A slow website is an expensive website.

Why is my website lagging?

A website lags when the browser has to download, parse and run more than the visitor's device and connection can handle before the page is usable. The usual causes are uncompressed images, too many third-party scripts such as chat widgets, trackers and fonts, heavy page builders or themes, JavaScript that blocks rendering, slow shared hosting with no caching or CDN, and a database that answers every request from scratch. Each one adds to the delay, and on a phone over a mobile connection the delays stack up. A Lighthouse or PageSpeed Insights report lists them in order, which is where GrossiWeb's performance optimization work begins.

Lag that appears only after a click, rather than on load, points to Interaction to Next Paint problems: long JavaScript tasks running on the main thread. Those are fixed in the code, not with a faster server.

How do I get my website to load faster?

Start with the fixes that remove the most weight: compress and resize images and serve them in WebP or AVIF, remove scripts you do not use, defer the rest, load fonts locally with a fallback, and put the site behind a CDN with edge caching. Then fix the code: eliminate render-blocking resources, reserve space for images and embeds so the layout does not shift, and break up long JavaScript tasks. If the site runs on a heavy theme or page builder, a rebuild is often cheaper than repeated patching. GrossiWeb's web development service builds sites in Next.js with a Core Web Vitals pass before hand-over, from $8,000 for a marketing website.

Why are websites so slow right now?

Websites feel slower today because pages have grown heavier, not because connections have got worse: larger images and video, more tracking and advertising scripts, consent banners, chat widgets, embedded feeds and JavaScript frameworks loaded in full for pages that need a fraction of them. Each addition adds weight, and mobile devices on cellular connections feel the difference first. Slowness on a particular site can also be a hosting problem, an outage at a third party the page depends on, or an unoptimised database. Measuring the page in PageSpeed Insights separates a site-wide problem from a temporary one, and GrossiWeb's performance work starts from that measurement.
