Site search used to be a box that matched keywords to page titles. Buyers now look at a different category: tools that read a website’s own content and answer a visitor’s question directly, with a link to the source page. The category is growing quickly, the demos all look polished, and it is easy to buy a tool that cannot be trusted on your actual documentation.
If you are comparing options for a help centre, a documentation site or a content-heavy marketing site, you need a buying process that tests the answers, the sources, the install, and the analytics, not only the interface.
This is a practical way to evaluate AI site search before you sign a contract.
Start With the Job, Not the Model
Write down what you want the search to do for a visitor and for your team. A typical pair of jobs looks like this:
- For the visitor: ask a question in ordinary language and get a short, accurate answer taken from our published pages, with a link to the source.
- For the team: see what people asked, what was answered, and which questions the site failed to handle.
Notice what is not in that list: an open-ended chatbot, a tool that answers from the public internet, or a replacement for your knowledge base. AI site search should sit on top of content you already maintain. It should not invent policy or browse the web for a better-sounding paragraph.
If your main problem is “people cannot find the article that already exists,” you are in the right category. Independent research on site search quality has shown for years how often on-site search fails to match what people type with the page that would have helped them; AI site search is a newer way to close that gap, but only if you test it on your own content. If your main problem is “we do not have the article,” search will not fix that, although query logs will show you what to write. Self-service only works when the underlying content is there, a point that also comes through in guides to self-service knowledge base software.
The Test That Matters: Your Questions, Your Pages
Ask every vendor for a trial on your site, or on a copy of your public docs. Then run a fixed test.
- Collect 20 real questions. Pull them from support tickets, current search logs, sales FAQs and the questions your team hears on calls. Include easy ones and awkward ones.
- Run them through your current search. Record whether the first result was useful. This is your baseline.
- Run the same 20 through the trial. For each question, record whether the answer was correct, partly correct, or wrong, and whether the cited page actually supports the answer.
- Include traps. Ask about a policy you do not have, a feature you retired, and a topic you cover only in an old blog post. You want to see refusals and citations, not improvisation.
- Edit one article during the trial and ask a related question the next day. If the answer is stale, the index will be a problem in production.
Score the tool on accuracy, citation quality and stale-content behaviour. A slightly less fluent answer that points to the right page is more useful than a fluent answer with no source, or a source that does not say what the answer claims.
Questions to Ask Every Vendor
The demo will show a happy path. Your checklist should cover the paths that fail.
Where do the answers come from?
The only acceptable default for site search is the site’s own published content. Ask whether the tool can be limited to selected collections (docs, not the blog, or vice versa), and whether it will ever fill a gap from a language model with no source.
How are sources shown?
Visitors should be able to click through to the page the answer came from. If citations are optional, buried, or point to a homepage rather than a section, treat that as a defect.
How does indexing work?
Ask how new and edited pages get into the index, how long that takes, and whether passworded or staging pages can be excluded. A weekly crawl is not enough for a knowledge base that changes with each release.
What does installation require?
A lightweight snippet on WordPress, Webflow or a custom site is very different from a project that needs a developer for a week. Confirm what happens with single-page apps, and whether you can style the widget to match the site.
What do the analytics include?
You want queries, answer rate, and unanswered or poorly answered questions. Click-through to cited pages is a bonus. Vanity counts of “AI responses served” are not a buying criterion.
What is the failure behaviour?
When the tool is not sure, it should say so and offer keyword results or a contact path. A confident wrong answer is worse than “I could not find that.”
Price, Scope and the Contract
Price the tool against the cost of tickets it might deflect and the time your team spends hunting for the right article, not against the cheapest chatbot you have seen. Check page limits, question or answer limits, and what happens if you exceed them. Confirm that your content is not used to train a general model if that matters to you, and how you export or delete data if you leave.
Start with a trial that includes your real content. A proof of concept on a vendor’s sample site will not show how the tool handles your headings, your older posts, or your policy language.
A Tool to Include in the Comparison
One option in this category is AI-powered site search from Qurify. It indexes the pages you publish, answers questions in natural language with citations to the source pages, and re-indexes as the site changes. It is designed to install with a snippet on common CMS platforms, and the analytics highlight queries, answers and content gaps. Plans start with a 14-day trial, which is a reasonable window for the 20-question test above.
Use the same test for every vendor, including this one. The right purchase is the tool that answers your actual questions from your actual pages, and shows you where it cannot.
The Bottom Line
Buying AI site search is not about picking the most impressive demo. It is about whether the product will tell the truth on your site. Define the job, run a fixed set of real questions, insist on citations, check how the index stays current, and look at the questions the tool cannot answer. That process takes a couple of weeks and will prevent a much more expensive mistake later.
