5 Sales Page Template Mistakes That Cost Time, and the Fixes

A sales page template should save you time. These five mistakes do the opposite: they send you back to rewrite, answer the same email ten times, or lose a buyer who was nearly ready. They come from common sense and published guidance, not from a count of any kind, so treat the order as a suggestion.

Each mistake below has a cost and a fix. Lesson 4.2 builds the fixes into the process, so you avoid them from the start: A page that sells while you sleep.

Most sales page problems come from a vague buyer, unchecked AI text, missing basics or an untested phone view, and each has a quick fix.

Mistake 1: Writing for everyone

What it looks like. "Our solution helps businesses grow." Nobody feels spoken to.

Why it costs time. You rewrite the headline five times because there is no buyer to test it against.

The fix. Write one sentence naming one person and their situation. Then write the headline for that person only. If you cannot describe them, talk to three customers before you write another word. Use the phrases they use.

Mistake 2: Letting AI invent things

What it looks like. A testimonial from "Sarah, a happy customer", a claim that "thousands of people love this", or a guarantee you never offered.

Why it costs time. You have to find and remove every invented line, and if one slips through, you may have a trust or legal problem. In the United States the FTC has a final rule on fake reviews and testimonials, which covers reviews by people who do not exist, including AI generated ones, and reviews that misrepresent the writer's experience. Rules differ by country, and I cannot give legal advice, so check the rules where you sell.

The fix. Tell AI to use only facts you supply, and to mark anything it is unsure of. Then read the draft with a pen, and strike every claim you cannot back. Where you have no proof yet, describe how you work instead.

Mistake 3: Leaving out the basics

What it looks like. No price, no delivery details, no word about what happens after paying, no contact route.

Why it costs time. Buyers email to ask, or quietly leave. You answer the same questions again and again, and some people never ask.

The fix. Add a short block called "What you get and what happens next". Put in the price, what is included, how and when it arrives, how to get help, and your refund or return terms if you have them. Keep the wording the same everywhere you mention it, including in the receipt or confirmation message.

Mistake 4: Too many choices

What it looks like. A menu with eight links, three different offers and four different buttons.

Why it costs time. The page gets longer and the message gets blurrier. You spend your effort designing navigation instead of fixing the offer.

The fix. One offer, one button, repeated. Remove the main menu from the sales page if your builder allows it, or at least trim it. If you have more offers, give each its own page.

Mistake 5: Never opening it on a phone

What it looks like. A page that looks neat on your laptop and is cramped on a phone: tiny text, a button that is hard to hit, pale grey text on a white background.

Why it costs time. A lot of visitors may arrive on a phone, so a failure there can waste all your other work. You also find out late, when someone tells you.

The fix. Open the page on a real phone before you share it. Three checks with published guidance behind them:

• WCAG asks for a contrast ratio of at least 4.5 to 1 for normal sized text, so use dark text on a light background, or the reverse.
• Web.dev suggests tap targets of around 48 pixels.
• Google says the mobile version of a page should carry the same primary content as the desktop one, so do not hide your price or terms on mobile.

A bonus mistake: one description for every page

Many page builders pre-fill the same description for every page. Google's documentation says identical or similar descriptions on every page are not helpful, and recommends unique ones that accurately describe the specific page. Write a sentence for your sales page that states what it offers and to whom.

How to find your own mistakes

Ask one person who fits your buyer to read the page and tell you what they think it sells and what they would do next. If they cannot answer, the page has one of these problems. A second option is to read the page aloud and mark every place you hesitate.

For a structured way to rebuild the page, see A framework for a sales page template. For a fuller walk-through, see A complete guide to a sales page template.

A short routine to catch them early

You can catch most of these in thirty minutes before launch. Read the page aloud once for mistake 1, asking who it is for. Search the text for every name, number and quote for mistake 2. Look for the price, delivery and support lines for mistake 3. Count the buttons and links for mistake 4. Then pick up your phone for mistake 5.

Do the routine again after every large edit, not only the first time. Pages drift: a quick change to the headline can leave the button wording out of step, or a new paragraph can push the price out of sight on a small screen. A short checklist taped near your desk is more reliable than memory.

Questions people ask

Which mistake is the most expensive?

Usually the first, because a vague buyer weakens every other part. Fix it before anything else.

Can I let AI write the whole page if I check it?

Yes, as a first draft. The checking step is where you make the page true.

Do I need a lawyer for a sales page?

Not for a simple one, but if you sell something regulated, or make claims about health or money, get proper advice.

How do I know if the phone view is fine?

Read the page with one thumb on a real phone, tap the button, and ask a friend to do the same.
