SerpStack vs. SerpAPI: Which is the better API for your SEO?

Analyzing search results is an important part of a wide range of SEO tools and other site management apps. If you are building anything that relates to SEO, you are going to need a SERP API.

What Is a SERP API?

Search Engine Results Page APIs can be integrated with websites and apps to pull the current top Google results for a given keyword, including featured snippets and other details.

Why Is a Search Engine API useful?

SERP APIs have become an essential tool for optimizing your site’s search results because of the increasing personalization of the search results provided by Google. 

Your search results are influenced by your search and browsing history, device, location, and many other factors. As a result, manually checking search results cannot give you an accurate understanding of how search results appear to the rest of the Internet. 

Using a SERP API to scrape results pages enables you to view the results without these personalized filters and prioritizations.
