Smart marketing tools to fix your website’s biggest blind spots

There’s a point in every site owner’s life when something feels… off.

Pages load slowly. Visitors bounce. Forms don’t get filled. CTAs fall flat. But unless you’re lucky enough to have an in-house developer—or a budget for 40 SaaS subscriptions—you’re left guessing what to fix and how.

Good news: a smarter, cleaner website doesn’t require a rebuild or a dev agency. You just need the right tools—ones that diagnose what’s broken, surface what’s hidden, and make fixes that actually move the needle.

Here’s a curated stack of tools to help you find and fix the blind spots in your website—fast, without code, and without burning your weekend.

PageSpeed Insights

Fix: Slow load times and performance bloat

Speed is silent friction. If your site takes more than 3 seconds to load, users bounce—especially on mobile.

PageSpeed Insights, powered by Google’s Lighthouse engine, scans your site and tells you exactly what’s slowing it down. Unused JavaScript? Oversized images? Render-blocking resources? It flags them all.

Best of all, it gives you both a score and actual recommendations—with links to documentation.

Pro tip: After you optimize based on PSI’s suggestions, re-test every major page (not just your homepage). That’s where most issues hide.

Sentry

Fix: Errors you’ll never catch unless users complain

Your site might look fine… until something breaks quietly in production. Sentry monitors frontend errors, broken scripts, rate limit errors, or failed API calls in real time—so you don’t rely on angry customer emails to discover bugs.

It integrates with React, Vue, Angular, and vanilla JS. If something crashes, you’ll know:

• What failed
• Where it happened
• How many users it affected

Perfect for fixing issues before they cost you conversions.

Ahrefs

Fix: Invisible content and SEO blind spots

Before you even think about conversion, speed, or popups—ask yourself: can people find you?

Ahrefs marketing platform is your visibility radar. It helps you uncover which pages rank (or don’t), which keywords drive traffic to competitors, and where your site structure might be blocking Google from crawling pages correctly. Its Site Audit tool pinpoints broken links, slow-loading pages, duplicate content, and dozens of on-page SEO errors.

It’s not just for SEO geeks—marketers, product owners, and content teams use Ahrefs to:

• Spot underperforming landing pages
• Find high-traffic pages that lack CTAs
• Discover content gaps based on real search volume

If you want organic traffic that sticks, this is your first fix.

Formcake

Fix: Forms that don’t work—or never get submitted

Most forms break silently. They either don’t submit correctly, or they ask too much and scare people away.

Formcake gives you a backend for forms that just works—without plugins, clunky CMS add-ons, or JavaScript headaches. Add a POST endpoint to your form’s HTML, and you’re live. It’s perfect for JAMstack sites, microsites, and landing pages built without backend support.

Bonus: It’s GDPR-conscious, fast, and doesn’t require login portals just to see submissions.

Hotjar

Fix: UX friction and invisible confusion

Analytics tell you what users did. Hotjar tells you why.

With heatmaps, scroll maps, and screen recordings, Hotjar helps you understand how users actually behave on your site. You’ll spot where they hesitate, rage-click, ignore content, or miss the CTA altogether.

Instead of guessing why conversions are down, you’ll literally see the story play out.

Use it for:

• Watching how people use key landing pages
• Validating new layouts or CTAs
• Spotting bugs or broken UX patterns in real time

Polypane

Fix: Inconsistent designs across devices and accessibility issues

Your site might look perfect on your laptop. But what about a Chromebook, iPhone Mini, or someone browsing with high contrast mode?

Polypane lets you preview your site across multiple screen sizes and accessibility settings at once. Unlike browser dev tools, it shows everything—from how fonts scale to which buttons lack contrast or semantic structure.

Use it to:

• Find layout bugs before users do
• Meet accessibility standards without guessing
• Visualize your site like your users actually experience it

Your site doesn’t need a redesign. Just better tools.

Most “website problems” aren’t about tech debt or bad branding. They’re about clarity. Structure. Confidence. Speed.

These tools help you fix what’s broken—and unlock what’s hidden—without having to write code, rebuild everything, or cross your fingers.

Use them well, and your website becomes what it was meant to be: a machine that actually works for your users.
