About 70% of visitors to my automotive news website come from Google. Another 10% comes from search engines such as DuckDuckGo and Bing.
A few months ago, I started promoting it through Facebook, but without paid advertising there are not many visitors from there yet. Still, it helps increase brand awareness and brings some returning users.
I still focus mainly on SEO because for informational websites it remains the biggest traffic source. I regularly publish new articles, update older content, improve internal linking, and expand topic clusters instead of focusing only on individual keywords.
Recently, I've also started seeing some visitors coming from ChatGPT.
For another project in the services sector, direct advertising on review forums works much better, while organic traffic there is minimal.
So yes, niche websites are still heavily dependent on Google in my experience. The problem is that for many informational sites there is no other source that can realistically replace that amount of traffic. Social media, direct visitors, and AI referrals can help, but for me they are still additional channels rather than a replacement for search traffic.
