I was poking around in one of my websites a few days ago and checking google rankings for a few key words. I decided to take 5 articles about the same general subject and combine them together to see what happened. All of these articles have been live on my website for over a year. After combining them all into a 2500 word 15 total images article, I laid it out like a wikipedia page. I included a ton of internal links about the same general subject, and re-wrote it a bit of it to include an asinine amount of longtails. I then obviously redirected all of those preexisting articles to the new permalink I created with a nice short clean url. None of my original articles were particularly powerful in the serps, and I was totally non existent for the major keyword I was trying to rank for. With all of those articles combined, I became captain planet baby! From nowhere whatsoever?to top 10 for a very difficult keyword in under 2 days! So, I went through some other websites of mine and did it some more. Guess what happened? More near instant results showing huge serps jumps(less than 24 hours)! If you have a website about fat kids, why not combine your article about "feeding fat kids" and your article about "chubby kids bad behavior after eating chocolate", so you can bring home that bacon? Of course if I had written these articles just like this from the beginning they would probably already be ranking well, but after a light audit; I was able to put some mediocre worthless articles together to become something special.
