The five most common causes, how to tell which one is yours, and the order to fix them. “My site is slow” isn’t a diagnosis on its own, and any fix applied before you know where the slowness lives is guesswork. The good news: this is measurable, and measuring it is free. ## Measure first, touch second PageSpeed Insights takes your address and shows two different things: a lab test and real user data. The second matters more — that’s what your actual visitors experience. Three values to read: - **LCP** — how long the main content takes to appear. Most of the “it feels slow” sensation lives here. - **CLS** — content jumping around while the page loads. Not slowness, but just as irritating. - **INP** — how long the site takes to respond when you tap something. Optimising without knowing which of these is bad is giving the right medicine for the wrong illness. ## The five most common causes **1. Uncompressed images.** The most common cause and the easiest fix. A photo taken on a phone and uploaded directly can be several megabytes; the same image as WebP at the right dimensions can shrink by ninety per cent. **2. Plugin accumulation.** Every plugin loads its own CSS and JavaScript on every page — even pages that don’t use it. Plugins that piled up over the years and are no longer used quietly add weight. **3. No caching.** Without a cache, the page is built from scratch for every visitor. A properly configured cache layer is a big win on most WordPress sites, but it hides root causes such as server or plugin load, so I set it up after fixing those. **4. The server.** On cheap shared hosting, the server’s first response can take seconds by itself. In that case the ceiling stays low no matter what you do on the site side. **5. Page builder markup.** Elementor and similar tools give you flexibility, but the nested box structure they produce gives the browser extra work. Not a disaster on its own — but combined with the other four, the total gets heavy. ## The right order Take these in sequence rather than at random, or you’ll never know which one helped: 1. Images — biggest win, lowest risk 2. Server and database assessment — this sets the ceiling for the first response time 3. Removing unused plugins 4. Caching — after the root causes are fixed; otherwise it hides the problem and muddies later measurements 5. Template or theme level work (and CDN) — the riskiest, so last Measure again after each step. Change five things at once and you’ll never know which one worked. **Want me to measure it?** I can identify which item is slowing your site and give you an order of priority; the work itself is [WordPress speed optimisation](https://oguzerol.com/en/wordpress-speed-optimization/).

Speed separates two pages of equal quality; it won’t rescue weak content. Its real effect is reducing the number of visitors who give up and leave. ### Is installing a speed plugin enough? Usually not, and sometimes it hurts. Two plugins doing the same job can break each other. A caching plugin is necessary but not sufficient. ### Is e-commerce different? Yes — cart and account pages can’t be cached, so the setup is more involved. [WooCommerce speed optimisation](https://oguzerol.com/en/wordpress-speed-optimization/) covers that separately. ### My site is slower on mobile, is that normal? Some difference is expected, but a wide gap means there’s a problem. Mobile processors are weaker, so JavaScript weight is punished harder there.

Work-hour packages Tell me about your business and what you need on WhatsApp or by phone; we agree on **a work block of somewhere between 5 and 40 hours** and I start doing what is needed. What you get is not a calendar window — it is net working hours spent directly on your business. I can use 40 hours working three days straight, or deliberately spread it out and finish it over a year — whatever the work calls for. I do not spend my time estimating how long something will take, I spend it doing the work; every hour I spend leaves a lasting result in your business. We keep going for as long as you find it useful. WORK BLOCKS ## Why not monthly? Is 40 hours a week? On a fixed monthly fee both sides are watching the wrong thing: you watch a fixed cost, the other side watches how many more contracts like this they can line up. Working by the hour puts us both in front of the same thing — the real value of the work that got done. I know not having an upfront answer to "how much will this cost in total?" is the natural cost of this model. But instead of paying a fixed fee for months to a setup that is not producing results, you only pay for the qualified time spent on your work — and you see exactly where that time went, start to finish. That is why my clients keep coming back. 5hours300€ + VAT60€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%205-hour%20work%20block.) 10hours500€ + VAT50€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2010-hour%20work%20block.) 20hours800€ + VAT40€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2020-hour%20work%20block.) 40hours1,400€ + VAT35€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2040-hour%20work%20block.)
