In last 12 months I had very constant Google positions for 2 main keywords. In UK and Europe it was 1st and 2nd place and for US it was 3rd place for both keywords. I used external tools to check positions.
2 days after I migrated site to new server both keywords dropped for 1 place. Now it is 3rd place for UK and Europe (most countries) and 4th place for US. It has been 14 days since migration and it is still the same.
Do you think it is just coincidence that I lost 1 position in just 2 days after I migrated the site to new sharing host?
Time spent downloading a page is 650ms which is fine. I am worried if position drop is due bad neighborhoods. Another reason could be that if my current site IP was previously allocated to another site in the past with bad reputation.
So based on your experiences how soon does site migration to new server reflect SEO?
