I am starting to add articles to the fish section of my website. My problem is that people search for content using both fish tank and aquarium in their search phrases.
How to keep your fish tank cool
How to keep your aquarium cool
As you can see there are two different words but they both have the same meaning.
The easiest thing would be to find out what gets the most searches and stick with that, however I am greedy and want traffic from both searches
Also, having an articles names How to keep your aquarium/fish tank cool would get annoying for users browsing the site because it is basically repeating the same thing twice.
I am not sure what to do and I would appreciate anyone's help.
