SEO is great, by all means. But truth be told, it is equally draining.
Chances are you probably have an army of tools to make your workflow easier. Yet, we all know that often, it can be a pain to integrate all that software seamlessly.
Sometimes, it seems like ‘seamless’ is only that word marketers use on their landing pages, but, in reality, a solution like this doesn’t exist.
If that sounds like you, you have to try using SEO APIs more.
This guide is for those who are tired of trying to wade through a jungle of tools. And those for whom doing their day-to-day SEO tasks feels about as appealing as scrubbing their skin with sandpaper.
No need for more introductions; let’s get to the point.
Wondering What an SEO API Is?

The best part about APIs is that, today, they can cover any possible SEO need you have. All these opportunities are amazing. The only issue is that there are so many options that it’s easy to get lost.

On that note, these are the SEO API tools we’ll cover today:

Services for Comprehensive SEO Analysis
Nine times out of ten, people hear SEO tools, and they immediately think of these popular (and maybe even a little cliché) brands. They’re so famous for a reason, though.
That’s why let’s address the elephant in the room first, and after that, we can move on to more specific API tools.
So, here are comprehensive APIs for full-scale SEO analysis:
Ahrefs API

Top SEO Ranking and Position Monitoring Tools
When marketers talk about SEO ranking API trackers, they mean services that track a website’s positions based on keywords. Why does this matter?
- Well, monitoring your keyword ranking position lets you know the pulse of your online presence. How else will you catch when it’s flatlining, and you need to do something quick to bring it back up before it’s too late?

SEO Tool API and Services for Backlink Analysis
Ever heard an SEO expert talk about how difficult it is to build backlinks? It gets even worse when you try to do it without any helpful SEO tool APIs.
That’s because it’s not one of those times you can simply go with the gut, especially if you buy backlinks from time to time. Spammy links are still a thing, and they can be a nightmare to fix.

- Spot harmful and toxic links (and avoid those) before they tank your site rankings;
- Find unique opportunities for quality link building (competitors' backlink analysis, anyone?);
- Get data insights on your campaign effectiveness;
- Receive real-time alerts on lost or broken links;
- Quickly hone in and filter sites based on specific metrics for your link-building campaigns;
- Weed your backlink profile from time to time to ensure it’s thriving just fine;
- And, of course, speed up your link-building process and workflow.
With that being said, each of the tools below can be a great asset, depending on your particular need at the time.

Services for Technical SEO Audits and Website Analysis
There’s a lot that can go wrong with your site without you even realizing this on time. Sometimes, you can have the best products/services, create killer copy, and still get no traffic.
What could be wrong? The culprit is usually a technical on-page SEO issue.
Maybe you didn’t fix the meta tags properly, and now your blog piece has been banished to the dark side of search result pages where no one can find you.
Maybe your page takes forever to load, and as no one wants to stare at the buffering wheel of doom, they exit to go check out another site.
While these issues are not so bad at first, it gets worse when you don’t do anything about the problem on time. This is where using SEO check API tools that help you automate your audits and analysis is a no-brainer. On top, you get perks like:
