My 10–12-page website feels noticeably sluggish on phones and tablets. I need you to diagnose what is holding back the loading speed and deliver a single, clean code adjustment or snippet that can be applied site-wide to bring every page up to modern mobile-performance standards. What I’m after is measurable improvement: quicker first paint, leaner payloads, and smooth scrolling without layout shifts. If minifying or deferring JavaScript, compressing CSS, setting smarter cache headers, or tapping into techniques like critical-CSS inlining will do the trick, great—just keep the solution maintainable and consolidated so I can drop it into my codebase once and benefit everywhere. Please test the finished work on common mobile breakpoints and include before-and-after metrics (Lighthouse or WebPageTest) so we can see the difference.

I can help diagnose what is slowing the site down on mobile and turn that into one clean, maintainable fix you can apply site-wide. Your brief is clear on the outcome you want: better first paint, lighter assets, smoother scrolling, and no layout shifts. I would test the issue properly, implement the optimization carefully, and share before/after performance metrics so the improvement is measurable. If you want, I can start with the audit right away.

Hello, my name is Rafael. I’ve worked on performance optimisation for multi-page websites where the goal was to improve mobile speed without introducing a fragile stack of plugins or page-specific fixes. For your 10–12-page site, I would first benchmark the current performance with Lighthouse and WebPageTest, then identify the real bottlenecks affecting First Contentful Paint, Largest Contentful Paint, layout stability and JavaScript execution on mobile. Based on that audit, I’d implement one consolidated, maintainable site-wide optimisation layer rather than scattered changes. Depending on the codebase, that may include deferring non-critical JavaScript, reducing render-blocking CSS, critical-CSS inlining, smarter cache headers, image/loading adjustments and removal of unnecessary payload. The key is to improve first paint, reduce transfer size and prevent layout shifts without breaking existing functionality. I’ll test the final implementation across common mobile/tablet breakpoints and provide clear before/after Lighthouse or WebPageTest metrics so the improvement is measurable. If you share the current stack or repository, I can quickly determine which site-wide adjustment will have the highest impact with the least maintenance overhead.

Hi — I will not install a speed plugin or paste a generic snippet before measuring the actual bottleneck. On a 10–12-page site, slow mobile performance may come from one render-blocking script, font, third-party tag, oversized asset, server response, or layout-shift source affecting every page. I’ll baseline key pages on mobile using Lighthouse/WebPageTest: FCP, LCP, INP, CLS, transfer size, request waterfall, unused CSS/JS, and caching. Then I’ll deliver one clean, documented, site-wide optimization layer—not scattered page fixes. The final fix may include deferred non-critical JS, critical-CSS delivery, font/image loading priorities, compression/cache headers, and reserved media dimensions to eliminate layout shift—but only where audit data proves value. Existing design and functionality stay intact. You receive before/after metrics, mobile/tablet testing, and the exact code/change notes for maintenance. Send the URL and CMS/stack. I’ll identify the first high-impact blocker before changing anything. Raj

I can improve you better speed of your website's homepage. We will use Google PageSpeed Insights tool to measure website's speed performance. Can you advise how you've calculated a budget of ₹1,500–12,500 INR? Having looked at you requirements, ₹30000–45000 INR would probably be a closer, fair and reasonable estimate for the amount of work to be delivered. Else, the phrase "if You Pay Peanuts, You Get Monkeys" comes to mind. Your price invite scammers and they will give you fake speed optimization. Just Google about "website fake speed optimization". Open your mind and eyes. Website speed optimisation is complex task. It takes time/efforts. It is not easy task to paste cheater code, install cheater/gimmick plugins/apps etc and call it a day. I focus on real-world speed optimization with clean code, proper browser-side logic, server-side logic that Search/AI engines actually counts. Note: Google March 2026 Core update clearly states that Manipulating website results in any term is a violation of Google's T&C, and such websites will be permanently removed from search results. Proposal price is placeholder. Discuss cost for Real speed optimization. *Beware of Site Fake Speed Optimisation. It's World's No #1 SCAM that damages web/internet business. Scammer plugins, people & apps bypass real speed tests & provide fake speed. Google, Bing, Search/AI search engines are getting better at spotting these workarounds and now removing these types of website from index.
