Website Speed Optimization Services

Start with the failing metric, not a checklist. For Largest Contentful Paint, identify the LCP element on each template (usually a hero image or heading) and make sure it is preloaded, correctly sized, served in a modern format, and not waiting behind render-blocking CSS or JavaScript. For Interaction to Next Paint, reduce and defer JavaScript, especially third-party scripts, and break up long tasks. For Cumulative Layout Shift, give every image, embed, and ad slot explicit dimensions and load fonts so they do not swap sizes. Then verify in field data, because lab scores and real-visitor scores can disagree.

Yes. Core Web Vitals have been a Google ranking signal since 2021 as part of the page experience signals, and Google has said the effect is strongest as a tiebreaker between pages of similar relevance. The indirect effect is larger: slow pages lose visitors before they engage, which suppresses the behavioral signals and conversions the site exists for. Fast, lightweight pages are also easier for search and AI crawlers to fetch and render, which affects how completely and how often they are indexed.

Caching serves a stored copy of a page to repeat visitors and reduces server work, but it does not change what the browser has to download and execute. If the page ships 3 MB of images, 40 scripts, and page-builder markup, it is still slow for the first-time visitor, and first-time visits on mobile are exactly what Google measures for Core Web Vitals. Caching is the last step of optimization, not the first. The work that moves the numbers is in the theme, the images, and the plugin stack.

It depends on the number of templates and on how much of the problem lives in the theme versus in configuration; we give a fixed timeline with the quote after the audit. Lab scores improve as soon as changes deploy. Core Web Vitals in Search Console are based on a 28-day rolling window of real visits, so the field status takes about a month after launch to fully reflect the changes. We report on both.

No. Performance work happens beneath the design: how assets load, how much code ships, how images are encoded and sized, how the server and cache behave. Dragonboat’s rebuild cut Largest Contentful Paint from 15.7 seconds to 2.3 seconds with the existing design preserved pixel for pixel. If a specific design element is inherently slow, such as an autoplaying background video above the fold, we will show you the cost and let you decide.

Google labels Lighthouse performance scores of 90 and above as good, 50 to 89 as needing improvement, and below 50 as poor, and mobile scores are the ones to watch since most traffic and Google’s indexing are mobile. That said, the Lighthouse score is a lab number. The result that affects rankings is whether the page passes Core Web Vitals in real-visitor field data: LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1 at the 75th percentile. We aim for both a 90-plus mobile score and a passing field status.
