aren't blocking pages you need
- XML sitemap is clean and submitted
- Canonical tags point where they should (canonical guide)
- No redirect chains, no 404s on linked pages, no orphan pages
- HTTPS everywhere, and one preferred version of the domain
- Core Web Vitals pass on mobile
- Structured data is valid (Rich Results Test)
- hreflang is correct on multi-language sites (international SEO)
The most common issue we find isn't exotic. It's important service pages that Google simply hasn't indexed, often because of a leftover noindex tag from when the site was built.
On-page SEO checklist (with examples)
Once Google can see the page, check that it's actually set up to rank:
| Check | Good example |
|---|---|
| Title tag with main keyword | "Emergency Plumber in Tampa, 24/7 Callouts" |
| One H1 matching intent | "Emergency Plumber in Tampa" |
| Answer near the top | 2–3 sentence summary before details |
| Descriptive meta description | Benefit + proof + call to action |
| Internal links | Links to related services and guides |
| Image alt text | "Plumber repairing burst pipe in Tampa kitchen" |
Read each page as a customer would. If you can't tell within five seconds what the business does and where, neither can Google. More on titles and descriptions in our meta tags guide.
Off-page SEO checklist
Off-page SEO is your reputation outside your own site:
- Backlink profile: quality, relevance and any suspicious patterns (backlinks guide)
- Brand mentions that don't link to you yet
- Google Business Profile and directory listings that match exactly (local SEO)
- Reviews: how many, how recent, and whether you reply
For local businesses, the reviews line often matters more than links. A competitor with eighty recent reviews will usually beat a better website with twelve.
SEO audit template
Keep it simple. One row per issue:
| Issue | URL(s) | Impact (H/M/L) | Effort (H/M/L) | Owner | Status |
|---|---|---|---|---|---|
| Service pages missing from index | /services/* | High | Low | Dev | To do |
| Duplicate title tags | 14 URLs | Medium | Low | SEO | To do |
Then sort it: high impact and low effort at the top. That's your first 30 days. Everything else can wait until those are done.
Turning an audit into a proposal
An audit on its own doesn't change anything. A good SEO proposal turns it into a plan: the few issues that matter most, the opportunity in keywords and traffic, what happens in the first 90 days, which numbers you'll report on (SEO KPIs) and the terms.
If a proposal is mostly screenshots of tool scores, ask what they'll actually do in month one. Want us to run the audit for you? See technical SEO & audits.
