You have probably seen the term "SEO audit" everywhere — but what does it actually mean? And more importantly, what will it tell you about your website? This guide explains every factor a proper SEO audit checks, why each one matters, and what to do about the results.
At the end, you can run a free audit on your own website and get a detailed report in seconds.
What Is an SEO Audit?
An SEO audit is a comprehensive health check for your website. It analyses your site against the factors that Google and other search engines use to decide rankings. Think of it like a medical checkup — it finds problems before they become serious and tells you what is healthy and what needs attention.
A good audit checks three categories:
- On-page SEO — Content, headings, meta tags, keywords, images
- Technical SEO — Speed, mobile-friendliness, security, crawlability
- Off-page signals — Structured data, social presence, backlink quality
What a Free SEO Audit Checks (30+ Factors Explained)
Meta Tags and Title Optimisation
Title Tag
The title tag is the blue clickable heading in Google search results. It is the most important on-page SEO factor. An audit checks:
- Does every page have a unique title tag?
- Is it between 50–60 characters? (Google truncates longer titles)
- Does it include relevant keywords?
- Is it descriptive and click-worthy?
Why it matters: Pages without title tags or with generic titles ("Home", "Untitled") almost never rank well.
Meta Description
The short text below the title in search results. An audit checks:
- Does every page have a meta description?
- Is it between 120–155 characters?
- Does it include a call to action?
Why it matters: While meta descriptions are not a direct ranking factor, they affect click-through rate (CTR) — which is.
Canonical Tags
Canonical tags tell Google which version of a page is the "main" one — important if you have duplicate or similar content.
- Does every page have a canonical tag?
- Is it pointing to the correct URL?
Heading Hierarchy
Proper heading structure (H1, H2, H3) helps Google understand your content and improves accessibility.
- Does every page have exactly one H1 tag?
- Are headings used in logical order (H1 → H2 → H3)?
- Do headings include relevant keywords naturally?
- Are there any skipped levels (H1 → H3 with no H2)?
Image Optimisation
Images are often the largest files on a webpage. An audit checks:
- Do all images have alt text? (Required for accessibility and SEO)
- Are images compressed? (Large images slow down your page)
- Are modern formats used? (WebP is 30–50% smaller than JPEG/PNG)
- Are image dimensions specified? (Prevents layout shifts)
Common finding: 80% of websites we audit have missing alt text on at least half their images.
Core Web Vitals
Core Web Vitals are Google's official metrics for user experience. They are a confirmed ranking factor since 2021.
LCP — Largest Contentful Paint
How long it takes for the main content to appear on screen. Good: under 2.5 seconds. Poor: over 4 seconds.
FID / INP — First Input Delay / Interaction to Next Paint
How quickly your site responds when someone clicks a button or link. Good: under 100 milliseconds. Poor: over 300 milliseconds.
CLS — Cumulative Layout Shift
How much the page layout moves around while loading. You know that annoying thing where you try to click a button and the page shifts, so you click something else? That is CLS. Good: under 0.1. Poor: over 0.25.
Mobile Responsiveness
Over 75% of Indian internet users access the web through mobile phones. Google uses mobile-first indexing — it primarily looks at the mobile version of your site.
- Does your site look good on mobile screens?
- Are buttons and links large enough to tap?
- Is text readable without zooming?
- Does the viewport meta tag exist?
Page Speed
Beyond Core Web Vitals, overall page speed affects both ranking and user experience.
- What is your total page load time?
- How large is your page (total file size)?
- How many HTTP requests does your page make?
- Is browser caching enabled?
- Is GZIP/Brotli compression active?
Benchmark: For Indian users on average mobile connections, your page should load in under 3 seconds.
Structured Data (Schema Markup)
Structured data helps Google understand your content and can earn you rich snippets (star ratings, FAQ dropdowns, product prices in search results).
- Does your site have any structured data?
- Is it valid (no errors)?
- Are you using relevant types? (LocalBusiness, Product, FAQ, BreadcrumbList)
Why it matters: Pages with rich snippets get 20–30% more clicks than plain results. Structured data is also critical for appearing in AI search results (ChatGPT, Gemini, Perplexity).
