Tip 8 of 31: Put Important Information in the Page Itself

A visually impressive website is not automatically a readable one. When important content depends entirely on scripts rather than being delivered in reliably rendered page content, some search engines, crawlers and AI-assisted systems may miss it.

The Problem

When you open a website, your browser shows words, images and buttons. Behind the scenes, some of that information may already be included in the initial HTML, while other parts are constructed later by JavaScript running in the browser.

For a human visitor, the result may look the same. For a crawler, it can be different.

Google can render JavaScript before indexing a page, but blocked resources, errors, slow-loading scripts or content that depends on user interaction can prevent important information from appearing in the rendered HTML. Other crawlers may handle JavaScript differently.

If your main service descriptions, key answers or most important text only appear after scripts have run or a visitor has interacted with the page, there is a risk that the content will not be reliably available to every crawler.

What This Looks Like in Practice

Common examples include tab-based pages where content is only requested after a tab is clicked, text that loads after an animation completes, key information inside client-side JavaScript components and answers that do not appear until someone opens an accordion.

None of these are automatically wrong from a design perspective.

Content that is already present in the HTML or rendered page but initially hidden visually can generally be processed by Google. The greater risk is content that is only downloaded or created after a user interaction.

Interactive content should also remain accessible to people using a keyboard or assistive technology. Important information should not depend exclusively on an interaction that some visitors may be unable to perform.

Why Getting This Right Matters

One of our clients generated £45,000 in placement fees from their website in a single month. Every page contributing to that result needed to be readable, not just visually impressive.

A beautiful page that does not make its important content reliably available in the rendered HTML may provide crawlers and automated systems with an incomplete picture of what the page covers.

What to Do

Ask your developer to check your important pages using Google Search Console's URL Inspection tool.

Use the Test Live URL feature and review the rendered HTML, loaded resources and any JavaScript errors. Confirm that the main service descriptions, key answers and other important information appear without requiring a visitor to click, scroll or complete another interaction.

For critical content, use a dependable approach such as server-side rendering, static rendering or hydration so the information is available in the rendered page. The precise implementation matters less than the result: users and permitted crawlers should be able to access the important content reliably.

Frequently Asked Questions

Does JavaScript automatically cause problems with search engine crawling?

Not automatically, but it can. Google can render JavaScript, but blocked resources, errors, slow-loading scripts or content that depends on user interaction can prevent important information from appearing in the rendered HTML. Other crawlers may handle JavaScript differently.

How can I check what a search engine actually sees on my page?

Google Search Console's URL Inspection tool includes a Test Live URL feature that lets you review how Google crawls and renders the page. Check the rendered HTML, loaded resources and JavaScript errors to confirm that the important content is available.

Should I avoid JavaScript-heavy website frameworks entirely?

Not necessarily. Many modern websites use frameworks such as React or Next.js effectively, often through server-side rendering, static rendering or hydration. The issue is not the framework itself but whether important content is delivered in a form that users and crawlers can reliably access.

Are accordion sections and tabs a problem for SEO and AI-assisted systems?

They can be, depending on how they are built. Content already present in the HTML or rendered DOM but initially hidden visually can generally be processed by Google. Content that is only requested or created after a user clicks may be less reliably available to crawlers. Interactive elements should also remain accessible to keyboard and assistive-technology users.

What is the simplest fix if important content is buried in JavaScript?

Make sure the content appears in the rendered HTML without requiring user interaction, using server-side rendering, static rendering or another dependable implementation. In some cases, restructuring the page to surface key information directly is both a crawlability improvement and a better experience for users.
