We’ve also added insights on how modern tools and technologies can enhance search functionality, making it faster, smarter, and more user-friendly.
Should your website have a search bar? If your platform is content-heavy or ecommerce-driven, the answer is almost always yes. A well-designed search bar isn’t just a convenience — it’s a critical navigation tool that helps users find what they need quickly, reducing frustration and improving engagement. Especially in large catalogs or information-dense sites, users often rely on search to bypass complex menus and get straight to their goal.
In this article, I will explore the main considerations for designing an effective search bar with autocomplete. I’ll dive into usability principles, design choices, and common pitfalls to avoid. I’ll also share a list of tools and services to help you create a search bar that works it all out for your users.
Before you start designing any UI component for your website, step back and take into consideration how some basic best practices and principles of UX design can apply to search bars:
Not all searches are created equal. Users approach search bars with different goals, and understanding these intents is key to designing an effective search experience.
Generally, search behavior falls into three categories:
| Search Type | Common Use Cases | Example | UX Implications | Example User Journey |
|---|---|---|---|---|
| Navigational search | SaaS platforms, enterprise dashboards | A Notion user searching for “My Templates” to access saved layouts | Ensure quick, direct access to known locations |
|
| Transactional search | Ecommerce platforms | A user on ASOS searching for “men’s winter boots” with purchase intent | Provide high-relevance results, strong filtering, and clear CTAs |
|
| Informational search | Help centers, blogs, educational platforms | A Figma user searching “how to create a component” in the help docs | Ensure well-structured content, clear search snippets, and scannable results |
|
Jakob’s Law states that users prefer websites that are similar to others they have used in the past. In the case of search bar UX, that means the user expects to find the search bar placed in the same location that they find it on most other websites — at the top of a website, and both clear and easy to identify. Here’s what I mean:
Ensure that the search bar integrates with the overall UI and maintains consistency in placement, typography, and interactions.
Bolding search terms in autocomplete results, for example, allows users to quickly scan through relevant matches.
Users prefer interfaces that are easy to understand and won’t demand cognitive effort, so use labels, icons, minimalism, and intuitive UI design in your search bar.
A great example of that would be Figma’s search bar. It doesn’t have an overwhelming design and provides an icon, so the user can quickly skim through the page and find it.
Additionally, a placeholder text provides a clue about what can be searched. Spotify does this exceptionally well with the placeholder text — “What do you want to play?”:
Your search algorithm should be able to understand the user’s intent and return the most relevant results. It should also be able to handle misspellings, synonyms, and other variations in the user’s search query.
To accomplish this, your developer team might use a combination of:
And, yes, we also have APIs that can do a good job — we will talk more about them later.
User feedback, too, can help you refine the search UI. Consider adding a small feedback mechanism (e.g., “Was this search result helpful?”) to continuously improve the search experience.
The search function should be fast and responsive. This means that it should return results quickly without making the user wait, and it should be able to handle large volumes of data without slowing down your page.
The specific amount of time that is considered acceptable will depend on the context and the user’s expectations, but users don’t want to wait. If you can, keep it below two seconds.
According to a study by Portent, a slow website will directly affect your conversions. So fast search results are super critical.
The search function should allow users to customize and refine their search results. This means that it should provide users with options to filter or sort their results, as well as to save and access their previous search queries and results.
Let’s look at LinkedIn:
LinkedIn shows a list of trending searches based on what other users are looking for, such as popular job titles, skills, or companies.
Why it works — Trending searches encourage users to explore popular topics and help them discover opportunities they might not have considered. It also keeps the search experience dynamic and relevant to current trends.
Per Jakob’s Law, your search bar needs to be familiar enough for new users to navigate. A good search bar includes:
Imagine that your website was actually a physical space, and your user arrives at this space looking for something. Would that person need help?
A well-designed information architecture on a website helps users to find the content they’re searching for. However, if they’re in a hurry or need a little extra guidance to find something, a search bar can ease friction and enhance UX.
In general, a search bar is a valuable addition to any website that has a large amount of information or content:
In these cases, a search bar can help users easily find the information they’re looking for and make their experience on the website more efficient.
However, for websites with simple navigation and a small amount of content, it may be worth testing and verifying whether a search bar is truly necessary. For example, you may not need a search bar for sites like:
Overall, the decision to include a search bar on a website should be based on its specific needs and goals and the amount and complexity it contains.
Search has come a long way from just typing in keywords and hoping for the best. Today’s search experiences are smarter, faster, and more intuitive. Here are some modern trends that are changing how users find what they need:
With voice assistants like Siri, Google Assistant, and Alexa, more people are searching hands-free. Adding voice search to a website can make things easier, especially for mobile users or those who prefer talking over typing
Think of how Google’s search bar has a little microphone icon — tap it, say what you’re looking for, and get results without lifting a finger.
Instead of forcing users to type rigid keywords, modern search tools understand conversational language. That means users can search the way they naturally talk.
For example, instead of typing “laptop 16GB RAM under $1000,” someone might say, “I need a laptop with 16GB of RAM for less than $1000,” and still get relevant results.
Ever seen something cool but didn’t know what to call it? Search by image lets users upload a picture to find similar products, places, or even information.
Google Lens, for example, lets you snap a picture of a product, and it’ll find similar ones online. Shopping apps like Amazon and ASOS also let users upload images to find matching or related items.
Search is getting better at reading minds (well, almost). Autocomplete suggests search terms as users type, while predictive search offers results before they even finish their query.
Netflix doesn’t just autocomplete searches — it suggests movies or shows based on what you’ve watched before.
Search results are now tailored to individual users based on their history, preferences, and behavior.
Spotify, for example, personalizes search results by pushing your favorite genres, artists, and frequently played songs to the top.
Amazon’s search bar is large and prominent and supports autocomplete suggestions based on past searches, trending items, and categories:
