Over the past week, I have experienced a significant decline in my SERP for about 20 high value keywords. I have worked extensively to build a link profile by the following:
1. Submitting to directories
2. Ghost blog writing
3. HARO interviews and postings
4. Article submission to blog sites
What can I do to try to find the cause of this decline? How can I determine if it was something google changed with their algorithm or if it was my SEO strategy that was wrong?
I would rather not post my url.
