Website Audit Checklist: 27 Things That Make or Break Your Leads in 2026

A website audit checklist is a list of the things that decide whether a visitor becomes a lead: speed, mobile usability, a clear call to action, a working form, findability on Google and in AI assistants, trust signals and fast follow-up. Check the 27 items below, then fix the ones that block leads first.

Most owners judge a website by how it looks. Buyers judge it by how fast it answers their question and how easy it is to reach you. A beautiful site that loads slowly, hides the phone number or sends form fills into an unwatched inbox is a leaky bucket with a nice paint job.

Work through this list with your site open on your phone. Or let our free website audit run the automated checks for you, then use this guide to understand what it finds.

What Does a Website Audit Actually Check?

A website audit is a structured review of how well your site turns visitors into leads, and how easily search engines and AI assistants can find, read and trust it. A useful audit doesn’t stop at a score. It tells you what to fix first and why. Every item below is also a requirement for website design built for leads, so the list doubles as a brief if you ever rebuild.

We group the 27 checks into the same five categories our free audit scores:

Is Your Website Built to Turn Visitors Into Leads?

Conversion problems cost you the most, because they waste traffic you already paid for. Start here.

1. A tap-to-call phone number in the header. On mobile, your number should be a link that dials with one tap. If buyers have to copy and paste it, some won’t bother.
2. One clear primary call to action above the fold. Use a verb and a benefit, like “Get My Free Estimate.” Buttons that say “Submit” or “Learn More” tell the visitor nothing.
3. A short form you test every month. Keep a first-contact form to five fields or fewer. Fill it out yourself and confirm the message arrives. A plugin update can break a form without anyone noticing, so test on a schedule.
4. A real reason to reach out now. A free quote, inspection, audit or calculator gives a visitor something to gain today. Skip fake countdown timers. Buyers see through them, and they erode trust.
5. Proof near the top of the page. BrightLocal’s Local Consumer Review Survey 2026 found 97% of consumers read reviews for local businesses, and 47% won’t use a business with fewer than 20 reviews. Show real reviews, licenses and photos of real work.
6. Privacy and consent done right. Link your privacy policy near every form. If you plan to text leads, add a separate, unchecked SMS consent box with “Reply STOP to opt out” language.
7. Follow-up that starts the moment a form arrives. When researchers sent web leads to 2,241 U.S. companies, only 37% responded within an hour, and 23% never responded at all (Harvard Business Review, 2011). Your website can’t close a lead nobody answers. Our guide to speed to lead explains why minutes matter.

Is Your Site Fast Enough, or Is It Melting on Mobile?

Speed is a lead problem, not just a tech problem. Google’s 2017 research found that 53% of mobile site visits were abandoned when a page took longer than 3 seconds to load (Think with Google). Google’s Core Web Vitals give you three targets, measured on real visitors (web.dev).

8. Largest Contentful Paint (LCP) of 2.5 seconds or less. LCP measures how long the main content takes to appear. A heavy hero image or autoplay video is the usual culprit.
9. Interaction to Next Paint (INP) of 200 milliseconds or less. INP measures how quickly the page responds when someone taps a button or opens a menu. Piles of scripts and plugins slow it down.
10. Cumulative Layout Shift (CLS) of 0.1 or less. CLS measures how much the page jumps while it loads. Images without set dimensions and late-loading banners cause most of it.
11. A true mobile layout. Text you can read without zooming, buttons big enough for a thumb, no sideways scrolling and no pop-up covering the page on load.
12. Compressed images and click-to-load video. Serve modern formats like WebP or AVIF at the size they display. Show videos as a thumbnail that loads the player only when someone presses play.

In plain terms Test your homepage and your busiest service page in Google’s free PageSpeed Insights tool on the mobile setting. If the main content takes longer than about 2.5 seconds to appear, fix that before you buy more traffic.

Can Google Find and Understand Every Page?

SEO checks make sure the right pages show up for the right searches. None of them require tricks. They require clarity.

