What results can I expect?
This is a perfectly normal behavior:
After starting a new campaign on SERP Empire, your rankings will start to bounce. It usually happens after a few days, up to 10 after you start the campaign. This means that your positions will go up, then down, and up again, etc.
About 45 days after you start your new campaign, your rankings will then start to stabilize, usually in the highest position your website reached when its positions were bouncing. Here are the rankings of a website for 45 days after the start of its campaign:
The website was first positioned 16 for its keyword. After 8 days, its position started to bounce, from 13 to 18 and then back to 12, etc. After about 40 days, it started to stabilize at the higher position it reached: between positions 7 and 6, and even reached position 5 on day 45.
