Website Audit for Startups: What to Check Before Launch
A practical pre-launch website audit checklist for startup founders covering indexability, page speed, SEO, mobile, conversion paths, and trust signals.
# Website Audit for Startups: What to Check Before Launch
You've spent weeks building the product. The landing page went up Friday. Investors, friends, and a small wave of paid traffic are about to hit it on Monday.
This is the worst possible moment to discover that your signup form is broken in Safari, your hero image is 4.2 MB, or that Google can't index your homepage because someone left noindex in the meta tag from staging.
A pre-launch website audit is the cheapest insurance a startup can buy. It takes a few hours, not a few weeks. Below is a plain-English checklist of what to actually look at — the things that quietly kill conversions and rankings before they have a chance to start.

Why pre-launch audits matter more for startups
Established sites have buffers. They have brand searches, backlinks, returning visitors, and time to fix things. A startup site has none of that. Every visitor in your first month is borrowed — from an ad, a Product Hunt feature, a podcast, a cold email reply. If the page fumbles in the first three seconds, you don't get a second chance with that person.
The audit isn't about chasing a perfect Lighthouse score. It's about catching the handful of obvious failures that turn paid clicks into bounces and good content into pages Google never shows.
The 7 layers to check before you launch
Walk your site through these seven layers with fresh eyes — ideally on a device you've never used to view it before.
1. The "can Google even see this?" layer
This is the one that haunts new sites. Founders ship, run ads for three weeks, then notice they're nowhere in Google. The cause is almost always one of these:
- A leftover
from staging - A
robots.txtblocking everything withDisallow: / - A canonical tag pointing every page back to the staging URL
- A site behind HTTP auth that Googlebot can't reach
How to check, fast:
- Visit
yourdomain.com/robots.txtin your browser. If you seeDisallow: /with no other rules, you have a problem. - View source on any page, search for
noindexandcanonical. The canonical URL should match the live domain, not staging or localhost. - Open Google Search Console, submit your sitemap, and use the URL Inspection tool on your homepage. It tells you plainly whether the page is indexable.
If you do nothing else from this list, do this. Indexing problems compound silently.
2. The speed layer
Speed is the one technical metric that maps directly onto money. Slow pages bounce more, convert less, and rank lower. Google's Core Web Vitals — Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift — are the practical benchmarks to hit.
The most common startup speed-killers, in order of how often they show up:
- Unoptimized hero images. A 3 MB PNG of your product screenshot is the single biggest offender. Convert to WebP, target under 200 KB.
- Tag-bloat. Six analytics tools, two chat widgets, a heatmap, an A/B testing library, and a cookie banner all loading on page one. Pick the two you'll actually look at this quarter and remove the rest.
- Webfonts loading from three sources. Self-host one font family. Use
font-display: swap. - A hero video that autoplays. Replace with a poster image until the user scrolls.
Run your homepage through PageSpeed Insights once and fix the top three "Opportunities" it lists. That covers 80% of the win.

3. The content and SEO basics layer
You don't need a full SEO strategy before launch. You need pages that aren't actively confusing to search engines.
The minimum checklist:
- Every page has a unique
under 60 characters - Every page has a unique meta description under 160 characters
- Exactly one
per page, in human language - Image
alttext on anything that conveys meaning (decorative images can stay empty) - A real
favicon.ico - An XML sitemap at
/sitemap.xml, linked fromrobots.txt - No placeholder copy. Search "lorem ipsum" across your site. Search "click here." Search your internal feature nicknames.
Google's guidance on helpful content is the lens to apply: write pages for the person reading them, not for a keyword. A homepage that says "AI-powered next-generation platform for forward-thinking teams" tells nobody anything. A homepage that says "Schedule social posts for your Shopify store in under 5 minutes" tells everybody everything.
4. The trust layer
Startups have zero brand equity at launch. Every visitor is silently asking: is this real, will my card get stolen, will support answer if something breaks. Trust signals answer those questions before they're asked.
Walk your homepage and check for:
- A visible company name and registered address in the footer
- A working contact method that isn't just a chat widget (an email address is fine)
- Privacy and terms links that load and aren't templated boilerplate with
[YOUR COMPANY NAME]still in them - Real customer logos or testimonials — or none, if you don't have any. Empty space beats fabricated proof.
- HTTPS on every page, with no mixed-content warnings
- Pricing that exists. "Contact us for pricing" on a self-serve product reads as a red flag to early-stage buyers.
5. The mobile layer
More than half your launch traffic will be on a phone. Test on an actual phone, not just Chrome's device emulator.
Things that break on real phones but pass in DevTools:
- Tap targets that work with a mouse cursor but are too small or too close together for a thumb
- Hero text that gets cut off behind a sticky header on mobile
- A signup form that triggers the keyboard and then scrolls in a way that hides the submit button
- A cookie banner that covers 40% of the screen with no easy dismiss
- An autoplay video that drains battery and triggers iOS to lower the volume
Open the site on your phone in airplane mode for a second, then re-enable cellular. That simulates the "metro station signup" experience most of your real users will have.
6. The conversion path layer
You can have a fast, indexed, trustworthy site that still converts nothing because the path from "land" to "do the thing" is broken or hidden.
Trace it yourself, click by click:
- Land on homepage. Where is the primary CTA? Is it above the fold? Does it say what happens when you click it?
- Click the CTA. Does the form ask for the minimum it needs, or for your job title, company size, and phone number on step one?
- Submit the form. Does a confirmation email arrive within 60 seconds? Does it come from a real domain (
noreply@yourstartup.com) or frommailer@sendgrid.net? Inbox or spam? - Click any link in that email. Working page or 404?
Then do it again on a phone. Then again as an incognito user who isn't logged in to anything.
This is the most-skipped step in pre-launch audits, and the one that costs the most.
7. The "what happens when things go wrong" layer
Real users do weird things. They click old links, mistype URLs, paste broken share links from Slack. Your error states are part of your product.
- Visit
yourdomain.com/this-page-does-not-exist. Is the 404 useful, with a search box and links back to main pages, or a wall of text saying "Not Found"? - Submit your signup form with an obviously invalid email. Does it explain what's wrong, or silently fail?
- Try a card that gets declined. Does the error message reach the user, or does the page spin forever?
- What does the page look like if a third-party script (analytics, chat widget) fails to load? Does the rest of the site still work?

