The Raw Data: 117 Stats from the Trenches

Here’s the thing…

Most link building guides give you fluff. “Build quality links.” “Create great content.” Cheers mate, real helpful.

This isn’t that.

We pulled data from 1,200+ SEO professionals. Analysed billions of backlinks. Studied 11.8 million Google search results. Then packaged every single stat that matters for Aussie businesses.

60% of Google searches end without a click.

Think about that. More than half your potential traffic vanishes before anyone sees your site.

Yet 59% of SEOs reckon backlinks will matter MORE in coming years.

Weird, right?
