Free SEO Audit Checklist: 15 Things to Check Before You Pay Anyone
Before you spend $500 on an SEO audit from an agency, run through this checklist yourself. Most of these checks take under 5 minutes each, and they'll tell you whether your site has fundamental problems or just needs fine-tuning.
Why You Should Audit Your Own Site First
Here's what happens when most small business owners hire an SEO agency: the agency runs the same automated scan that free tools can do, wraps the results in a nice PDF, and charges you $300-$2,000 for it. Half the recommendations are things you could have spotted yourself. The other half require technical knowledge — but you can't evaluate which recommendations are worth implementing if you don't understand the basics.
Running your own audit first means you'll know what your site's actual problems are before anyone tries to sell you solutions. You'll ask better questions, catch agencies that are padding their reports with non-issues, and save money by fixing the easy stuff yourself. I used this exact approach when growing BAiO from 0 to 3,600 users — and I never paid for a single audit.
Your title tag is the most important on-page SEO element. It's the blue link in Google results. Each page needs its own title that includes relevant keywords and describes what the page is about. "Home" or "Welcome" tells Google nothing.
The meta description is the gray text under your title in search results. Google doesn't use it directly for ranking, but it heavily influences click-through rates. A missing description means Google picks random text from your page — usually something unhelpful.
meta name="description". It should be 150-160 characters and include your main keyword naturally.The H1 is your main heading — the biggest, most prominent text on the page. Google uses it to confirm what your page is about. Having zero H1s means Google has to guess your topic. Having multiple H1s dilutes the signal. One per page, and it should closely match your title tag's topic.
<h1. You should find exactly one.After your H1, use H2s for main sections and H3s for subsections within those. Skipping levels (going from H1 directly to H4) or using headings just for styling tells Google your page structure is disorganized. Good heading hierarchy helps both Google and users understand your content.
Alt text describes your images to Google (which can't "see" images) and to screen readers for accessibility. Missing alt text means Google can't understand your images, and you're missing opportunities to rank in image search. Every image that conveys meaning should have descriptive, keyword-relevant alt text.
<img> tags. Each should have an alt="..." attribute with a real description, not just alt="".Google has used HTTPS as a ranking signal since 2014. If your site still loads on HTTP (no lock icon), you're being penalized in rankings and browsers are showing "Not Secure" warnings to visitors. Most hosting providers offer free SSL certificates now — there's no reason to skip this.
Google uses mobile-first indexing — it primarily crawls the mobile version of your site. If your site is broken, slow, or hard to navigate on a phone, your rankings suffer across all devices. Over 60% of searches happen on mobile, so this isn't optional anymore.
Page speed affects both rankings and user behavior. Google's Core Web Vitals measure loading performance, interactivity, and visual stability. Pages that take over 3 seconds to load see significantly higher bounce rates — people leave before they even see your content.
Broken links hurt user experience and waste Google's crawl budget. If you have links pointing to pages that don't exist, visitors hit dead ends and Google questions the quality of your site. Internal broken links are especially damaging because they're entirely within your control.
Robots.txt tells search engine crawlers which parts of your site they can and can't access. Without one, crawlers will try to access everything — including admin pages, staging content, or duplicate pages you don't want indexed. Having a well-configured robots.txt helps Google spend its crawl budget on your important pages.
A sitemap tells Google every page on your site that you want indexed. Without one, Google has to discover your pages by following links — and it might miss some. A sitemap is especially important for new sites, large sites, or sites with pages that aren't well internally linked.
If multiple pages on your site have the same or very similar content, Google doesn't know which one to rank — so it might rank neither. This commonly happens with product pages that share descriptions, location pages with identical text except the city name, or www and non-www versions of your site.
Google considers very short pages to be "thin content" — there isn't enough text for it to understand the topic or assess quality. Your homepage, service pages, and key landing pages should each have at least 300 words of unique, useful content. Blog posts should aim for 800 or more.
Internal links help Google discover your pages and understand how they relate to each other. If a page has no internal links pointing to it, Google may not find it at all. Every important page should be reachable within 3 clicks from your homepage, and related pages should link to each other naturally.
Structured data (schema markup) tells Google specific facts about your business, products, or content in a machine-readable format. Sites with structured data can get rich results in search — star ratings, prices, hours, FAQs displayed right in the listing. These enhanced listings get significantly higher click-through rates.
What to Do After Running This Checklist
If you found 3 or fewer issues, your site is in decent shape. Focus on creating content and building authority. If you found 4-8 issues, you have real optimization opportunities — each fix will likely improve your rankings. If you found 9 or more, your site needs foundational work before advanced SEO tactics will make a difference.
Pro tip: Don't try to fix everything at once. Pick the top 3 issues and fix those this week. Then do 3 more next week. Consistent small improvements beat one-time overhauls every time. That's how I grew a site from 0 to 3,600 users — weekly iteration, not a single big push.
If running through this checklist manually sounds tedious, you can also have AI do it for you. SimpleRank checks all 15 of these items (and more) automatically — just enter your URL and it emails you a prioritized report in about 60 seconds. It's the exact same analysis approach that produced real results for us, packaged so anyone can use it.

The biggest mistake small business owners make with SEO isn't choosing the wrong keywords or failing to build backlinks. It's ignoring the fundamentals. A site with strong titles, good meta descriptions, clean structure, fast loading, and mobile compatibility will outrank a site with none of those things — regardless of how much the competitor spends on advanced SEO tactics.
This checklist covers those fundamentals. Run through it, fix what's broken, and repeat every month. That's not a simplified version of SEO — for most small businesses, that is the SEO strategy. Everything else is optimization on top of a solid foundation.
