10 Website Mistakes That Cost You Customers, and How to Fix Each One

Here is a typical version of a call I get often. An interior designer in Vashi says her website gets a few hundred visitors a month, according to her analytics, but the enquiry form has produced almost nothing for half a year. We open the site on her phone together, and within two minutes the cause is visible: the form’s submit button sits below a cookie banner that never closes on small screens. Nobody could press it.

That is the pattern with most underperforming websites. They are not ugly or broken in an obvious way. They leak customers through small mistakes that the owner never sees, because the owner looks at the site on a desktop, already knows what the business does, and never fills in the form. This piece walks through the ten mistakes I find most often on small-business sites in Mumbai and Navi Mumbai, what the data says about each, and one fix for each.

1. The site is slow on a phone

This is the leak I find most often, and the one owners underestimate, because their office Wi-Fi and new laptop hide it. Google’s Core Web Vitals give a fair yardstick: the main content should appear within 2.5 seconds (Largest Contentful Paint), the page should react to a tap within 200 milliseconds (Interaction to Next Paint), and the layout should not jump as it loads (Cumulative Layout Shift of 0.1 or less). Google measures these at the 75th percentile of real visits, so the slowest quarter of your visitors decides your score.

Most sites miss. The HTTP Archive’s 2025 Web Almanac performance chapter found that only 48% of websites passed all three on mobile, against 56% on desktop.

Loading is the weakest link, and the same chapter shows why. On 76% of mobile pages the biggest element on screen is an image, usually a hero banner. Many sites then make it worse: 62% of mobile pages had at least one image without set dimensions, which causes layout jumps, and around 16 to 17% lazy-loaded the main image, which delays exactly the thing visitors are waiting for.

Does speed affect money? The best-known study is Milliseconds Make Millions (Deloitte for Google, March 2020). Across retail, travel, luxury and lead-generation brands in Europe and the US, a 0.1-second improvement in mobile speed went with an 8.4% rise in retail conversions and an 8.3% improvement in bounce rate on lead-generation information pages. Treat those as directional: it is a four-week, Google-commissioned study of large Western brands, not Indian small businesses. The direction matches what I see, though.

2. It was designed on a desktop and visited on phones

Indian internet use is overwhelmingly mobile. TRAI’s subscription data for June 2026 counted 1,087.50 million broadband subscriptions, of which 1,039.78 million were wireless and 47.71 million wireline. That is roughly 95.6% wireless (my calculation from TRAI’s figures). Plenty of those people also own a laptop, but the phone is where most first visits to a local business happen.

Google sees it the same way. Its mobile-first indexing documentation says it uses the mobile version of a site’s content, crawled with a smartphone agent, for indexing and ranking, and that content shown only on desktop is not used. So a mobile layout that hides your service list behind a menu nobody opens, or drops a section to “save space”, can cost you in search as well as with visitors.

The usual mobile failures I see are small text that needs zooming, buttons too close together to tap accurately, pop-ups that cover the whole screen, and tables of rates that scroll off the side of the page.

3. Visitors cannot tell what you do in ten seconds

People give a new page very little time. Nielsen Norman Group’s analysis of dwell times (2011, based on 2010 Microsoft Research data covering 205,873 pages) found that users often leave web pages within 10 to 20 seconds, and that the first 10 seconds decide whether they stay. Their advice was blunt: communicate your value proposition within 10 seconds if you want minutes of attention.

The data is old, but I have not seen anything since that suggests people became more patient. On small-business sites the failure usually looks like a slider with a stock photo and a line such as “Excellence in Every Detail”. That says nothing. Compare it with “Modular kitchens and wardrobes for flats in Navi Mumbai, designed and fitted in 45 days”. The second tells me what you sell, where, and why you are different, before I scroll.

A simple test for your headline: if a competitor could paste it onto their site unchanged, it is not doing its job.

4. There is no clear next step

A visitor who is interested still needs to be told what to do. Many sites end a page with nothing, or with five equal options (call, email, form, WhatsApp, visit) that make the choice harder. In my experience, small-business sites do best with one primary action per page, shown as a clear button, and one quieter alternative.

• Service businesses (clinics, salons, repairs): “Book a slot” or “Call now” as the main button.
• Higher-value or considered purchases (interiors, B2B supplies, real estate): “Get a quote” or “Ask on WhatsApp”, with what you need from them spelled out.
• Retail and e-commerce: “Add to cart” should never be below the fold on a product page.

Wording matters more than colour. “Submit” tells the visitor nothing. “Get my quote by tomorrow” tells them what happens next and when.

5. It is hard to contact you

This sounds too basic to list, yet it is the most common fix I make. The phone number is an image, so it cannot be tapped. The WhatsApp button opens a number that nobody monitors. The address is in the footer, without a map link. The form asks for twelve fields, including “company turnover”, to send a simple question.

