How to Get Historical Search Volume for Predictive Keyword Research

Data is what empowers us to make more informed choices and take smarter risks. When it comes to keyword research, search volume data is one of the requisite components for evaluating potential traffic gains, and building an informed keyword strategy.

But, sadly enough, we can’t get sufficient amounts of this data from Google. The search volume rate in Google Keyword Planner goes back only to the last 12 months. Google Trends reveals the search interest back to 2004, but the data is vague (it’s not the actual search volume) and it’s impossible to compare more than five search terms. Some try matching Google Keyword Planner data with Google Trends data, but converting the volumes and scaling the numbers doesn’t promise much accuracy, let alone the pains of the process itself.

Nevertheless, we know that you want to deliver on your users’ expectations, and give them as much data as they need to create a powerful list of keywords. Here at DataForSEO, we’ve always seen our mission in making SEO data accessible to the SEO community.

That’s why today we’re announcing the release of the Historical Search Volume endpoint in the DataForSEO Labs API. We’ve long been working on it, and we’ve collected an extensive database containing 2.5 billion keywords with their search volumes (based on Google Ads API and Bing Ads API) back to the beginning of 2019. But we continue our mission and will keep collecting historical search volume data for you.

Meanwhile, in this article, we’ll answer the most important questions:

How to use historical search volume for actionable analytics?

While traditional keyword research focuses more on monthly average search volume, savvy SEOs know that a deep-dive into the past can reveal many hidden secrets. In particular, a year-over-year comparison of monthly search volume rates can help to identify:

  • Rising keywords and topics
  • Keywords seeing a robust growth
  • Declining keywords
  • Seasonal searches

If you were doing keyword research, you’d definitely want to take advantage of the rising keywords. These terms usually have a very low number of searches from the last year, but some increasing volume the current year. Given that, you can leverage an early opportunity to create and optimize content for these keywords before your competitors do.

Conversely, keywords with robust growth will likely mean some existing competition. Yet, these terms must demonstrate a growing search volume trend, which is very likely to continue climbing. That’s why you’d definitely want to catch the wave and enrich your keyword strategy with these terms until it’s too late and the competition skyrockets.

Unlike the above types, declining keywords should be the ones you deprioritize, as their search volume trend is going down. This approach of keyword analysis helps to understand what terms to avoid adding to your keyword lists, and what content or web pages should be optimized for more promising keywords.

As for seasonal keywords, these are the ones generating the highest volumes at specific times of the year, such as Valentine’s Day, Christmas, or Super Bowl Sunday. Sure enough, you need to go further than 12 months back in data to accurately evaluate such terms and the potential gains they may bring you. For this case, the year-over-year comparison is vital. This approach to keyword analysis will help you pick the best-fitting topics, and secure additional traffic during specific seasons.

How to leverage historical search volume data in your tool?

As you can see, historical search volume has a great value for different keyword research tactics. Below we’ll reveal a few examples of how you can empower your keyword research tool with handy new features your users will certainly appreciate.

Starting from the basics, you can simply add a year-over-year difference column. In this example, the difference is displayed in percentages, accounting for the change in the past 12 months. However, with DataForSEO Labs, you can calculate the trend back to 2019.

Taking this further, you can also add a separate view (or a graph representation) for monthly search volume trends dating back to 2019. For large-volume keyword lists, a graph from the example below should be the most optimal choice.

However, you can also add a more deep-dive keyword overview section, where users can select specific periods and see more details on the monthly trends.

Alternatively, you could go a different way and add views for specific keyword types based on their search volume trends. For example, a user would enter a keyword into your tool, and it would provide them with relevant keyword ideas automatically grouped into:

  • Rising
  • Growing
  • Declining
  • Seasonal

Here’s a possible way to implement a seasonal searches view:

Pivoting this a bit, such a feature (or even a separate tool) can also be convenient for SEOs who already have their keyword lists, but need to further analyze and group them. To help them out, you could introduce a keyword import option and automatically group keywords while also displaying their metrics.

Now that you know the value and practical use of historical search volume data, it’s time to tell you how and what exactly you can get with DataForSEO Labs API. Spoiler: you’ll get more than just historical search volume.

How to get historical search volume with DataForSEO Labs API?

Designing the Historical Search Volume endpoint, we’ve tried to make it a comprehensive datasource for your keyword research needs. Most importantly, it will supply you with Google search volume rates from the beginning of 2019 up to the latest months’ data. On top of that, we’ve enriched the endpoint with:

  • Current monthly average search volume rate
  • Current competition values in paid SERP
  • Current cost-per-click values
  • Product and service categories each keyword falls into
  • Related SERP data (number of results, relevant URL, and SERP features)

Conveniently enough, you will get historical search volume data for both Google and Bing at once. Data on Bing monthly searches for each keyword will be provided in a separate “bing_keyword_info” array.

Historical and current metrics are based on Google Ads API and Bing Ads API. We’ve collected data on around 2.5 billion keywords, and we keep amplifying our database.

The Historical Search Volume endpoint works in the Live mode, which means you’ll obtain the results right away in response from our API. Below, you can find request and response data for a sample keyword list:

How much does it cost?

Overall, the billing for the Historical Search Volume endpoint works the same as for other endpoints in DataForSEO Labs API. Your account will be charged $0.01 for setting a task and $0.0001 for each data row you will receive in the results array.

Note that the maximum number of keywords you can specify when configuring your request to the Historical Search Volume endpoint is 700. Accordingly, 700 is the maximum number of items you can obtain in response.

Simply put, you specify 700 keywords and set a task:
— $0.01

You receive a response from our API with data on these 700 keywords and in the results array:
— $0.07

Overall, your account is charged $0.08.

Taking this a few levels up, if you need to get historical search volume rates for 7,000,000 keywords, you need to set 10,000 tasks (specifying 700 keywords in each), and you’ll pay $100 for that. Once you receive results for these 7,000,000 keywords, you’ll pay $700. In total, it will make $800 for data on 7M keywords.

Note that we’ve collected an extensive database of keywords, however, the depth of available historical data may vary depending on the location and language combination you set for the specified search terms.

Also, we’d like to highlight that we’ve taken care of no extra spendings for you. One request you make to our API can contain up to 700 keywords. Yet, in case our database doesn’t contain some of the keywords you specified, they will not be returned in the results array, and you won’t be charged for them accordingly.
