My verdict: the budget SERP API for data-driven SEOs.
ScaleSERP does the job of SerpApi for less. Perfect for monitoring at scale. The API for scraping Google search results (SERP) at scale. ScaleSERP returns Google results (organic, ads, featured snippets, etc.) in JSON. Ideal for SEO monitoring, keyword research, or automated competitive analysis. Starting at $50/month for 5000 searches. SerpApi competitor, often cheaper. If you do data-driven SEO, it's indispensable.
What I like less: it's an API, so not accessible to non-developers. And if you just need to check a few positions, it's overkill.
My advice: compare ScaleSERP and SerpApi for your use case. ScaleSERP is often cheaper for equivalent features. If you're starting out, begin with the basic plan and scale as needed.
