Benefits of SEO APIs – Experts Share

1. Access More Data

“APIs allow you to access data from multiple sources in one place, so you don’t have to waste time jumping from tool to tool. So instead of logging into different tools and platforms to gather information, you can use an API to pull data from different sources and analyze it all in one interface.” Jessica Rodley, Director of Operations at Dialed Labs

2. Minimize Manual Efforts

“By integrating SEO APIs into our workflow, we have automated many of the tedious and time-consuming tasks that come with SEO. Imagine pulling keyword data and search volume metrics directly into your keyword research tools, all at the click of a button. It’s like adding a turbocharger to your SEO engine and boosting your productivity like never before.” Maria Harutyunyan, Co-founder at Loopex Digital.

3. Keyword Research

4. Backlink Management

“For starters, it streamlines backlink management. I can automatically detect when SetSail gets a new backlink to our site.

Then, I identify other potential backlink opportunities using the API to identify what high authority sites rank to competitors but not us.” Lee Moskowitz, Director of Growth Marketing at Setsail.

Undoubtedly, APIs are useful SEO tools for marketing.
