http redirects to https: how the world's top websites do

Of 532 of the world's most popular websites that we audited, 480 pass this check and 52 fall short.

What this check means

Visitors who type or follow an old http address should be sent to the secure version. Without the redirect, both versions exist and the insecure one can be served.

How this was measured

The figure comes from Adnave's own audits of 551 popular websites, each read as a search engine first receives it and re-checked about once a month. A site “falls short” when the result is anything other than a pass. That is not always a mistake: a very large site may skip something on purpose. Sites that refuse automated visits are not in the sample, so the figure describes the popular sites that could be read, not the whole web. Full method and limits
