Sitebulb gives me full control over what data I need to analyse, I get to pick and mix exactly which audit options I want to run in each crawl. Crawl comparison, data on a URL basis and chart exports are all a click away - making it very easy to communicate my findings. And yes, we all love to see and show off their interactive crawl maps! Their performance reporting is a game-changer, making it accessible to slice and dice my data, set performance budgets and identify opportunities.

Collect Web Vitals lab data in bulk

Googles Web Vitals initiative has changed the game when it comes to website performance testing, shifting the focus to user-centric metrics and mobile device emulation, allowing us to better understand what the user experience feels like to website visitors.

The natural limitation of the main analysis tools, Lighthouse and PageSpeed Insights, is that they can only analyse one page at a time.

Utilizing its unique headless Chrome crawling environment, Sitebulb can collect Web Vitals 'lab data' as it crawls. This allows you to spot potential problem areas based on a large sample of the website, rather than simply looking at a single page.

Bulk Web Vitals Metrics

Based on the Web Vitals scores, Sitebulb can also grade all the tested URLs, allowing you to see the distribution of pages based on their performance, and easily deep-dive into the worst performers.

URL Performance Scores

Perform Lighthouse performance tests, for every single URL on your site

Easily see where you are going wrong, with Lighthouse's industry-standard audits, which are checked against every single URL on your website, and split out into Opportunities and Diagnostics.

Identify the common factors that are affecting lots of pages, allowing you to prioritize your recommendations more effectively.

Lighthouse Performance Tests

Utilise performance budgets to keep page weight down

Set quantity-based limits for page resources, and check that every page is under budget (e.g. 'total image size less than 1000KB').

This gives you a pass/fail result for each resource type on every page, so you can identify which pages are over budget or which resources are causing page bloat.

Ensure mobile rendering works smoothly

Sitebulb also checks the most important elements for mobile rendering, telling you exactly which URLs fall down on specific elements, so you can identify issues with ease.
