I was in #8 position for a 10k global search keyword and I changed my onpage seo about 10 times in the span of 2-3 days to test what would work best for penguins optimization algo. I would add or remove some keywords and then submit the site to be crawled and see the fluctuations. Once I found out the onpage copy that worked best for me I changed it to that but instead of my site gaining in rankings, it fell to page 4. I then changed my copy a few days later and added some LSI keywords I wanted to rank for and the site dropped to page 6. I changed it again a few days later and it dropped to page 9. Now it's floating between pages 10 and 20.. Im worried that me changing my onpage too many times in a short span has triggered something in google. Has anyone else had this happen to them & is there any way to recover my page 1 rankings?
