How to Do an SEO Audit Step by Step (With a Free-Tools Checklist)

A business owner in Jalandhar says, "Our website used to get enquiries, now it doesn't." An SEO audit is how you find out why, calmly and systematically, instead of guessing. This SEO audit checklist walks through the exact order a professional follows, using only free tools, and ends with how to turn findings into a prioritised action plan.

Quick Answer

An SEO audit is a structured review of a website's search health. Step by step: define goals, crawl the site, check indexing in Google Search Console, test technical basics and Core Web Vitals, review on-page elements, audit content quality, check local listings and links, then prioritise fixes by impact and effort. Free tools cover nearly all of it.

What Is an SEO Audit?

An SEO audit is a diagnostic check of everything that affects a website's ability to be crawled, indexed, ranked and chosen by searchers and AI tools. Its output is not a score; it is a prioritised list of problems and opportunities with clear next steps.

An audit differs from a pre-publish checklist. The on-page SEO checklist helps you get a single new page right. An audit looks at the whole site, its history and its performance data to explain what is going wrong and where the biggest gains are.

Which Free Tools Do You Need for an SEO Audit?

• Google Search Console: queries, indexing, Core Web Vitals, links, manual actions.
• Google Analytics 4: landing page traffic, engagement and conversions.
• PageSpeed Insights: lab and field data for speed and Core Web Vitals.
• Screaming Frog SEO Spider (free version): crawls a limited number of URLs and lists titles, status codes, redirects, canonicals and missing tags.
• Google's Rich Results Test and Schema Markup Validator: check structured data.
• Chrome with "View page source" and DevTools: inspect tags and mobile layout.
• A plain Google search: "site:yourdomain.com" gives a rough idea of indexed pages, and brand searches show what customers see.

Paid suites like Semrush or Ahrefs add competitor and backlink depth, but they are not required for a solid first audit.

How Do You Do an SEO Audit Step by Step?

Step 1: Define goals and gather context

Ask the owner what the website must achieve: calls, WhatsApp enquiries, form fills, online orders. Ask what changed recently, such as a redesign, a new developer, a domain move or a switch from WordPress to Shopify. Many traffic drops trace back to one change on one date.

Step 2: Benchmark performance

In Search Console, compare the last three months with the same period a year earlier to remove seasonal effects. A sweet shop's traffic naturally rises before Diwali; a school admission site peaks in spring. Export top pages and queries so you can measure the effect of your fixes later.

Step 3: Crawl the website

Run Screaming Frog on the site and look for:

• 4xx errors (broken pages) and 5xx errors (server problems).
• Redirect chains, where one URL redirects to another that redirects again.
• Missing, duplicate or overly long title tags and meta descriptions.
• Missing or multiple H1 headings.
• Pages with a noindex tag or a canonical pointing elsewhere.
• Orphan pages that exist in the sitemap but receive no internal links.

Step 4: Check indexing

Open the Page Indexing report in Search Console. List important pages that appear under "Not indexed" and record the reason. Use URL Inspection on your home page and top service or product pages to confirm Google's chosen canonical matches yours. Our Google Search Console guide explains each status.

Step 5: Review technical foundations

• HTTPS on every page, with HTTP and non-preferred versions redirecting to one version.
• robots.txt not blocking important folders, and the sitemap listing only live, indexable URLs.
• Core Web Vitals (LCP, INP, CLS) in Search Console and PageSpeed Insights, checked on mobile first.
• Mobile layout: readable text, tappable buttons, no horizontal scrolling, no intrusive pop-ups.
• Structured data validating without errors.

Step 6: Audit on-page elements on key pages

Pick the ten pages that matter most commercially. For each, check whether the title and H1 reflect the main query, whether the first paragraph answers the searcher's question, whether headings are logical, and whether images have descriptive alt text and sensible file sizes.

Step 7: Audit content quality

A content audit is a page-by-page decision about what to keep, improve, merge or remove. Export all indexable URLs with their clicks and impressions, then label each one:

1. Keep: performing well and still accurate.
2. Improve: relevant but outdated, thin or missing clear answers.
3. Merge: two or more pages targeting the same intent; combine and redirect.
4. Remove or noindex: no value, no traffic, no links, such as expired offers.

Also check for trust signals: author names with real credentials, an about page, contact details and updated dates. These support E-E-A-T and make content more likely to be cited by AI search tools.

Step 8: Check internal links

Important pages should receive links from related pages with descriptive anchor text, not "click here". Our guide to internal linking and topic clusters shows how to structure this.

Step 9: Check local and off-page signals

• Google Business Profile: correct category, hours, photos, review replies.
• NAP consistency across directories like Justdial and IndiaMART.
• The Links report in Search Console: which sites link to you, and whether any look spammy or irrelevant.
• Brand search: what appears when someone searches your business name, including reviews.

Step 10: Check AI search visibility

Ask ChatGPT, Gemini and Perplexity the questions your customers ask, such as "Which export packaging suppliers are in Jalandhar?", and note whether your business is mentioned and what sources are cited. Check if Google shows an AI Overview for your main queries and which pages it links. This is a snapshot, not a precise metric, but it shows whether your content is being understood.

How Do You Prioritise Audit Findings?

An audit that lists a hundred problems without priorities is rarely acted on. Score each issue on two questions: how much will fixing it help, and how much effort does it take?

1. Fix first: high impact, low effort, such as an accidental noindex on a service page, a robots.txt block or missing redirects after a redesign.
2. Plan next: high impact, high effort, such as rewriting weak service pages or improving Core Web Vitals.
3. Batch later: low impact, low effort, such as tidying meta descriptions on old posts.
4. Ignore for now: low impact, high effort.

What Should an SEO Audit Report Include?

• A one-page summary in plain language for the owner: the top three problems and top three opportunities.
• Evidence for each finding, such as a screenshot or exported list.
• A recommended fix, the owner of that task (developer, writer, owner) and priority.
• Baseline numbers to compare against in the next review.

Key Takeaways

• An SEO audit diagnoses crawling, indexing, technical, on-page, content, local and off-page health.
• Free tools, especially Search Console, PageSpeed Insights and a crawler, cover most needs.
• Start with goals and recent changes; many drops come from a single event.
• A content audit decides what to keep, improve, merge or remove.
• Prioritise by impact and effort, and report in plain language with clear owners.

Frequently Asked Questions

How often should you do an SEO audit?

A full audit once or twice a year suits most small business websites, with a quick monthly check in Search Console in between. Always run an audit after a redesign, platform migration, domain change or sudden traffic drop, because these events commonly introduce indexing and redirect problems.

Can I do an SEO audit with only free tools?

Yes. Google Search Console, GA4, PageSpeed Insights, the free Screaming Frog crawler and Google's structured data testers cover crawling, indexing, speed, on-page and schema checks. Paid tools mainly add competitor analysis and deeper backlink data, which help but are not essential for a first audit.

How long does an SEO audit take?

For a small business site with a few dozen pages, a careful audit can take one to a few working days. Large e-commerce stores with thousands of product and filter URLs take much longer. Time depends more on site complexity and history than on the tools used.

What is the most common problem found in SEO audits?

In small business sites, frequent issues include pages accidentally set to noindex, broken redirects after a redesign, duplicate or thin pages competing for the same query, missing titles, slow mobile loading from heavy images, and inconsistent business details across directories and Google Business Profile.

What is the difference between an SEO audit and a content audit?

An SEO audit reviews the whole site, including technical health, indexing, links and local signals. A content audit is one part of it, focused on deciding which pages to keep, improve, merge or remove based on quality, accuracy and performance data.
