7 Small Website Mistakes That Are Costing You Money

Your website looks fine. The design is clean. The content reads well. The pictures are pretty. And yet, something is wrong. Visitors aren't converting. Leads are dropping. You're getting traffic but not results. And you're beginning to suspect the problem isn't big enough to see.

You're right. The problem is almost never big enough to see. It's the small things. A favicon missing. An image that takes 14 seconds to load. Alt text that's empty. A form that goes nowhere. A page title that tells Google nothing. These individual mistakes seem trivial. Collectively, they're a quiet disaster that can cost thousands of pounds in lost revenue.

Here are seven specific, fixable mistakes we encounter constantly on Squarespace sites. Each one costs money. Each one is fixable within an hour. Each one is completely preventable if you know what to look for.

Mistake 1: Uncompressed Images That Kill Your Load Speed

A wedding photographer calls us after losing a booking. She'd been meeting a couple at a café to discuss their wedding. They'd found her through Instagram, loved her portfolio, asked for her website. She gave them the URL. They pulled it up on a phone. And then they waited. And waited. The hero image appeared in stages, like a Polaroid developing, except nobody thought this was charming. Fourteen seconds to load.

The couple's enthusiasm evaporated in real time. They said they'd think about it and never called back. She lost the booking over load time.

Here's what was happening: her hero image was 8.7 megabytes. She'd uploaded it directly from Lightroom at full resolution because she wanted her work to look perfect. Understandable. Catastrophic. The research is unambiguous: 40% of visitors abandon sites that take longer than three seconds to load. For every additional second beyond that, conversion rates drop by roughly 4.4%. This photographer was asking potential clients to wait nearly twelve seconds. Most didn't wait.

The fix took an hour. We resized every image to 2,500 pixels on the longest edge (more than enough for any screen) and compressed them using a tool called TinyIMG. The hero image went from 8.7MB to 340KB. Visually, virtually indistinguishable. Her homepage load time dropped from 14 seconds to 2.1. She booked two weddings the following month.

What to do right now: Open your Squarespace site and go to any page with large images. Check the file sizes. If anything is over 500KB for a banner or 250KB for an in-page image, compress it. Use JPG format for photographs (PNG for graphics with transparency). Tools like TinyIMG, Squoosh, or JPEGmini will do the compression. This isn't optional. Your conversion rate depends on it.

Mistake 2: Empty or Useless Alt Text on Every Image

A bakery in south London had invested in beautiful food photography, written thoughtful product descriptions, built a genuinely solid Squarespace site. And couldn't understand why their website wasn't generating orders.

A food blogger reached out. She's visually impaired and uses a screen reader to browse the web. She'd heard about the bakery from a friend and wanted to feature it in a roundup of London's best independent bakeries. She tried to access the website and couldn't make sense of it. The screen reader was announcing images as "IMG_4521.jpg" and "DSC_0073_final_v2.jpg" instead of "Rosemary and sea salt sourdough loaf" or "Selection of pastries on a marble countertop." The food blogger moved on to another bakery. The feature—which would have reached about 15,000 readers—went to someone else.

The bakery lost the press opportunity because of something they didn't even know was a problem. Their alt text was empty, or auto-populated with file names. And more broadly, around 24% of the UK population have a disability. This wasn't a niche concern. It was a quarter of their potential audience they were excluding.

Alt text does two things: it describes images for screen reader users, and it tells search engines what images contain. Both matter. Empty alt text means you're invisible to both audiences.

What to do right now: Go through every image on your site. Write actual, descriptive alt text. Not keyword-stuffed SEO alt text, but genuine descriptions of what's in the image, written as if for someone who can't see it. For the pastry photo: not "pastries" but "Selection of croissants and pain au chocolat on a marble countertop." This takes time. It's worth it. You're literally making your business visible to millions of people you're currently excluding.

Mistake 3: Missing or Generic Meta Titles and Descriptions

An accountancy firm in Manchester, thirty years in business, excellent reputation, hired a designer to build a new Squarespace site. The designer did a beautiful job visually. And then, for the next twelve months, the site generated precisely zero organic search traffic. Not low traffic. Zero.

The problem was threefold. First, every page had the same meta title: "Home - [Company Name]." The designer hadn't customized the SEO titles for individual pages, so Google had no way of knowing what each page was actually about. Second, the site had no blog, no ongoing content for search engines to index. The firm had decades of expertise in tax planning and payroll, but none of it existed on their website. Third, every heading on every page was an H1. It was like a book where every sentence was a chapter title.

Google's crawlers use meta titles, heading structure, and content to understand what a page is about. With identical meta titles across every page and no unique content, the site was giving Google nothing. It was a beautiful house with no address.

The fix took a few weeks. We wrote unique, keyword-informed SEO titles and meta descriptions for every page. We restructured headings into a proper hierarchy. We started a monthly blog with practical articles on topics their clients were actually searching for. Within six months, the site was ranking on page one for several local search terms. Within a year, organic traffic was generating 30% of their new client enquiries.

What to do right now: Click through every page of your site. Check the SEO panel in Squarespace (settings cog icon, scroll to SEO). Make sure every page has a unique SEO title that includes a relevant keyword and your business name. Write a meta description of about 150-160 characters that describes what the page is actually about. Most sites leave these blank or filled with placeholder text. They shouldn't. These fields tell Google and potential visitors what your page is about.

Mistake 4: Mobile Navigation That's Impossible to Use

A yoga studio owner built her Squarespace site on a lovely wide desktop monitor. It looked fantastic. Then she checked her analytics: 73% of her visitors were on mobile, and the mobile bounce rate was 81%. More than four in five people arriving on their phone were leaving almost immediately.

