I used a Google analytics platform to see what type of monthly search volumes google is getting for Warcraft 2 related inquiries.
On average 210 people search google each month for "Tides of darkness"
"warcraft 2 online" gets an additional 320 google searches.
heres some more:
590 for "warcraft 2 tides of darkness"
390 for "warcraft 2 game"
140 for "warcraft tides of darkness"
480 for "play warcraft 2"
1,000 for "free rts game"
140 for "warcraft 2 units"
210 "play warcraft 2 online"
22,000 for "warcraft 2"
Imagine if server.war2.ru was the first, second, or third website all of these people saw when they searched these terms. Imagine how many of them would then click the link to our site, and then how many might download and try the game.
This is only a small list of the potential popular or high quality searches people are doing each month for warcraft 2 or rts games in general. If you guys have any other terms you think potential new players might be searching, just let me know what it is and I'll search it for you and get you the numbers back. If you advertise on google or you are a potential google client, you can also do the searches yourself through Google Keywords Planner in your Adwords account.
Anyway, as you can see, there's a decent amount of traffic - specifically, thousands of people searching for Warcraft 2 every month on google.
How do you capture this traffic?
If you are willing to pay, you can run pay per click ads on google (aka adwords), or pay someone to do search engine optimization.
If you would rather get this traffic to your website (server.war2.ru) for free, learn best SEO practices and then put in the time, or find someone in the war2 community who already knows it and is willing to put in the time.
If done right, it would be highly likely that you steadily get lots of new players every month through SEO.
