This speeds up the process of finding the first peers. The main advantage for Bittorrent indexers is that they do not have to store the torrents on their servers anymore which could be beneficial for them in several ways.
It could reduce the pressure from the media creation industry and reduce hardware infrastructure expenses thanks to less tracking and downloading. The end users on the other hand benefit from Magnet Links as well. All they need is the link to start downloading the files which makes them independent from torrent indexers.
It also allows them to distribute the information more easily. Torrent indexers remain on the other hand the main source of information for new files that are available for download.
A tracker less environment should raise a question of identification. How can a download be initiated ff there is no tracker to inform the Bittorrent user about other users who download and seed the file? The answer is DHT, Distributed hash tables. DHT is enabled by default in popular clients such as uTorrent or Vuze. Without going into to much detail, the hash of the magnet link is used to find peers using DHT.

So, why magnet links? Also, for sites to share files the server with the torrent files must be up and available to all parties thus leading to hardware infrastructure expenses. Namely somewhere that everyone can always access.
This is not always as convenient as the magnet link. The magnet links also get a file, but in a different way. The torrent system relies in part on seeding and leeching uploading and downloading - so file creation processes are available to others upon receipt and magnet links take advantage of that.
Links connect users to anyone who has files available for download.
