Yes, it earns a lot, but things are not as easy as they seem.

Almost everyone dealing with website affairs focuses on how to increase their earnings further. The general argument on this subject is that English sites earn more.
Personally, I do not agree with this view. As for the reason, English and Turkish sites have different competition rates. If a person working to drive traffic to an English site works equally hard for a Turkish site, they will earn roughly the same money on average. They might even earn more.
In other words, if your Turkish site has 10,000 competitors, your English site will have 100,000,000 competitors. Consequently, the earning rate will decrease.
Driving traffic to an English site is much harder than driving traffic to a Turkish site. Even if you are a professional English speaker, the sheer number of competitors, the education level in foreign countries, and the abundance of information sources make things difficult.
Countries with high education rates cause you to struggle with stronger competitors.
90% of Turkish sites consist of junk sites. This implies that your competitors are weak. People who don’t even know spelling rules are chasing after making a lot of money by opening copy sites. This situation benefits site owners who do their job well and paves the way for them.
The same does not apply to your English competitors. Because a person educated in Canada cannot be compared to a person educated in Turkey.
If your English site reaches a good position somehow (by working very hard) and offers a unique service, then it brings in the money.
My suggestion is;
You should devote the time that should be allocated to an English site to a Turkish site, work hard, and be different from the others. You will see that you earn more from your Turkish sites in proportion to your work.
These are my personal experiences and opinions. Go ahead and share your thoughts too, friends. Have a good time on the forums everyone.
