Your WordPress site takes too long to open. On your office Wi-Fi it may feel acceptable, but your visitors are not on your Wi-Fi. They are on a phone, on mobile data, sometimes in an area with a weak signal. If the page takes its time, they do not wait. They tap back and buy from someone else, and meanwhile, Google quietly pushes slow sites down the search results.
We are Raozan IT, an 8-member WordPress team based in Noapara, Raozan, Chattogram, Bangladesh. Since 2017, we have completed 800+ projects. Our WordPress speed optimization service for WooCommerce stores and WordPress sites starts with a free speed check.
Most visits now happen on mobile phones, often on mobile data. That is why we test and optimize for mobile first. No service can promise a specific score. A mobile score of 90+ on Google PageSpeed Insights is the target we work toward, but the final number also depends on your hosting, on ad networks, and on third-party scripts.
Why a slow site costs you customers
A slow site quietly loses you business. Visitors who wait too long leave before they see your products, read your services, or fill in your contact form. Online shoppers in particular will not wrestle with a sluggish checkout; they simply close the tab.
Speed also affects how you rank. Google uses Core Web Vitals as a ranking factor, so a slow site is harder to find as well as harder to use. That is why speed is part of the same work we do in our SEO services. Most sites do not become slow overnight: a bigger banner image here, a new plugin there, a chat widget, a few tracking tags, until the site feels heavy. Our guide on why your WordPress site is slow explains the common causes in plain words.
What good speed looks like: PageSpeed and Core Web Vitals
Google judges speed with three Core Web Vitals, measured on real visitors. A WordPress Core Web Vitals fix has to improve LCP, INP and CLS together.
| Metric | What it measures | Good |
|---|---|---|
| LCP (Largest Contentful Paint) | How long the main content takes to appear | 2.5 seconds or less |
| INP (Interaction to Next Paint) | How quickly the page responds to a tap or click | 200 milliseconds or less |
| CLS (Cumulative Layout Shift) | How much the page jumps while it loads | 0.1 or less |
| TTFB (Time to First Byte) | How fast the server first responds | 800 milliseconds or less |
These thresholds are judged at the 75th percentile of real visits. PageSpeed Insights scores pages in bands: 90 to 100 is good, 50 to 89 needs improvement, 0 to 49 is poor. A PageSpeed score is a lab test on a simulated phone. Passing Core Web Vitals is field data from real users over 28 days, so a good lab score does not guarantee a pass. We report both and aim for the real-visitor numbers.
What our WordPress speed optimization service includes
- Full speed audit: we test your key pages with PageSpeed Insights and check your Core Web Vitals and server response time.
- Image optimization: oversized images are a common cause of a slow LCP. We compress images, convert them to WebP, and serve each image at the size the screen needs.
- Caching setup: without a cache, WordPress rebuilds every page from scratch for every visitor. We set up page, browser, and object caching where your hosting supports it.
- Database cleanup: your database collects post revisions, expired transients, spam comments, and leftover tables from deleted plugins. We clean out that bloat, including a WordPress autoloaded options cleanup.
- Plugin audit: every plugin adds weight. We measure which plugins slow your site down, then remove the ones you do not need or replace heavy ones. Nothing is deleted without testing first.
- CDN setup: a CDN such as Cloudflare serves your static files from servers closer to your visitors. We configure it properly for WordPress.
- Font, CSS, and JavaScript optimization: we shrink code files, load the top-of-page styles first, load web fonts efficiently, and defer scripts that are not needed when the page opens.
- Honest hosting advice: sometimes the hosting itself is the bottleneck. If your server is slow to respond, no plugin can hide that. We show you the server response figures and tell you plainly if better hosting would help.
