Business website mistakes are something every owner of an online business in Indonesia needs to understand. Building a business website looks easy: pick a template, fill in the content, then publish. In reality, many business owners make costly mistakes when building a website that directly affect visitors, conversions and Google rankings. This article sets out the 7 most common mistakes and how to avoid them.

Mistake #1: No clear goal
Many business owners build a website simply because “competitors have one”. Without a clear goal, whether that is generating leads, selling products or building brand awareness, your website will lack direction. Every element on the page, from design to content, should support one main, measurable goal.
Before you start a website project, answer these questions: What do visitors want to achieve on my website? What do I want to achieve from this website? How will I measure success? The answers become the foundation for every design and content decision.
Mistake #2: Slow loading and poor performance
Google research found that 53% of mobile visits are abandoned when a page takes more than 3 seconds to load, which makes a slow site one of the most damaging business website mistakes. A slow website hurts the user experience, and it also lowers your Google rankings significantly through Core Web Vitals. Common causes of slow loading: uncompressed images, low-quality hosting on weak servers, too many plugins and no CDN.
The fix: use good-quality SSD hosting, compress all images to WebP, turn on caching and minimise your CSS and JavaScript, all basic ways to avoid mistakes when building a business website. The ideal target is a First Contentful Paint (FCP) under 1.8 seconds and a Largest Contentful Paint (LCP) under 2.5 seconds.
Mistake #3: A design that is not mobile-friendly
Most business website traffic in Indonesia now comes from mobile devices, so neglecting phones is among the most expensive business website mistakes. A website that is not responsive, with text that is too small, buttons that are hard to tap and a layout that falls apart on small screens, loses most of its visitors straight away. Worse still, Google uses mobile-first indexing, which means the mobile version of your website is the one assessed for search rankings.
Use a responsive framework such as WordPress with a modern theme, test your website on a range of screen sizes and make sure CTA buttons are easy to tap with a finger (at least 44×44 pixels), because buttons that are too small are a business website mistake people often miss. Test the mobile view with Lighthouse or PageSpeed Insights.
Mistake #4: No clear call to action
Visitors who arrive on your website have already shown interest, and leaving them without direction is one of the quieter business website mistakes. If they do not know what to do next, they will leave. Common mistakes: no CTA at all, a CTA hidden at the bottom of the page, or so many options that visitors get confused (the paradox of choice).
Every page should have one clear, prominent main CTA, the simplest guard against this business website mistake. Use specific action language: “Book a Free Consultation Now”, “Get a Quote” or “Start Your 7-Day Free Trial”. The button colour should contrast with the background, and the button should be big enough to catch the eye.
Mistake #5: Thin, irrelevant content
Many business websites have only “About Us”, “Services” and “Contact” pages with generic descriptions, a classic among business website mistakes. Content like this does not answer potential customers' questions, does not help SEO and does not build trust. In 2026, Google is increasingly strict in evaluating E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness).
The fix: create content that answers your potential customers' specific questions, so you steer clear of this business website mistake. Add real testimonials with photos, case studies, relevant figures and data, and an FAQ based on the questions you commonly receive. A consistent blog sends Google a strong signal of topical authority.
Mistake #6: Ignoring SEO from the start
SEO is not something you “add later”. It has to be planned from the moment the website is built, or it becomes one of the hardest business website mistakes to undo. URL structure, heading hierarchy, page speed, schema markup and internal link architecture all affect SEO at a fundamental level. Fixing a poor SEO foundation costs far more money and time than building it properly from the start.
Mistake #7: No maintenance strategy
A website is never a finished product. It is a digital asset that needs ongoing care. WordPress that is not updated is vulnerable to security attacks. Out-of-date content lowers visitors' trust. Broken links damage SEO. Without active monitoring, small problems can grow into a crisis.
Set up a maintenance schedule: update WordPress and plugins every week, audit content every quarter, check security monthly and monitor performance with Google Analytics and Search Console. Consider a professional maintenance service if you do not have the time or technical skills.
