Testing and Debugging — Flawless Performance for Your Site
When you choose our team for site development, you can be sure: testing and debugging are a built-in part of our services, already included in the price at every tier of work. We don't promise "zero failures ever" — no platform can honestly claim that. What we do promise is this: before launch, the site is checked against typical scenarios and devices, and if something does break, you know who to call, and we fix it.
What testing includes when we build your site
- Functional testing — we check every button, form, filter, cart, and payment flow
- Cross-browser compatibility — the site displays correctly in Chrome, Safari, Firefox, Edge
- Responsiveness — we test on real devices (desktops, tablets, phones of various screen sizes)
- Load speed — we optimize code and images for a PageSpeed score of 85+
- SEO check — valid markup, correct meta tags, structured data
- Security — vulnerability checks, spam protection on forms, SSL configuration
All these checks happen before the site is handed over to you. You get a product that's fully ready to work.
Testing and debugging sites built by other developers
If your site was built by another company and you're running into problems, we can help. We offer a full range of testing, debugging, and optimization services for sites on any platform (WordPress, Bitrix, custom-built solutions, frameworks).
What we check and fix:
- Functionality check
We thoroughly test every aspect of your site, making sure all functions work correctly. We check contact forms, interactive elements, catalog filters, shopping cart, payment, the user dashboard, CRM integrations, and other features. The goal is to make sure visitors can interact with your site smoothly, without bugs or glitches. - Bug fixes
If testing turns up errors, unfinished work, or conflicts, our specialists get to fixing them right away. We work with code at any level of complexity: from simple HTML/CSS tweaks to complex PHP, JavaScript, or Python logic. We leave no room for failures, aiming for flawless performance from your site. - Performance optimization
We pay special attention to your site's load speed. Fast page loading is key to both visitor satisfaction and SEO ranking. We optimize code (minification, removing unused JS/CSS), compress images (WebP, lazy loading), configure caching, and connect a CDN. The goal is a PageSpeed score of 85+ and a load time of 1-2 seconds. - Adapting to different devices
We make sure your site displays correctly on every type of device: desktop, tablet, mobile phone. We build responsive layouts and test on real devices with different screen resolutions. We deliver an equally good experience to every visitor, no matter what device they use. - Fixing critical security issues
We check the site for vulnerabilities: outdated CMS and plugin versions, unprotected forms, SQL injection, XSS attacks. We update software, close the gaps, and set up protection against spam and bots. We install or renew SSL certificates for a secure HTTPS connection. - SEO audit and technical fixes
We check the technical SEO side: correct meta tags (Title, Description, Open Graph), Schema.org structured data, the XML sitemap, robots.txt, duplicate pages, broken links, redirects. We fix any problems we find that get in the way of indexing and search rankings.
How testing a third-party site works
- Initial audit (1–2 days)
We analyze the site's current state and identify critical and non-critical issues. We put together a detailed report with priorities: what needs urgent fixing and what can wait. - Agreeing on the work plan
We give you a list of the problems found, with a description and the cost of fixing each one. You decide what to fix first, and we put together the final scope of work. - Debugging and fixes (from 3 days)
We get to work: fixing bugs, optimizing code, improving performance, closing vulnerabilities. The timeline depends on the scope of work and the complexity of the issues. - Retesting
After making changes, we run a full round of functional testing to confirm every issue is resolved and no new bugs have appeared. - Handover
We provide a report on the work done, describing every fix, along with recommendations for ongoing maintenance and a warranty on the work performed (usually 1 month).
Typical problems we solve
- Slow loading — the site takes 5–10 seconds to open instead of 1–2
- Broken display on mobile — elements overlap, text is unreadable
- Broken forms — submissions don't send or never reach the owner
- Cart and payment errors — products won't add, payments fail
- Plugin conflicts — part of the functionality stopped working after an update
- Indexing problems — the site doesn't show up in Google/Yandex search
- Security vulnerabilities — the site has been hacked or is under constant spam attack
- Broken links and 404 errors — visitors land on pages that don't exist
Service cost
The cost of testing and debugging a third-party site is calculated individually, based on:
- Scope of work — the number of problems found and how complex they are
- Urgency — express debugging within 24–48 hours costs more than scheduled work
- Future plans — if long-term cooperation is planned (hosting with us, technical support, promotion), the price of the initial debugging round may be reduced
The initial audit (identifying problems and drafting an estimate) is free. You get a full report on your site's condition with no obligation to work with us further.
Quality guarantees
- Full testing before handover — we don't hand over a site until we've confirmed everything works
- Documentation — a detailed report on the work done and instructions for use
- Warranty on fixes — if a problem returns through our fault, we fix it for free
- Support after handover — we advise on running the site and help with questions as they come up
With our team, you can be confident your site will run at the highest level — ready to attract clients and deliver a reliable user experience.