WordPress speed optimization service for WooCommerce: why stores are different
A store is harder to speed up than a brochure site, because the pages that make you money cannot be cached. The cart, checkout, and account pages must not be served from a stale cache, so the slow part is the server answering those requests. If the PHP workers are starved or the database is bloated, no caching plugin can fix that. Our WooCommerce speed optimization service works at the server and database level first: PHP and database tuning, object cache, product catalog queries, and cart fragments, then images and scripts. Then we test the full buying process, so a faster store never has a broken checkout. Our guide on WooCommerce checkout slowness explains the causes if you need to fix a slow WooCommerce checkout, and what to do when WooCommerce checkout breaks after an update. For ongoing store care, our WooCommerce maintenance plans keep the store fast month after month.
How we optimize your site, step by step
The audit and the fix are two separate pieces of work. The free speed check tells you what is slow and what each fix is worth. Nothing starts until you approve the quote.
Step 1: Free speed check and audit. You send us your site link. We test it on mobile and desktop and send a plain-language summary: what is slow, why, and what we would fix.
Step 2: Full backup. Before we change a single setting, we take a complete backup of your files and database, so we can roll back if anything misbehaves.
Step 3: The optimization work. We work through the audit findings in order: server and database first, then caching, then images, scripts, and fonts.
Step 4: Real-world testing. We retest on mobile and desktop and open your key pages in a real browser, including the checkout if you run a store, to confirm everything works exactly as before, only faster.
Step 5: Report and recommendations. You receive the before-and-after scores for your own pages, a summary of what we changed, and honest advice on what optimization alone cannot solve.
What to expect
Page builders like Elementor and Divi add extra code to every page, often 100 to 300KB of CSS and JavaScript, and that limits how far tuning alone can go. We will tell you honestly what is achievable inside it. If a heavy theme or page builder is the real ceiling, our web design services build fast from day one.
Speed helps, but it cannot replace relevant content. A fast page with thin content will not outrank a slower page that answers the question better. Speed removes a handicap, it is not a ranking shortcut. A hacked site is often a slow site, because malware eats server resources. If our audit finds signs of an infection, we will tell you, and our WordPress security services team can check that separately.
What it costs
A standard speed optimization starts from $99. The speed check and audit are free. After the audit, we give you one clear quote in writing before any work starts. The final price depends on the size of the site, the number of plugins, whether it is a store, and the hosting setup. You pay 50 percent in advance and 50 percent when the work is done, through Stripe or PayPal.
Keeping your site fast after the optimization
Speed is not a one-time fix. Every new plugin, every full-size photo uploaded straight from a phone, and every extra script slowly weighs the site down again. That is why we set up monitoring after the work: Core Web Vitals tracking and a performance budget, so a regression is caught before your customers report it. Many clients keep us on through our WordPress maintenance plans, so the site stays fast instead of drifting back.

Frequently asked questions
Why is my WordPress site so slow?
Usually several causes at once: oversized images, too many plugins, no caching, a bloated database, slow hosting, or a page builder loading too much code. A single cause is rare.
What is a good PageSpeed score?
A mobile score of 90 or above with all three Core Web Vitals passing is a strong result, and the target we work toward. How the site feels to a real visitor matters most.
Does speed affect Google rankings?
Yes, but only as one signal among many. Core Web Vitals are part of the page experience signals Google looks at.
Will speed optimization break my design, plugins or checkout?
No. We take a full backup first, make changes in careful steps, and test your important pages afterwards.
Why is my mobile score lower than my desktop score?
Google tests mobile on a throttled mid-tier phone over a 4G connection, so heavy JavaScript and oversized images take much longer than on a desktop.
How much does speed optimization cost?
A standard speed optimization starts from $99. The speed check and audit are free, and you get one clear quote in writing after the audit, before any work starts.
How long does it take?
It depends on the size and condition of the site. After the free audit, we give you a realistic timeframe before we start.
Why not just install a caching plugin?
A caching plugin helps, but it hides the real problem instead of fixing it. A site that needs aggressive caching to feel fast usually has a slow database or bloated code underneath.
