Hacking Google : Tips & Tricks

• Free Downloads of any type
• Ever needed an old Android app but couldn't find the APK for what you were looking for? Or wanted an MP3 but couldn't find the right version? Google has a few search tools that, when used together, can unlock a plethora of downloads: inurl, intitle, and filetype. For example, to find free Android APKs, you'd search for -inurl:htm -inurl:html intitle:"index of" apk to see site indexes of stored APK files
• -inurl:htm -inurl:html intitle:"index of" apk
• intitle:"index of" downloads
• filetype:pdf Javascript

• Search Product, Recipes, and More with Reverse Image Search
• With Google, you can just drop a picture into Google Images and it'll search for similar pictures. 

• Get google cache copy directly
• We all know Google Cache can be a great tool, but there's no need to search for the page and then hunt for that "Cached" link: just type cache: before that site's URL
