More than anything, the Spanish were seeking wealth.
Christopher Columbus himself thought that he had reached India: he wanted the wealth from the trade with Indians.
In the beginning, the Spanish hoped for Gold and Silver, later also for other products that could be made cheaper in the New World.
In short: the Spanish were not interested in Mexico but in what the ships could bring from Mexico (again, mostly gold).

An archipelago, appears in the sea or an ocean, and it is a chain of large group of islands, sometimes big, sometimes small, sometimes with mixed sizes. This geographic feature needs millions of years to form, and intensive geologic activity in order to take its shape. Almost exclusively, the archipelago is a chain of islands that were formed by volcanic activity, be it in the past, or in the present.
There's lots of archipelagos around the globe, with some of the best known being the Lucayan Archipelago, Canadian Arctic Archipelago, British Isles, Tristan de Cunha, Canary Islands, West Indies, Maldives, and lots of others. They can be found in all oceans around the world, and in big portion of the seas as well.
