Too much of the up-to-date high value information is posted onto semi-public channels. Like facebook groups, instagram posts, telegram channels, etc.
At the same time, too much of the publicly available websites are becoming clickbait and mindless marketing drivel.
Just try to research anything slightly obscure that has to be up-to-date information (from the last few years).
Like "how to get from Nairobi to Kisumu by bus". Google maps doesn't have this (not surprisingly), but what about the SERPs? Nothing there. 90% of the results are useless bus ticket sale websites that have no info, just SEO. (You can't buy this ticket online anyway).
Is Kenya just such an off-the-map destination that no backpacker has ever written about taking this route? No!
The information is out there. You'll find it inside the related facebook groups for travelers in east Africa. And if not? That's where you'll ask. But the answer? It'll never reach a SERP in the future.
Even more sad, is that if you keep looking on Google, you may find buried results from years ago. From travel forums and such. What's sad is that the info will be 10 years old, since no one uses public forums anymore. (Unless it's on reddit, pretty much the last public forum with any reach).