Security (HTTPS / SSL)
- Does your site use HTTPS?
- Is the SSL certificate valid and not expired?
- Are there any mixed content warnings (HTTP resources on an HTTPS page)?
Why it matters: Google gives a ranking boost to HTTPS sites. Chrome marks HTTP sites as "Not Secure" — which destroys trust.
Broken Links
- Are there any internal links pointing to pages that do not exist (404 errors)?
- Are there broken external links?
Broken links waste "link equity" (the ranking power that flows between pages) and create a poor user experience.
Crawlability
- Does your site have a robots.txt file? Is it configured correctly?
- Does your site have an XML sitemap? Is it submitted to Google Search Console?
- Are important pages accidentally blocked from crawling?
- Is your site's URL structure clean and logical?
Content Quality Signals
- How many words are on your key pages? (Thin content under 300 words rarely ranks)
- Is content original? (Duplicate content from other sites is penalised)
- Are keywords present in the content naturally?
- Do pages have a clear topic focus?
Social and External Signals
- Does your site link to social media profiles?
- Is there an Open Graph image and description for social sharing?
- Does the site have a Google Business Profile linked?
How to Read Your Audit Report (Priority Order)
Not all audit findings are equally important. Here is the priority order for fixing issues:
| Priority | Category | Fix Impact |
|---|---|---|
| 🔴 Critical | No HTTPS, site not indexed, broken homepage | Immediate — site is basically invisible |
| 🟠 High | Missing title tags, slow page speed, not mobile-friendly | Significant ranking improvement |
| 🟡 Medium | Missing meta descriptions, broken links, missing alt text | Moderate improvement |
| 🟢 Low | Missing structured data, social tags, minor CLS issues | Nice to have, improves over time |
Rule of thumb: Fix critical and high-priority issues first. These give you 80% of the improvement for 20% of the effort.
Free Audit vs Paid Audit: What Is the Difference?
| Feature | Free Audit | Paid / Professional Audit |
|---|---|---|
| Pages scanned | 1–10 pages | Entire site (100–10,000+ pages) |
| Technical depth | Surface-level checks | Deep crawl, JavaScript rendering, log analysis |
| Competitor analysis | Not included | Compares you against top competitors |
| Actionable recommendations | General tips | Specific, prioritised action plan |
| Backlink analysis | Not included | Full backlink profile review |
| Content gap analysis | Not included | Identifies missing topics and keywords |
| Cost | ₹0 | ₹5,000 – ₹25,000 (one-time) |
A free audit is an excellent starting point. It catches the most common issues and gives you quick wins. A paid audit is worth it when you have fixed the basics and want to compete for high-value keywords.

Frequently Asked Questions
How often should I run an SEO audit?
Run a basic audit every 1–3 months. Run a comprehensive audit (paid) once or twice a year. Also run an audit after any major website changes — redesign, new pages, platform migration, or hosting change.
Will an SEO audit improve my ranking?
The audit itself does not improve anything — it identifies the problems. The improvement comes when you fix the issues it finds. Think of it as a diagnosis, not a treatment. But knowing what to fix is half the battle.
How much does a professional SEO audit cost in India?
Free tools (like ours) give you a solid baseline at ₹0. Professional audits from agencies range from ₹5,000 to ₹25,000 depending on site size and depth. Enterprise audits for large sites (1,000+ pages) can cost ₹50,000+.
What is a good SEO audit score?
Most audit tools use a 0–100 scale. A score of 80+ is good. 60–80 means there are significant issues to fix. Below 60 means the site needs serious attention. Our experience: the average Indian small business website scores 35–55 on their first audit.
Can I fix SEO issues myself or do I need a developer?
Many issues are fixable without coding — updating title tags, adding alt text to images, writing better meta descriptions, compressing images. Technical issues (page speed, structured data, server configuration) typically need a developer. Our audit report tells you which is which.
What is the difference between an SEO audit and a website audit?
They are often used interchangeably. An "SEO audit" focuses on search engine optimisation factors. A "website audit" may also include design, usability, conversion rate, and security. Our free tool covers the SEO essentials that have the biggest impact on your Google ranking.
