I want to share some experiences from within the particular niche that is wildlife photography and how it relates to species information. I've been querying such information for over 15 years.
Search for a plant species. You'll have the hardest time finding anything about the plant itself, results are dominated by parties selling the plant. Quite often not even the plant you searched for.
Search for a species of insect. Results are dominated by products on how to kill it or sensationalist misinformed articles about their danger.
Search for a species + location/country. Results include all kinds of stuff about the species (which is already poor, see above) but also simply forgets about the location parameter.
The above is a massive problem, because it leads people to believe that a species occurs in a country, whilst it may not. They then incorrectly identify the species on their photo. This error is then infinitely copied by others as it surfaces in search results, which many see as authoritative.
This still pales in comparison to the problem that is Google image search. You search for a species name but the photos returned more often than not are not the actual species. It's a photo from the same page as which the species name occurred on.
Not to mention the Pinterest problem, which absolutely grinds my gears. They get all the free search traffic for stealing people's original works. How the fuck can Pinterest rank so highly, it has no content and is never the original source.
It's hard to put my finger on the timeline, but all of the above has gotten dramatically worse during the last 3-4 years. It was definitely not always this bad. It used to kind of work.
You know what Google should do? They should directly feed from authoritative sources rather than scraping crappy content from bad actors. They do it with Wikipedia and I see no reason why they can't do it for other niches where high quality information is publicly available.
For the above niche, it's entirely solvable. Academics have open databases with species information that is trustworthy, not gamed, and authoritative. How about using it?