Forms also fail in ways owners cannot see. WebAIM’s scan found 51% of home pages had form inputs without proper labels in 2026, which makes them hard to use with screen readers and, on phones, often means the placeholder text disappears as soon as someone starts typing and they forget what the field was for. Then there is the silent failure: a form that looks fine but never delivers the email.

6. The text is hard to read and the site is hard to use

Accessibility is usually discussed as a compliance topic. For a small business, it is mostly about whether people can read your page in a moving local train, on a cheap phone, in bright light. WebAIM’s 2026 Million report, which tests the home pages of the top one million websites, found detectable accessibility failures on 95.9% of them, averaging 56.1 errors per page.

Low contrast is the one I would fix first, because it affects everyone, not only people using assistive technology. Pale grey body text on white, or white text over a busy photo, is common in templates because it looks elegant in a designer’s mock-up on a large monitor.

7. It looks out of date, and visitors judge you for it

People do judge a business by its website’s appearance. In a Stanford study reported by Consumer WebWatch, 2,684 people evaluated the credibility of live websites, and the site’s “design look” was mentioned most often, in 46.1% of comments. That study dates from 2002, so the specific figure is a historical one, but the underlying behaviour is easy to recognise in yourself.

What reads as “outdated” today is less about fashion and more about neglect: a copyright year from 2019, a “latest news” section whose latest item is three years old, broken images, offers that have expired, and photos of a team that has changed. Those details tell a visitor nobody is minding the shop.

8. The content is about you, not the customer’s question

Many small-business sites open with the founder’s story, the year of establishment and a mission statement. Visitors arrive with a question: can you do this job, in my area, at a price I can handle, and how soon? If your pages do not answer that, they go back to Google and try the next result.

Four things I check on every service page: Is the service described in the words a customer would use, not trade jargon? Is the service area named (Kharghar, Panvel, Thane), not just “Mumbai”? Is there at least a price range or an explanation of what drives the price? Are the common questions answered on the page?

9. There is no proof that you are good at it

Claims are cheap. “Best quality, timely delivery, 100% satisfaction” appears on thousands of sites and convinces nobody. Proof is specific: a real photo of a finished job with the locality named, a review with the customer’s name, a number of projects completed, a certification with its number, a client logo used with permission.

For local businesses, your Google reviews are the most credible proof you have, because the visitor knows you did not write them. Linking to your Google Business Profile, or showing a few recent reviews with a link to the full list, works better than a carousel of anonymous quotes.

10. It is not secure, or parts of it are broken

Most sites have HTTPS now, but I still find older sites without it, or with it expired. Chrome began marking HTTP pages “not secure” in 2018, and from Chrome 70 (October 2018) it shows a red “not secure” warning when someone types into a form on an HTTP page, according to the Chromium blog. That warning appears exactly when a visitor is about to enquire.

On rankings, keep expectations modest. When Google introduced HTTPS as a ranking signal in 2014, it called it “a very lightweight signal”, affecting fewer than 1% of global queries and weighing less than content quality. The bigger reason to fix it is the warning, not the ranking.

The wider problem is broken things nobody notices: links to pages that no longer exist, a “download brochure” button pointing at a deleted PDF, a payment link that has expired, a Google Map embed showing your old address.

Where this advice breaks down

I want to be clear about the limits of a list like this, because it can push owners into spending on the wrong thing.

• These fixes help with conversion, not with traffic. If almost nobody visits the site, a faster form will not change much. Check your analytics or Search Console first. Under a few dozen visits a month usually means a visibility problem, which is SEO, Google Business Profile or ads work.
• Page experience does not beat relevance. Google’s own page experience guidance says Core Web Vitals are used by its ranking systems, but that Google “always seeks to show the most relevant content, even if the page experience is sub-par.” A fast page that does not answer the search will not rank because it is fast.
• Some of the data is old or from other markets. The Stanford credibility study is from 2002, the dwell-time data from 2010, and the Deloitte speed study covers large European and US brands. I use them for direction, not as forecasts of what your business will gain.
• Your offer might be the real problem. If your prices, service area or reviews are weaker than the three competitors next to you in search results, no website fix closes that gap.
• Do not rebuild because of one leak. Most of the ten fixes above are edits to an existing site. A full redesign is worth it only when several problems share one root cause, such as a theme that cannot be made fast.

How I would audit your site in one afternoon

1. Open the site on a mid-range Android phone over mobile data, not Wi-Fi. Note how long the home page takes to show its main content.
2. Run the home page and top service page through PageSpeed Insights and note the real-user Core Web Vitals.
3. Ask someone outside the business what you do, after ten seconds on the home page.
4. Try to contact yourself three ways: tap the phone number, tap WhatsApp, fill in the form. Confirm each one reaches a person.
5. Read every page outdoors at full brightness and note text you cannot read easily.
6. Click every button and link once, and look for anything dated.
7. Compare your service page side by side with the top three competitors in Google for your main search. Note what they answer that you do not.

Checklist: the ten mistakes in one place

Most of these take an hour, not a rebuild. In a case like the interior designer’s at the start, the fix is one afternoon spent on a cookie banner, not a new website.
