SEMrush’s Analytics API
I’ve talked about the SEMrush API in the past, and with new updates being added regularly to reflect SEMrush’s current offerings, it has never been a better time to begin exploring. SEMrush’s API uses a REST framework for lean access to SEMrush’s massive and continuously updated keyword database. So it’s quick and easy to begin development and implementation with little hassle in the initial setup. And, with new additions such as their Phrase Questions (pulling questions-focused terms based on root inputs), and Broad Match Keywords (similar to their Keyword Magic Tool or Google Ads’ Broad Match Modifiers), keyword collection is a breeze. Here is a quick example script of how quick you can get started in the API.Speaking from my own personal experiences, SEMrush’s keyword capacities are best utilized for mass sourcing when you have a bulk of root terms/topics that you know will have greater depth and areas of opportunity. Being able to iterate over hundreds of root terms and storing the data in one place as led this workflow to be a core part of my own process that has saved me countless hours and given me keywords I never would have thought of on my own.
Google Ads API — Keyword Forecasting.
Taking the data right from the source, Google Ad’s API featured a robust backend data stream for grabbing the best source for search volume. So why wouldn’t I put this one at the top?Google’s APIs, especially those connected to their core advertising and analytics offerings, can have a steep learning curve in terms of jumping right in. Their documentation is impeccable and their full SDK can unlock endless opportunities. But, it can feel like drinking from a fire hydrant when first starting. SEO’s with not as strong developing skills may have larger issues with accessing the data and building lean keyword research tools compared to some of the other APIs in this article.
Typically used for enterprise-level SEO, Searchmetrics features a comprehensive keyword and domain database with a scalable API to match. With access to over 900 search engines and countries, Searchmetric’s API is a comprehensive way of gathering keyword data in niche markets where data is limited via conventional channels.While the SDK for Searchmetrics is written in PHP, its thoroughly-detailed API documentation allows for smooth integration and ease of access for any programming language.Searchmetric’s API is only available with their “Suite Enterprise” package, so utilizing their data will require a larger investment by either your clients or organization. But, with access to a larger pool of data, such as additional accessto social media data and YouTube data, Searchmetric’s API is for the keyword researcher who truly wants it all.
