I recently had a post on one of my sites and it was a "top 10 <item name>" style post. There wasn't a ton of good information on that page, it was basically just a tablepress table with some affiliate links in it. Anyhow, it managed to land around 11 for my target search term. Yesterday, I decided that instead of just having a table with 10 items and links, I would write a brief paragraph description about each item - I figured this would help it score higher, and at the same time, would make it a nicer, more resourceful post to the end user. Whilst doing this, I determined that 3 of the 10 items were not very good and so I got rid of them and changed the title of my post from "top 10 <item name>" to "top 7 <item name>". I also changed the wordpress slug to match. After this, I went into Google Webmaster Tools and updated my sitemap. All looks good. This morning, I noticed that when I search for my keywords, Google still displays the old info - position 11. How long does it normally take for Google's cache to clean? Did I go about this the correct way? Thanks!
