How to Identify Page Elements Slowing Down Your Business Website

Start with a performance baseline

Before you can fix what is slow, you need to know what the speed actually is. Run a test on your live site using a tool like Google PageSpeed Insights, GTmetrix, or WebPageTest. These give you a score and a breakdown of what is hurting it. Pay attention to the Core Web Vitals metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). A poor LCP often points to a hero image or a large video file loading above the fold. A high CLS might mean a script is pushing content around after the page has already started rendering. Run tests from a few different locations and on both desktop and mobile. The mobile view is especially telling because connection speeds and screen constraints exaggerate problems that a desktop might hide.

Look at the weight of your images and media

Images are the most common drag on a landing page. Uncompressed photos, high-resolution graphics used as thumbnails, and background images that are not optimised for the web all add weight. A single 2 MB image can double your page load time on a 4G connection. Check every image file on the page. If the file size is above 200 KB for a decorative element, it is worth compressing it or switching to a next-gen format like WebP. Video files are even heavier. Autoplaying background videos or large hero clips that do not use adaptive streaming will stall the page. For video, consider serving a lightweight poster image first and loading the real player only when the user taps play. Also check if you are loading video from a third-party embed that pulls in extra scripts and tracking pixels.

Audit your third-party scripts and embeds

A typical business website loads analytics trackers, chat widgets, social media feeds, remarketing pixels, and font services. Each one adds a network request and often a blocking script. Open your page in a browser and use a tool like Chrome DevTools to list all the external requests. Group them by domain. You will often find that a single embedded map or a chatbot is making five or six separate calls. Scripts that load in the and block rendering are the worst offenders. For each script, ask whether it truly needs to load on every page. If it only makes sense on a contact page, move it there. For the ones that must stay, load them asynchronously or defer them until after the main content is visible. A common mistake is loading a font service that fetches three weights of a typeface when only one is used. That alone can add a full second to load time.

Check your server response time and hosting

Sometimes the bottleneck is not on the page at all. A slow Time to First Byte (TTFB) means the server is taking too long to return the HTML. Run a test and look at the TTFB. If it is above 300 milliseconds, the hosting setup may be the issue. Shared hosting plans often put dozens of sites on one server. If your neighbour has a traffic spike, your site slows down along with theirs. Moving to a VPS or a dedicated server gives you more predictable performance. A Content Delivery Network (CDN) also helps by caching static assets closer to the visitor. If your site runs on a CMS like WordPress, check your plugin count. Each plugin adds database queries and PHP execution time. A site with fifty plugins will likely have a slow TTFB even on fast hardware. Strip out any plugin that duplicates functionality or that you installed for a one-time task.

Examine your CSS and JavaScript payload

Clean code is lean code. Many sites load a full CSS framework like Bootstrap or Tailwind and then use only a small fraction of the classes. The same happens with JavaScript libraries. A page might load jQuery, a slider script, and a modal library when the page only needs a simple menu toggle. Use a tool to audit the rendered page size. If the total CSS and JS files exceed 500 KB before compression, you have room to slim down. Look for unused CSS rules and remove them. For JavaScript, consider using a build tool that bundles only the functions your page actually calls. Another common problem is loading scripts in the that should be at the bottom of the body. Scripts in the head block the rendering of everything below them. Move them to the end of the body unless they are absolutely critical. For modern browsers, the 'defer' and 'async' attributes let you load scripts without blocking the page build.

Watch for render-blocking resources

Even after you have moved scripts, some resources still block the render. A large hero image loaded with a fixed height and width can cause the browser to pause until it has the dimensions. Similarly, a web font that is loaded with a 'font-display: swap' rule will cause a flash of invisible text while the font downloads. The fix is to use 'font-display: optional' or to preload the font file in the with a link tag. Another hidden blocker is inline CSS embedded in the HTML that references external images or fonts. The browser cannot finish rendering until those external items are fetched. Check your page with the 'blocking' filter in DevTools. Every resource that appears in the list is a candidate for deferral, inlining, or removal.

Assess your mobile experience separately

Responsive design is about more than fitting the screen width. On mobile, the connection is often slower and the processor is weaker. A page that loads in two seconds on desktop might take six seconds on a 4G connection. Use the mobile test results from PageSpeed Insights to see the specific issues. Often, a mobile view will show that images are still being served at desktop resolution and then scaled down by CSS. That wastes bandwidth. Serve different image sizes for different viewports using the srcset attribute. Also check that touch targets are large enough. Small buttons and links force the user to zoom, which reloads the viewport and adds friction. Good responsive design considers both layout and performance.

The conversion funnel depends on every page performing smoothly. A landing page that loads slowly loses visitors before they ever see the offer. At Animation & Whatnot, we see that trimming the fat from a page's code and assets can lift conversion rates noticeably. The effort is not about chasing a perfect score in a testing tool. It is about removing the elements that make a visitor wait. Each second of delay reduces the likelihood of a click, a signup, or a sale.

Check your hosting environment's cache settings

Server-side caching can reduce load times dramatically, but only if it is configured correctly. Check whether your server sends Cache-Control headers for static assets like images, CSS, and JavaScript. Without them, the browser requests the same files on every visit. Ideally, images and scripts should have a cache duration of at least a week, and versioned files can be cached for a year. On the server side, enable page caching for anonymous users. A cached HTML page can be served in a few milliseconds instead of running PHP or database queries. If your site uses a CMS, install a caching plugin or enable the built-in cache. Also check whether your CDN is actually being used. Sometimes developers set up a CDN but do not point the DNS records to it, so all traffic goes to the origin server anyway.

Review your database queries and server-side logic

For dynamic sites, the database is often the hidden bottleneck. Every page request that runs a query takes time. If your site shows a list of recent blog posts, a product grid, or user-specific content, the query should be optimised. Use a slow-query log on your database server to find queries that take more than a second. Common fixes include adding indexes, limiting the number of returned rows, and avoiding queries inside loops. For example, a loop that runs a separate query for each product in a list of twenty products will create twenty round trips. Replace that with a single query that fetches all the data at once with a JOIN. For high-traffic pages, consider caching the query results in memory with a tool like Redis or Memcached. The server then serves the cached data instantly instead of hitting the database on every request.

At Animation & Whatnot, the balance between visual impact and speed is a constant consideration. A high performance web design does not mean stripping away everything that makes a site interesting. It means knowing exactly where the weight comes from and making intentional choices. With a methodical audit, you can identify the page elements that are slowing down your business website and address them one by one. The result is a site that loads fast, works well on every device, and gives visitors a reason to stay.
