I actually experience a ranking increase yesterday. The highest I've been when its hovering around the upper mid of page 1. I know people would have been happy with that but I decided to change the seo title, played a bit using variations so it doesnt look the same with competitors. I made sure I use the targeted keywords though. I also added a bit more words in the article. I then asked Google to reindex the page, so the seo title would change immediately and people could see it. While it did change, my ranking has dropped badly.. like down to about 10-12 positions. Is this normal? And has people experience their rank come back after this?
