15+ Best SEO APIs to Automate Your SEO Strategy in 2023

How crucial is it for businesses to start using SEO APIs? The key to outsmarting competitors and attaining long-term success these days is to work smarter, not harder.

Manually carrying out your keyword research and web scraping processes will leave you losing precious time, money, and resources. In contrast, the use of SEO APIs can prove beneficial for automating your digital marketing strategies and objectives.

So, are you ready to try some of the most common SEO APIs? Read this article to learn about the importance of APIs for search engine optimization, along with the best SEO APIs to try in 2023!

What is an SEO API?

SEO APIs are application programming interfaces that allow you to easily retrieve large amounts of data from SEO platforms to be used in search engine optimization campaigns.

SEO APIs are available from many different SEO tools and platforms. Each of them owns first-party datasets that can be integrated into your SEO campaigns to gain new insights.

As an agency working on your own marketing strategy or the marketing strategies of your clients, having access to such data can prove extremely useful. And instead of gathering it manually or scraping it in various ways, using SEO APIs is the easiest way to access such data and automate parts of your SEO campaigns.

Why are SEO APIs Important?

In a nutshell, SEO APIs help you achieve better results in SEO campaigns in a shorter period of time by automating the data extraction parts.

Compared to SEO scraper tools, APIs designed for SEO purposes speed up the time it takes to complete different SEO processes while analysing all accumulated data and translating it into an extensive knowledge base for your SEO strategies.

Another key aspect of the importance of SEO APIs is their practicality.

Every digital marketing specialist knows that it takes several different apps and tools to execute their job methodically and with precision. Unfortunately, switching across multiple tools can be tedious, especially if you also have several clients and campaigns to work on. Using SEO APIs, these processes are totally simplified.

5 Top Benefits of Using SEO APIs

Here are some of the biggest benefits you can get from including SEO APIs in your digital marketing strategy:

  • Unlocking extensive features. Compared to extensions, SEO APIs contain a broader range of features that are useful if you want to tailor the data you acquire based on your campaigns and SEO KPIs.
  • Obtaining data in standardised formats. SEO data APIs are extremely useful if you need to gather data from multiple sources. Each API will provide you with unified and normalised data that will be cleaner than scraped data.
  • Enabling automated reporting. With a uniform reporting format and centralised functions from different SEO tools, you can automate your reports. Access, share, and modify the data you need without any hassles!
  • Gathering in-depth data for analysis. SEO APIs index a plethora of websites, gather information from a diverse scope of resources and conduct cross-analysis of a massive amount of datasets.
  • Enhancing social media and PPC strategies. SEO APIs can be used with APIs for PPC and social media marketing. This is especially useful if your strategy is a mix of SEO and PPC campaigns and you need to integrate the data from both.

SEO API Use Cases

SEO APIs can be quite useful. In fact, apart from enhancing keyword research, they also encompass other facets of building your brand and expanding your audience reach online.

  • Check websites’ DA. Domain Authority (DA) is essential in assessing how well websites perform and rank based on search engine criteria for quality and relevance to a niche. It also reflects the credibility of websites in the industry. Using an SEO API, you can gather the DA of thousands of websites easily.
  • Competitor analysis. SEO APIs can consolidate all key information about your competitors. They allow you to use competitor data more easily and plan your next SEO campaigns to be a step ahead of them.
  • Content curation. One of the tested-and-proven ways to attract higher traffic and clicks to your articles is to figure out which topics related to your brand or industry you should be covering. Using SEO APIs, you can easily analyse your niche to discover them.
  • Keyword research. SEO APIs also give you a clear idea about each keyword’s difficulty and search volume, giving you an idea of which keywords and phrases to prioritise in your marketing strategy.
  • Monitor backlinks. It is a must to be extra careful with where you get backlinks from. Toxic backlinks could potentially harm your website’s rankings, tarnish your reputation on search engines, and set you up for serious penalties.
  • SEO A/B testing. Also called split-testing, A/B testing is done when two different campaigns are compared to see which of the two will yield better performance on SERPs. SEO APIs can help you extract relevant data to report on the tests.
  • Website audits. A website audit is done to assess the overall performance of your website. It entails crawling every site page to check duplicate content and optimization. SEO APIs can help you get the relevant data to use in your audits.

It is essential to have a checklist of what to look for in SEO APIs and align them with your objectives. Here are some criteria worth paying attention to:

  • Pricing. If you really want to reach stellar results with your SEO strategies, free SEO APIs simply won’t cut it. You will need to pay to use some of the top SEO APIs. Compare the prices offered by each SEO API you are considering and see what best fits your budget.
  • Performance. Check the number of requests that the SEO API can handle, as well as the speed of completing them. An SEO API that can quickly respond to large requests will help you stay up to date with SEO trends.
  • Documentation. Having proper documentation along with the SEO API you choose will help you easily integrate it in your SEO strategy and along with other APIs you might already be using.
  • Timestamping. When conducting competitor analysis or keyword research, you will want to have access to the most up-to-date data. Look for SEO APIs which have it and support requests with a timeframe reference.

How to Connect SEO and PPC Data

If you are working on SEO and PPC campaigns in parallel, you might want to report on both simultaneously. One way to do this is by using SEO and PPC APIs. Or, you could build a custom solution, which is what we have done,

One of our clients, Brandcraft, wanted to analyse their SEO and PPC data together, and we helped them merge their SEO and PPC data into one centralised data warehouse.

Here’s how we were able to successfully help them achieve just that:

  1. First, we gathered SEO data with the help of Authoritas, a SaaS SEO platform that effectively aids in analysing and tracking a brand’s overall SERP performance. We also used a marketing data warehouse solution called Shape that helps collect data on Google Ads.
  2. Then, we stored all of Brandcraft’s needed data on BigQuery, a serverless data warehouse that enables data storage as well as combining data collected across different platforms.
  3. Lastly, we used a custom SQL query to combine the keywords and search terms from both platforms and then used a comprehensive dashboard to present the merged data in a comprehensible and concise format.

The end result? Brandcraft was able to dissect data from their PPC and SEO insights and devise more efficient and straightforward strategies to help them cater to more client demands.
