66.31% of all web pages have zero backlinks

Ahrefs analysed over 1 billion pages indexed in Content Explorer, the company’s content discovery database, and found that roughly two-thirds of them had no external backlinks pointing to them at all. The link graph of the open web is heavily skewed: the share of pages that pick up any referring domain is the minority, while the long tail sits effectively invisible to search engines that still treat backlinks as a primary ranking signal. For anyone publishing content, the practical read is that the bar for standing out on links is lower than it looks. A modest but consistent link-building rhythm, even just a handful of relevant referring domains per page, places you ahead of the majority of the web before anything clever about technical SEO or on-page quality comes into play.