The issue: she'd never looked at her site on a phone. On mobile, carefully chosen hero text was being displayed at the same massive size as desktop, pushing the call-to-action button below the fold. Her class schedule, gorgeous in a three-column layout on desktop, stacked into a single column on mobile with such large spacing that you had to scroll forever to find Tuesday's timetable. Background images cropped awkwardly, cutting off important details.

Over 70% of web traffic is mobile. Google prioritizes mobile-first indexing. Yet most DIY Squarespace builders design almost exclusively on desktop and treat mobile as an afterthought. Squarespace 7.1's Fluid Engine does handle responsive design, but "automatic" doesn't mean "optimal." You need to actively design for mobile.

What to do right now: Pull out your phone and actually use your website. Tap every link. Read every page. Try to book an appointment, buy a product, find contact details. Do this on a bus, in a queue, in real-world conditions. Then switch to the mobile view in Squarespace's editor and adjust what doesn't feel right: reduce text sizes, tighten spacing, set image focal points, hide blocks that aren't pulling their weight on a small screen. Squarespace's Block Hiding feature lets you hide specific blocks on mobile without any code. Use it.

Mistake 5: Broken Links and Outdated Information

You have a blog post from three years ago that links to a page that no longer exists. That page links to an external site that's now dead. Your contact form has an email address that's no longer monitored. Your hours say "Monday to Friday, 9am-5pm" but you changed to a four-day week six months ago and never updated the site.

Each of these is a small thing. Collectively, they send a clear message: this site is abandoned. If your information is wrong or your links are dead, how much attention are you really paying to your business? Broken links also actively hurt your SEO. Google's crawlers follow links to assess a site's structure and importance. Dead links waste crawl budget on pages that don't exist.

What to do right now: Run your site through a link checker tool like Google's Search Console or a third-party tool like Broken Link Checker. Fix anything that's actually broken (external links to dead websites, internal links to pages that no longer exist). Then manually audit the most important pages: your homepage, your contact page, your main service/product pages. Make sure all information is current. If you offer a free consultation but that page says "coming soon," fix it. If your hours have changed, update them. If you mention something you don't do anymore, remove it.

Mistake 6: Forms That Go Nowhere

An estate agent spent £3,000 on a new Squarespace site. Beautiful design, great photography, prominent contact forms on every listing page. They launched, promoted it, and waited. After three weeks with no form submissions, not one, they called us in a panic.

The problem: the form block's storage settings hadn't been configured. In Squarespace, when you add a Form Block, you have to tell it where to send submissions—either to your email address or to Squarespace's built-in storage. If you don't configure this, the form appears on the page, looks perfectly normal, and does absolutely nothing when someone fills it in. The visitor fills out their name, email, and message, clicks submit, and the enquiry vanishes into the void. No error message. No indication that anything went wrong. Just silence.

Three weeks of enquiries. Gone. Potential buyers and sellers who thought they'd made contact and were waiting for a response that would never come. It's the kind of mistake that takes thirty seconds to fix and an unknown amount of business to recover from.

What to do right now: Go to every form on your site. Click on the form block, open the Storage tab, and make sure it's connected to your email address. Then do something critical: submit a test enquiry yourself. Fill in the form with test data, hit submit, and check that the email actually arrives. Do this every time you add or edit a form. If you set up a new contact form and don't test it, you have no idea whether it's working. Test it.

Mistake 7: No Clear Call to Action

A visitor lands on your homepage. They scroll through the content. It's all relevant, well-written, exactly what they were looking for. And then they reach the bottom of the page and... what? There's no obvious next step. No "Book Now" button. No "Get in Touch" form. No "Learn More" link. They could contact you, theoretically, but how? Your contact information isn't visible. They'd have to hunt for it. So they don't. They close the tab and Google someone else who makes it easier.

Every page should have a clear call to action. Not buried. Not subtle. Clear. Visible. Specific. "Book Now." "Get a Quote." "Join Our List." "Schedule a Call." Something that tells the visitor exactly what you want them to do next.

And it should appear multiple times. Once at the top of the page (in the hero section or near it). Once in the middle (after you've made your case). Once at the bottom (for people who've read everything and are ready to convert). If it's important, don't make people hunt for it.

What to do right now: What's the main action you want visitors to take? Figure that out. Make sure it's visible on every page. If it's booking a call, have a prominent "Schedule a Call" button. If it's buying a product, have a clear "Add to Cart" button. If it's an email signup, have a signup form that's visually obvious. And test it: can a first-time visitor find your primary CTA within three seconds of landing on your page? If the answer is no, make it more prominent.

Why These Small Things Add Up

None of these mistakes are dramatic. None of them will destroy your site by themselves. But they accumulate. They stack up like hairline cracks in a wall. One slow-loading image isn't catastrophic. But combined with empty alt text, a missing favicon, a form that goes nowhere, and outdated contact information, they create an impression: this site isn't trustworthy, this business isn't professional, I should find someone else.

The gap between "good enough" and "actually working" is often just these seven things. No major redesign. No new strategy. No expensive overhaul. Just tiny details, each one fixable in minutes, that collectively determine whether your site converts or doesn't.

The most valuable thing you can do for your website, right now, today, is to experience it as a stranger would. Clear your cache. Open it on a phone you don't usually use. Ask someone who's never seen it to find your contact details. Try to book an appointment, buy a product, do the thing your site exists for. The mistakes you find won't be glamorous. But fixing them might be the most profitable hour you've ever spent.
