Page Weight Estimator (HTML) — frequently asked questions
What is page weight?
Page weight is the total byte size of all assets transferred across the network to render a webpage, including HTML documents, stylesheets, scripts, images, and fonts.
Why does page weight matter for SEO?
Heavier pages consume more bandwidth, load slower on mobile networks, increase bounce rates, and hurt Google Core Web Vitals rankings.
What is a good target for total page weight?
Industry best practice recommends keeping total page weight under 1.5 MB to 2.0 MB for fast loading on 4G and mobile connections.
How is the website carbon footprint calculated?
Carbon footprint estimates the kilowatt-hours of electrical energy consumed per page view based on transferred bytes multiplied by average global data center carbon intensity.
Does this analyzer run on-device?
Yes, you can paste HTML markup or run audits locally with zero data sent to external servers or logged anywhere.
