How to Fix the 7 Costliest Website Mistakes in Under an Hour

A few quick tweaks can be the difference between winning a customer and losing them forever. Below are the seven most common (and expensive) website mistakes I see—and exactly how to fix each one in 60 minutes or less.

1. Slow Load Times

Why it’s costly: Google finds that 53 % of visits are abandoned when a mobile site takes longer than three seconds to load. Google Business

60-minute fix

1. Run your URL through PageSpeed Insights (free).
2. Compress every image it flags with TinyPNG or ShortPixel.
3. Delete unused plugins / scripts.
4. Enable built-in “lazy loading” in your CMS (one toggle in WordPress).

2. Not Mobile-Friendly

Why it’s costly: Mobile now accounts for 64 % of all web traffic in 2025. Exploding Topics

60-minute fix

1. Open your site on a phone—menu, buttons, and forms should be tap-friendly.
2. In WordPress or Wix, switch to a responsive theme; most adjust automatically.
3. Increase body text to at least 16 px and add 1.5 em line-height.

3. Missing HTTPS (No SSL)

Why it’s costly: Google gives HTTPS sites a ranking boost and users trust them more—lack of security drives up bounce rates. mettevo.com

60-minute fix

1. Buy or enable the free Let’s Encrypt SSL at your host.
2. Force HTTPS with a plugin (Really Simple SSL) or host toggle.
3. Test the padlock—no mixed-content warnings.

4. No Clear Call-to-Action (CTA)

Why it’s costly: 70 % of small-business B2B websites have no CTA at all—and leave leads on the table. Sixth City Marketing

60-minute fix

1. Decide the one action you want (Book a Call, Get a Quote, Buy Now).
2. Add a contrasting button in the hero section and again halfway down.
3. Use action verbs: “Schedule My Consultation” outperforms “Submit.”

5. Outdated or Unattractive Design

Why it’s costly: 38 % of people stop engaging if a site’s layout is unattractive. wix.com

60-minute fix

1. Swap any low-res or cheesy stock photos for clean, high-quality images.
2. Adopt a modern color palette (two main colors + plenty of white space).
3. Replace dated fonts with a free Google Font like Inter or Lato.

6. Unoptimized Images

Why it’s costly: Images are the #1 cause of bloat and slowdowns.

60-minute fix

1. Export JPGs for photos, PNG/SVG for logos & icons.
2. Keep hero images under 200 KB; inline graphics < 50 KB.
3. Use WebP (one-click in most optimizers) for 25–35 % smaller files.

7. Missing Basic SEO (Titles & Meta Descriptions)

Why it’s costly: Pages without keyword-rich titles rarely rank—even for brand searches.

60-minute fix

1. Install Yoast (WP) or built-in SEO panel (Squarespace/Wix).
2. For each page, write a <60-character title with a primary keyword + city (e.g., “Plumber in Miami | ABC Plumbing”).
3. Add a 120–150 character meta description that ends with a call-to-action.
