How much does a website or online store actually cost?

Four key figures from a Google and Deloitte study. They apply equally to service websites, WooCommerce stores, and Google Ads landing pages.

53%

Mobile users are leaving the site...that takes longer than 3 seconds to load. Does your store take 5 seconds? You’re losing more than half your traffic before anyone even sees your products or adds them to their cart.

+8%

Conversions 0.1 seconds faster in retail stores. Every hundred milliseconds affects how many users complete their purchase. A slower store = more abandoned carts.

2021

Core Web Vitals is an official Google ranking factor Since June 2021. The red metrics show that you’re falling behind competitors who have already optimized their sites. Lower SEO rankings = less organic traffic = fewer leads and shopping carts.

CPC↑

Quality Score in Google Ads depends on PageSpeed. A slow landing page or product page means a higher cost per click. A slow online store doesn't just mean fewer conversions—it also means higher sales costs.

You’re losing conversions, dropping in rankings, and paying more for ads. PageSpeed doesn’t send email alerts, so you only find out about it when you start comparing month-over-month figures.

How does the 90+ or 100% money-back guarantee work?

In the WordPress industry, this is the norm: you commission an optimization, receive an invoice for 20 hours of work, your PageSpeed score is still 47, and the agency says, “It’s the hosting’s fault.” You paid for the work, not the result. Speed Boost turns that logic on its head.

Market standard

You pay by the hour, not for results

Hourly pricing is a conflict of interest: the longer it takes, the more the agency earns. The risk is on your side, the margin on theirs. If PSI doesn't jump, you'll hear “let's add a few more hours".

Speed ​​Boost

You either pay for 90+ or you don't pay

Fixed price of PLN 2,500, outcome-based guarantee, PSI 90+ on mobile and desktop, publicly verified with Google's tool. No result, full refund. The faster we deliver, the better for both of us.

What we guarantee

PageSpeed Insights will show a score of at least 90 on mobile i 90 points for the desktop version of the homepage. This is a public test using an independent Google tool—you can check it yourself, without our supervision and without our screens.

What do you get if you don't

Full refund of PLN 2,500. The result is decided solely by the PageSpeed Insights score, Google's independent tool. You verify that PSI really shows below 90 on mobile or desktop, and we refund the money within 7 business days. No interpretation on our part, no judgment on yours: only the public measurement counts.

What does "no negotiation" mean?

When optimization efforts fall short, our competitors suggest “putting in more hours,” “changing the scope,” or “it’s probably just the cache.” Not us. If we don’t hit 90+, we refund your money. Plain and simple, with no attempts to convince you that “we almost made it.”

PRE-CHECK · 15 MIN · FREE

Before you spend PLN 2,500, check whether the 90+ guarantee is real on your website

Leave your website URL, hosting and email address. In ~15 minutes Claude (our internal AI auditor) will check PageSpeed, hosting, heavy plugins and send you a report with the decision: green (you qualify), yellow (with less warranty) or red (you need a deeper intervention than Speed ​​Boost). No automatic subscription to the newsletter, no sales calls - a report via e-mail and that's it.

  • We protect you (and ourselves) from the situation „I bought it but the warranty is impossible to deliver, so I'll refund it anyway"
  • Pre-check costs nothing and does not oblige you to anything
  • If you want to skip: order Speed ​​Boost directly

If you don't specify, Claude will estimate based on the page's HTML.

Free. No sales calls. Newsletter only if you check the checkbox above.

Questions and Concerns

Does my website or online store qualify?
Yes, if you have low PageSpeed ​​scores on your WordPress or WooCommerce store, you qualify. The only exclusions are dedicated applications (React/Next.js/headless), database optimization and mass conversion of thousands of images, these three areas are priced hourly, separately. Everything else is PLN 2,500, non-negotiable. A free 15-minute pre-check confirms coverage before payment.
I have a dedicated application (Next.js, Three.js, headless). Will Speed ​​Boost help me?
NO. Speed ​​Boost only supports WordPress. Dedicated applications (React, Next.js, Three.js, headless) require access to the repository, building process, and code review. This is an hourly, individual quote, not a standard product. If you have a dedicated application, write in the „list of plugins" field during the initial check and we will quote separately.
Will a website or online store maintain a score of 90+ forever after using Speed Boost?
No. PageSpeed Insights is a dynamic metric. It depends on your hosting, the plugins you add, new products and images, and external scripts. After 6–12 months, a typical website’s score drops by 5–15 points. Speed Boost guarantees a score of 90+ on mobile and desktop on the day of implementation. We’ll leave it up to you to maintain that score.
Can I negotiate the price?
No. 2,500 PLN is a fixed price. The Speed Boost model is designed for simplicity: one price, one plan, one warranty. Negotiations undermine the product’s business model. If this price doesn’t fit your budget, you can try a plugin like WP Rocket on your own.
