Hi tech_soul
you can find the certification paths at https://www.splunk.com/en_us/training.html
Anyway, you can stats with Fundamentals I that's frre (except the examination that costs 125$).
Than yu can follow Splunk Core Certified User path and Splunk Core Certified Power User that are the basic paths.
then it's important Splunk Enterprise Certified Admin, so you reach a good level of knowledge.
Then,if you can, I like very much Splunk Enterprise Certified Architect (I'm an Architect), but before you need to follow the other paths.
In the meantime, I suggest to follow the free Search Tutorial ( https://docs.splunk.com/Documentation/Splunk/8.0.0/SearchTutorial/WelcometotheSearchTutorial ) and all the free courses that you can find at the above link and on YouTube, then the webinars that you can find in the Splunk Partners Portal.
Ciao.
Giuseppe