13. Every important page is indexable. A stray “noindex” tag or a robots.txt rule that blocks Googlebot can make a page invisible. Both can slip in during a redesign or a rushed launch.
14. A unique title tag and meta description on each page. Keep titles to about 60 characters with the main service near the front, and write descriptions that give a reason to click.
15. One H1 per page that says what you do. “Water Heater Repair in Sacramento” beats “Welcome to Our Website” every time.
16. An XML sitemap submitted in Google Search Console. It helps Google discover new pages, and Search Console shows which ones have problems.
17. A dedicated page for each core service. One page that lists everything you do can’t rank well for any single service. Add location pages only when each has genuinely unique content. Google’s spam policies warn against thin doorway pages that only swap the city name.
18. A complete Google Business Profile with consistent details. Your business name, phone and website should match everywhere they appear. Our guide to local SEO for contractors walks through the profile step by step.
19. Healthy internal links and a helpful 404 page. Link related services to each other, fix broken links, and make sure a missing page returns a real 404 with a path back to your services.

Will AI Assistants Recommend Your Business?

Search is no longer just a list of blue links. BrightLocal’s 2026 survey found 45% of consumers now use AI tools like ChatGPT for local business recommendations, up from 6% a year earlier. And the Pew Research Center found Google users clicked a traditional result on 8% of visits when an AI summary appeared, versus 15% when one didn’t (2025). If AI tools can’t read your site, you’re left out of the answer.

20. Important content in the HTML, not hidden behind JavaScript. Many AI crawlers don’t run JavaScript, according to Vercel’s analysis of AI crawler traffic. If your services, FAQs or prices appear only after scripts load, those crawlers may never see them.
21. Answer-first writing. Open each key page with a two- or three-sentence answer to the question it targets, then go deeper. Use question-style headings that match how people actually ask.
22. Organization schema that describes your business. Structured data (JSON-LD) should state your business name, logo, website, contact details and official profiles, written the same way everywhere.
23. A robots.txt file that lets the right crawlers in. Search and answer crawlers such as Googlebot, Bingbot, OAI-SearchBot, Claude-SearchBot and PerplexityBot shouldn’t be blocked from your public pages. Allowing AI training crawlers is a separate business decision.
24. Fresh, dated, sourced content. Show an “Updated” date when you make real changes, and link to the sources behind your numbers. In a 2025 study, Ahrefs found pages cited by AI assistants were fresher on average than pages in regular search results.

Is Your Technical Foundation Solid?

25. HTTPS on every page. Your site should load securely, and the plain “http://” address should redirect to “https://” in a single hop.
26. Current software and basic security headers. Keep your CMS, theme and plugins updated, remove plugins you don’t use, and ask your developer about headers like HSTS and X-Content-Type-Options.
27. Analytics and conversion tracking. Track form fills, calls and bookings, not just visits. If you can’t see which pages produce leads, you’re guessing where to spend.

Which Website Fixes Should You Make First?

Not every failed check deserves the same urgency. Work in this order:

If the fixes add up to a rebuild, that’s a website design conversation. If they’re mostly about visibility, start with SEO and AI search optimization.

Should You Audit Your Website Yourself or Use a Tool?

Do both. Tools catch technical issues in minutes. A person catches what tools can’t judge, like whether your headline speaks to the right buyer.

• Do it yourself: use PageSpeed Insights for speed, Google Search Console for indexing, and your own phone for the real buyer experience. Call your business after hours and submit your own form. You’ll see and hear exactly what a buyer gets.
• Use our free audit: the Butter Score website audit scores conversion, SEO, speed and mobile, AI readiness and technical health, then lists what to fix first. Its crawler, ButteredScoreBot, reads only your public homepage and four public files, and never touches your admin area.

Home service pros can pair the audit with the Missed Call Revenue Calculator. Law firms should read our guide to AI intake for law firms. You’ll find more industry playbooks on our home services and law firm marketing pages.
