Page Speed

Page speed is one of the few things that affects everything at once: your rankings, your conversion rate, and how visitors feel about your brand. Raiser's Page Speed module crawls your entire website and measures how fast every page loads on mobile and desktop, using the same Core Web Vitals metrics Google uses to rank you. Instead of testing one page at a time, you get a complete performance picture of your whole site — with every issue explained and prioritized, so you know exactly what to fix first.

Every Page, Not Just the Homepage

Most speed tools test a single URL. Raiser crawls your entire website and measures the loading performance of every page it finds — so slow category pages, heavy blog posts, and forgotten landing pages can't hide. You get one performance score per page, plus a site-wide overview that shows where the real problems are.

Core Web Vitals, Measured Properly

Largest Contentful Paint, First Contentful Paint, Total Blocking Time, Speed Index and Time to Interactive — the same metrics Google uses in its ranking systems. Raiser tracks all of them per page, so you always know how your site scores where it actually matters.

Mobile and Desktop, Side by Side

A page that feels instant on an office connection can be painfully slow on a phone. Raiser measures both, so you can see the gap and prioritize the experience most of your visitors actually have.

Issues Explained, Not Just Listed

Every finding comes with a clear explanation and a count of affected pages: slow server responses, oversized pages, unoptimized images, render-blocking scripts and more. You don't need to be a developer to understand what to hand over to one.

Why Does Page Speed Matter?

Page speed sits at the intersection of search visibility and user experience. It influences four things at once:

Rankings:

Google uses page experience signals, including Core Web Vitals, when ranking pages. Slow pages struggle to compete.

Conversions:

Every extra second of loading time costs you visitors. Faster pages keep people on site and moving toward purchase.

User experience:

Visitors judge your brand by how your site feels. A fast, smooth experience builds trust before a single word is read.

Crawl efficiency:

Fast, lightweight pages are easier for search engines to crawl, which helps more of your content get indexed.

Which Metrics Does Raiser Measure?

Raiser tracks the Core Web Vitals and supporting performance metrics for every crawled page:

  • Largest Contentful Paint (LCP): How long the main content takes to appear. The key loading metric.
  • First Contentful Paint (FCP): When the first text or image becomes visible to the visitor.
  • Total Blocking Time (TBT): How long the page stays unresponsive while loading scripts.
  • Speed Index: How quickly the visible parts of the page are displayed overall.
  • Time to Interactive (TTI): When the page becomes fully usable — clicks, scrolls, inputs.
  • Page Size & Requests: Total weight of HTML, CSS, JavaScript and images, plus request count.
What Usually Slows a Website Down?

The most common causes Raiser finds are slow server responses, oversized pages, unoptimized images, render-blocking JavaScript and CSS, and heavy third-party scripts. The Full Analysis view groups these issues by type and shows how many pages each one affects, so you can fix the biggest problems first.

How Often Should You Check Page Speed?

Performance changes whenever your site does — a new plugin, a design update, or a batch of unoptimized images can slow things down overnight. Re-check after every significant change to your site, and run a full analysis regularly to catch regressions before your visitors do.