A short walkthrough: a real pre-launch audit
Here's how this plays out. A solo founder building a small SaaS for freelance bookkeepers asks for a 30-minute review the day before her Product Hunt launch.
Indexability first. Her robots.txt is fine. But the homepage canonical points to https://staging.bookkeeperhq.com — leftover from dev. A 30-second fix that would have kept the entire site out of Google for weeks.
Speed next. The hero is a 2.8 MB JPG of her product UI. Compressed to WebP at 180 KB, LCP drops from 4.1s to 1.6s on a simulated 4G connection.
Content layer. The pricing page title is just "Pricing." Changed to "Pricing — Bookkeeping Software for Freelancers | BookkeeperHQ." Three other pages had identical meta descriptions copy-pasted from the homepage.
Trust layer. No privacy policy link in the footer. She has one written — it's just not linked. Two minutes.
Conversion path. The signup confirmation email goes out from info@bookkeeperhq.com, but the domain doesn't have SPF or DKIM records, so Gmail flags it as spam. We add the records via her DNS provider. Now it lands in inbox.
Total time: 47 minutes. Issues found: 11. Issues fixed before launch: 9. The two unfixed — a slow blog page, a slightly oversized webfont — are noted for next sprint.
That's what a useful pre-launch audit looks like. Not exhaustive. Specific.
Structured data: a small bonus win
If you're publishing a blog or long-form content, add Article structured data to those pages. Google's documentation spells out the required fields — headline, author, datePublished. Fifteen minutes sitewide if your CMS supports it, and it makes your content eligible for richer search appearances.
Not a launch-day priority. Worth knowing about for week two.
What to skip (for now)
Some things matter eventually, not at launch. Don't let them block you:
- Schema markup on every page type. Articles are worth it. Most others can wait.
- Perfect Lighthouse scores. 90+ on mobile is plenty. Chasing 100 is a multi-week project.
- Heavy A/B testing infrastructure. You need traffic before you can test anything meaningfully.
- A blog with 20 posts on day one. One good post and a real plan beats twenty thin ones.
- Internationalization. Ship in one language. Translate when you have demand.
The pre-launch audit is about removing landmines, not polishing chrome.

A 20-minute self-audit checklist
If you only have 20 minutes before launch, do these in order:
- View source on the homepage. No
noindex, canonical points to the live domain. (2 min) - Visit
/robots.txtand/sitemap.xml. Both exist and look right. (1 min) - Run the homepage through PageSpeed Insights on mobile. Note the LCP. (2 min)
- Compress and replace the hero image if it's over 300 KB. (3 min)
- Confirm every page has a unique title and meta description. (4 min)
- Click your primary CTA. Submit the form. Check the email arrives in inbox, not spam. (3 min)
- Open the site on your phone. Try to sign up with one thumb. (3 min)
- Visit a fake URL. Confirm the 404 page is useful. (1 min)
- Footer check: privacy, terms, contact, address. (1 min)
That's the minimum. Anything beyond is bonus.
Run a free audit before you ship
You can do all of this manually, and on a small site you probably should at least once. After the first pass, an automated audit catches the things you'll otherwise miss — the broken canonical you fixed last week and accidentally reverted, the new page someone added without a meta description, the third-party script that quietly tripled your page weight.
Run a free website audit on FreeSiteAudit — paste your URL, get a plain-English report covering indexability, speed, content, mobile, and trust signals in under two minutes. No signup required for the first scan. If you're a SaaS startup specifically, the startup industry checklist covers patterns we see most often. For deeper fixes, the Core Web Vitals guide and the meta tags walkthrough cover the two areas startups most commonly get wrong.
The goal isn't a perfect site. The goal is a site that doesn't get in its own way on launch day.
