Are you aware of the 18 top key features of website design? Explore essential features of a website design that you might be missing.
Eighteen features, one list, every item weighted the same. That is the lie built into this format, and I have written enough lists like it to own the criticism.
So here is what I actually think, from a studio in Kolkata that builds these for a living. Three items below decide whether a website works: what it says that nobody else could say, whether it stays fast and stable on a mid-range phone, and whether it tells a visitor what to do next. The other fifteen are hygiene. Hygiene is not optional, and a site with no SSL certificate or a broken contact page is a broken site. But nobody has ever chosen a supplier because the footer had a sitemap in it.
[IMG: Three features decide whether a website works: saying something no competitor could say, staying fast and stable on a mid-range phone, and telling a visitor what to do next. The other fifteen, from brand logo to site search, are hygiene: not optional, but not why anyone chose a supplier.]
Read the list as a checklist for the fifteen and an argument for the three. Every number below was checked against a primary source on 31 July 2026, and where the standard claim has no source behind it, I say so instead of repeating it.
Your brand name and logo are the first things visitors should notice when they arrive on your website. They are key to establishing brand recognition and trust. Your brand name should be prominently displayed on your home or landing page—ideally at the top, in the middle, or left corner—so it’s immediately visible without scrolling.
Your domain is how people find you and how they repeat you to somebody else. A free subdomain with the host’s name in it announces that the business has not committed to itself yet.
Navigation is the map. If a visitor cannot see where the thing they came for lives, they leave, and no amount of design elsewhere compensates.
A responsive design automatically adjusts your website’s layout based on the device being used, whether it’s a desktop, tablet, or smartphone. With more people accessing websites on mobile devices, responsive design is crucial for providing a seamless user experience.
One thing this list left out entirely, and should not have. Responsive is not the same as accessible, and accessibility stopped being a nice-to-have. WCAG 2.2 has been a W3C Recommendation since 5 October 2023, republished on 12 December 2024 with errata and not a single success criterion added or renumbered — so if a proposal quotes you only the 2024 date, it is describing a standard that is nearly three years old, not a fresh one. The European Accessibility Act has applied since 28 June 2025, which reaches Indian businesses selling into the EU whether or not they have noticed. The mechanics are in our guide to website accessibility compliance, and the layout side is in the responsive web design guide.
Speed drives bounces and feeds ranking, and it has published thresholds now instead of folklore. You will read everywhere that research shows users expect a site to load in under 3 seconds. I went looking for that research and could not find it, so I do not quote it.
What does exist is Google’s Core Web Vitals, and the numbers are specific. Largest Contentful Paint should occur within 2.5 seconds. Interaction to Next Paint should be 200 milliseconds or less. Cumulative Layout Shift should be 0.1 or less. Each is measured at the 75th percentile of page loads, segmented across mobile and desktop. If your checklist still lists First Input Delay, throw it out. INP replaced FID as a Core Web Vital on 12 March 2024, and FID is gone.
[IMG: The three published Core Web Vitals thresholds: Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint at 200 milliseconds or less, Cumulative Layout Shift at 0.1 or less, each measured at the 75th percentile of real page loads. First Input Delay is gone.]
Two things follow from that which nobody selling you a website will volunteer. Those thresholds are measured on real visitors, so a fast score on studio wi-fi proves nothing about a customer on a mid-range Android on a bad connection. And Lighthouse, the tool most agencies screenshot for you, bands its performance score 0 to 49 as poor, 50 to 89 as needs improvement, and 90 to 100 as good. Chrome’s own documentation says reaching 100 is “extremely challenging to achieve and not expected”. If someone has promised you a perfect score, they have promised you something Google does not ask for.
Optimising content, structure and technical elements is what makes a site findable. The full version is in our SEO checklist; these are the parts that belong in a build.
A CTA tells a visitor what to do next: buy, book, subscribe, call. This is one of the three that decide the outcome, and the common failure is not a weak button. It is four competing CTAs on one screen, so none of them reads as the obvious next step.
Content is the backbone of your website, and readability is part of quality rather than a separate job: clear hierarchy, short paragraphs, headings that say what the section contains.
A visitor who wants to contact you and cannot is the most expensive failure on this list, because they had already decided. Make the route obvious and make sure somebody answers it.
An SSL certificate encrypts the data exchanged between a user’s browser and your website, providing a secure connection. This is especially important for websites that handle sensitive information, such as personal data or payment details, and it costs nothing for a standard site.
Live chat provides immediate assistance to visitors, which can enhance their experience and increase conversions. It’s particularly useful for e-commerce sites, where users may have questions about products or shipping.
Yes, and specificity is what makes them work. A named client with a result attached is evidence. An unattributed line of praise is decoration.
Analytics tools like Google Analytics provide valuable insights into user behavior, helping you understand what’s working and what needs improvement. This data can guide your content strategy, marketing efforts, and overall website optimization. One caution from having sat through a lot of monthly reports: the metric people argue about hardest is usually the one they have the wrong definition of.
Your About Us page is where you tell your story and name the people doing the work. Treat it as a sales page, because for anybody comparing three suppliers it already is one.
The footer holds what is not worth a menu slot: policies, contact details, a route to the rest of the site. Get it right and nobody notices, which is the correct outcome.
A blog earns traffic only if it says something a competitor could not have written. That is the whole test, and most business blogs fail it.
[IMG: FAQ section feature in website]
A well-organised FAQ section answers common questions, which reduces the number of people who have to email you to get started. One correction worth making, because a lot of advice on this has not caught up. FAQ sections used to earn an expanded rich result in Google. That ended: Google deprecated FAQ rich results on 7 May 2026 and they no longer appear in search. FAQPage markup is still valid schema and does no harm, so leave it on. But write the FAQ because a reader has the question, not because it used to win you extra pixels on a results page.
A search bar helps visitors find things without navigating for them. It is repeated everywhere that studies show users who search are more likely to convert. I looked for a study I could name and did not find one, so that is not a claim I will make. What I will say as a recommendation rather than a finding: read your site search log. It is a list of things people expected to find on your site and did not, which makes it the cheapest customer research available to you.
Work through the fifteen hygiene items and you will have a website that does not embarrass you. That is a real achievement and most sites do not clear it. But it is not the same as a website that earns anything, and I would rather you knew the difference before you spent money. If the list above reads as a catalogue of things your current site fails, the question has stopped being which features to add and become whether to rebuild, which is a different decision with its own warning signs.
The three that decide the outcome are the ones a checklist cannot help you with. What you say that no competitor could say. Whether it holds up on a mid-range phone on a bad connection. Whether a visitor knows what to do next. None of those is a feature you switch on; each is a decision somebody has to make about your specific business, which is also the argument in template versus custom web design and the reason it matters who makes it.
We run Pixel Street from Salt Lake, Kolkata, and design and build for brands including Coca-Cola, ITC and Marico. If you want the three decided properly rather than the eighteen ticked off, that is what a web development company in Kolkata is actually for.
