This client purchased a Google Authority Stack focussed on a generic service-based keyword for a service they offer.
We created a Google Authority Stack with all of the Google properties, created an article using the content on their homepage and about us page and also created a CTA banner.
For the main keyword, rankings were increasing slowly for the first 2 days then jumped gradually for the past few days.
This is Google testing the content and pushing up the ranking, 70 places is quite dramatic.
These results are not guaranteed or typical as every SERP is different and competition varies.
