When most marketers think about SEO, they jump straight to keywords like “best running shoes” or “how to do [whatever]”. Non-branded, high-intent, top-of-funnel stuff. But our latest study might surprise you: Nearly half of all Google searches (45.7%) are branded searches—meaning people are actively seeking out specific companies and products they already know. Yep, nearly…
With Google’s AI mode developments, we’re heading toward a future where search results could eventually roll up into one big AI Overview.

They won’t be able to crawl the pages, so they can’t check where those pages are linking. It doesn’t matter for traffic estimates,…
Built within these scores is an implicit assumption that the higher your score, the higher you’ll likely rank on Google. But is that actually true? To find out, I studied the correlation between rankings and content scores from five content optimization tools: Surfer, Frase, NeuronWriter, Clearscope, and our own AI Content Helper. We found weak…
AI bots power some of the most advanced technologies we use today, from search engines to AI assistants. However, their increasing presence has led to a growing number of websites blocking them.

We’re about to release the AI content detector for Ahrefs customers to use, so we decided to put it through its paces…
According to Google, AI Overviews (AIOs) had over 1.5 billion users a month in Q1 2025. That would be 18.3% of all the people on the planet or 26.6% of all internet users. That’s a massive reach. In traditional Ahrefs fashion, I wanted to do the largest data study ever done on AIOs to see…
Back in 2017, we conducted a study to answer a simple yet important question: How old are the top-ranking pages in Google?

Clients and stakeholders often ask, “How long till my website (page) ranks on top of Google?” You could say “it depends”…

Google says AI Overviews increase clicks. Cold, hard logic disagrees, and so does our research. We analyzed 300,000 keywords and found that the presence of an AI Overview in the search results correlated with a 34.5% lower average clickthrough rate (CTR) for the top-ranking page, compared to similar informational keywords without an AI Overview.
