Although I don't have much idea about providing liquidity, I do have some ideas through which you could get new users at your website for beginning the trading.

• 0% fee is quite obvious as a new exchange shouldn't charge its users at the beginning stage of its development
• sign up bonus can be given to new users who register at your website and deposit an initial amount
• investment scheme like yobit investbox could be added to your website so that people could invest in it (but make sure the initial investment is less as people would not want to make a huge investment in a new website)
• Keep all your charges as low as possible as it will attract new users to your exchange
• you can also try doing partnership with investors or other exchanges

From my experience, the best ways are:

1. Obligatory: Having an API, for market makers.
2. Highly recommended: 0% or slightly negative fees for 3-6 months.
3. Highly recommended: Willing to accept not so popular coins, listed in just 1-2 exchanges.
4. Recommended: Signature campaign or other form of targeted crypto advertisement.

There are different possibilities.
Some exchanges try to catch traders with 0% trading fees in the first x months to get liquidity. I personally prefer this, but of course it can fail if your exchange is not attractive (in sense of usability and API).
Instead of 0%, you can also make 0.1% taker and -0.1% maker -> so maker will get money for providing liquidity.


"Hitbtc" has "maker contracts". I doubt anyone is market making at hitbtc, since the contract details are very hard, but the idea is still good:

edit:
when reading your last sentence, it sounds very much like the exchange "quoine"... they also build their own "fake liquidity" with very stupid bots. I made ton of money by arbitrage with their stupid bots, but of course all trades were reverted, since they made a loss, since it was just their fake volume.
I hate this kind of liquidity and will not advise anyone to trade at such an exchange with fake liquidity.
