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
