Google is constantly improving their search engine, whether they update its looks in favor of making the results to be more eye-catching or providing it additional functions, like some product reviews that have been appearing lately. Now, apparently the web search will start displaying some cards that will lead directly to downloading some apps. For example, if a user searches for phrases like "get chrome", "download chrome" or "install chrome", there should be a card displaying the logo of the app (the Chrome browser in this case), the name of the developer and the download URL, plus a link that says "Go to download" so that the app can start downloading.
It might not seem very useful, but if you think about it, many people that are not very familiar with this process could end up downloading an app from a site that is not very trustworthy. So this could prevent software that gets disguised as popular apps and malware to get installed by mistake, as they tend to appear as search results. This functionality is not very accurate just yet, while it gets it right for some apps, when trying to download the Firefox browser, the link leads to Mozilla's homepage where users would then have to look for the download link for the browser. Clearly it is based on an algorithm based on what people search for the most and it uses it as a download link, but it is not verified.
Worst case scenario, the card appears with a download URL other than the official site of the app or its developer, which was the case when searching for "download audacity". This also proves that the algorithm is not picking up the first site that appears within the search results. For now, let's just take the new cards as visual aids and all the information must be checked before hitting the download link. These cards are appearing in the U.S., but there are other regions where they're not available just yet, so they will probably start showing in a near future in more countries with an enhanced version of the algorithm.
