How Brands Can Use Smart Search AI for Better Business Outcomes

Having a business website is the bare minimum for any modern brand. It’s where almost every buyer’s journey begins. 

Once someone lands on your site, they expect accessibility. A user should be able to quickly find and consume the content they need, whether it’s your company’s mission statement on the About page or specific product information deep within the archives of an eCommerce site. Fostering the end user’s ability to find what they need is critical to keeping them engaged and pushing them toward conversion.

That’s where WP Engine’s Smart Search AI plugin comes into play. It’s the modern search solution built specifically for WordPress®¹, helping site owners, brands, agencies, and businesses deliver better, more relevant on-site search results.

Read on to learn why WordPress’ inherent search capabilities aren’t enough to meet the needs of modern users, how Smart Search AI is revolutionizing on-site search for WordPress websites, and how this simple-to-set-up, fully integrated tool can improve performance and engagement for a wide range of business and site types.

What is site search?

Site search is a specialized search engine built directly into a specific website that allows visitors to scan only that site’s content. Unlike broad web search engines like Google that index the entire internet, site search only returns results from your domain. 

Site search that returns fast, accurate results is essential. When visitors can’t find what they’re looking for, they’ll quickly move on to a competitor that can deliver. In fact, average user time on a website is just 15 seconds, so ensuring your site meets the growing expectation for fast, intelligent, personalized on-site experiences fosters better performance and engagement metrics and positions your site as a reliable source for relevant information.

Why traditional WordPress search isn’t enough

WordPress has long been the low-cost, user-friendly CMS chosen by the majority of site owners and developers on the web. Unfortunately, its native search functionality has not seen much improvement over the years.

While WordPress is ideal for posting and publishing content, its built-in search has some glaring limitations. By default, WordPress search:

• Only covers exact keyword matching between a user’s input and the results it returns, meaning a simple spelling error from your user is enough to eliminate the most relevant results for their query.
• Has no semantic understanding or natural language capabilities, so it won’t understand that “down parka” is an acceptable result when someone searches “winter coat.”
• Lacks personalization and real-time relevance, prioritizing older, more established posts over current, more relevant information.
• Lacks in-depth search insights to help you make informed decisions for your site.
• Does not recognize variations of words. For example, if a user inputs “run,” WordPress’ inherent search would not return results for “running” or “ran.”
• Can be slow to return results on sites with a high content volume.

To put it simply, WordPress’ inherent search functionality doesn’t understand language or seek content the way humans do. 

Improving the search results your site serves to users requires more than WordPress can provide out of the box. But this begs the question: Does it make business sense to invest time and money into your website’s search experience?

Business impact: Why search matters for conversions and revenue

43% of website visitors who arrive on a site with a specific intention in mind will head straight to its search bar, according to Coveo’s 2025 CX Relevance Report.

Additionally, 53% cited “not being able to easily search for and find the information I’m looking for on my own” as the biggest problem they have with self-serving on a site.

Both marketers and consumers see companies as having significant room to improve the consistency of customer experiences related to personalizing recommendations based on user behavior, according to a study conducted by Harris Poll.

So, it stands to reason that improving the relevance of search results across your website is one of the easiest ways to improve the overall consistency and quality of your customers’ experiences—not to mention your site’s conversions.

Basic vs. advanced website search performance tools

As you evaluate search tools for your WordPress site, it’s important to decide what capabilities you need. Some website search performance tools provide only basic improvements to your on-site search, while more advanced tools can drastically improve experiences for your users.

Feature	Basic site search tool	Advanced site search tool
Matching style	Exact match: User queries are only matched to results that perfectly match	Semantic and intent-aware retrieval: Comprehends the underlying meaning, natural language queries, and synonyms
Error tolerance	Zero tolerance: Typos, misspellings, and character errors will return no results	High tolerance: Auto-corrects typos and interprets vague phrases to serve up the correct results anyway
Result delivery	Static: Results display in chronological order, not based on what the user actually wants	Personalized recommendations: Uses machine learning to suggest relevant, trending, or related items tailored to user behavior
Performance and scalability	Server-heavy: Each query directly taxes your core database, slowing down page load times	Offloaded processing: Search queries are handled on specialized external servers, ensuring fast results

The simple solution: Smart Search AI with AI-Powered Recommendations

WP Engine’s Smart Search AI with AI-Powered Recommendations goes beyond traditional search by incorporating semantic search and machine learning, allowing your website to better understand and interpret user queries and deliver results that truly align with user intent.
