With the rise of blogs, review sites, and social media platforms, the opinion of the online community has become a vital factor for business performance.
At DataForSEO, we’re always striving to stand on top of the industry trends, so now we’re presenting a new solution – Content Analysis API. It is designed to help you quickly obtain sentiment insights from web mentions to gain a deeper understanding of the consumer mindset.
In this article, we will walk you through the basics of sentiment analysis and will explain a few more advanced principles of using sentiment analysis APIs for brand management projects.

What’s sentiment analysis and how do businesses benefit from it?
Sentiment analysis, also known as opinion mining, is the process of inspecting a given text to determine the author’s attitude towards the described topic as positive, negative, or neutral.
These three types of sentiment are called sentiment polarity. However, classifying the polarity of a text is only a basic way to perform sentiment analysis. More advanced approaches go beyond polarity and discern emotional states, such as anger, sadness, and happiness.
Besides that, the levels of positivity/negativity and the strength of the discovered emotions can be quantified. That is, each sentiment can be assigned a score, for example, from 0 to 100, where 0 means no such sentiment present, while 100 means the text is 100% positive/negative or the author is 100% happy/sad, etc.
Commonly, sentiment analysis is performed on textual data from across the web that contains mentions of a person, brand, or product.
Opinion mining has numerous applications in ecommerce, marketing, advertising, and market research. Sentiment analysis insights collected from a variety of web sources can help businesses improve their product features, store locations, pricing, customer experience, marketing campaigns, and more.
Given the abundance of user-generated information and the vast variety of resources where it can be discovered, gathering and analyzing all the data manually would be extremely time-consuming. That is why companies and individuals turn to automatic methods and solutions for sentiment analysis insights.
How to develop a sentiment analyzer and what are the main challenges?
Automated sentiment analysis is usually based on natural language processing (NLP) and machine learning (ML) algorithms, that programmatically determine the emotional tone of a certain text.
In general, there are three ways to train and implement sentiment analysis models which we’ll review below.
Fully automatic
Sentiment analysis is based on ML techniques and self-learning. The algorithm processes certain pre-labeled datasets and learns from them until it can independently identify the sentiments of previously unknown pieces of content.
In this way, it is possible to go through vast datasets faster. However, in some cases, it might be difficult to understand why a certain text was interpreted as positive or negative.
Rule-based
The algorithm uses manually crafted rules from lexicons – lists of words and phrases along with emotions they bring to a text. The system learns a certain set of lexicons and classifies the nature of a given text based on the prevailing group of words.
On the one hand, this approach seems pretty straightforward and allows tracing back the reasons behind specific classifications. On the other hand, it makes the analysis rather limited and might produce misleading results.
The thing is, human language allows employing a wide variety of expressions to convey our emotions, and it is impossible to create an extensive list of all emotional words and their meanings in all possible contexts. For example, kill this feature vs killer feature or it’s killing me vs you’re killing it. We will elaborate on this further in this part.
Hybrid
The hybrid approach represents a mix of two previous methods. Accordingly, it encompasses their advantages (scalability and transparency) and eliminates or at least minimizes their shortcomings.
Challenges
Now, getting back to the challenges associated with sentiment analysis implementation models. Primarily, they arise from the complexities of human languages. Here are some of the most common cases where algorithms struggle with identifying the tone:
- Comparisons. The coffee here is tastier than at Starbucks.
- Contrast. Well yes, but actually no.
- Idioms. Not my cup of tea.
- Irony and sarcasm. I just love having to wait!
- Online language, emojis. Ur new store is just LOL 😀
Worth taking into account that the examples above illustrate some of the challenges with one language only – English. However, the more languages you want to add to your model, the more complications you will encounter. Above all, multilingual sentiment analysis requires a lot of additional preprocessing and coding.
This brings us to another great challenge related to sentiment analysis automation. The thing is, developing and training your system requires being well-versed in programming, data science, and computational linguistics. On top of that, learning NLP concepts and training a text and sentiment analysis model takes plenty of time and resources.
Given these reasons, companies looking to add sentiment analysis functionality to their analytical solutions usually lean towards ready-made technologies, such as APIs.
What is a text and sentiment analysis API?
A sentiment analysis application programming interface (API) is a technology that allows developers, business owners, and analysts to access sentiment analysis data without having to run complex machine-learning algorithms.
In a nutshell, API operates as a communicator between the application that receives data and some state-of-the-art system that processes texts and labels the sentiments in them.
In contrast with spending loads of time to build your own sentiment analysis infrastructure and investing in extra resources, sentiment analysis APIs will allow you to connect the service with your software, custom dashboard, or reporting tool using only a few lines of code. What’s more, reputable API providers, including DataForSEO, usually offer free integration assistance.
Depending on the way sentiment analysis APIs operate, they can be divided into two categories:
For an automatic collection and analysis of mentions by a user-defined keyword.
For sentiment recognition by a user-defined URL.
The second type of API where a user can manually pick the necessary resources for analysis is a good opinion for small-scale research. At the same time, the first type is better for larger research and software development projects that require higher automation and greater scalability.
At DataForSEO, we provide a scalable and affordable solution for sentiment analysis and brand monitoring – Content Analysis API. We’ll tell you more about it in the next part.
How does Content Analysis API determine the sentiment of web mentions?
DataForSEO is a company that’s always striving to offer more innovative approaches to data analysis. One of our latest releases – Content Analysis API – will provide you with a hassle-free way to discover citations of the target keyword or brand from across the web, and analyze the sentiments around it.
To begin with, we’ll walk you through the features offered in Content Analysis API.
First off, it supports over 70 languages. Secondly, on top of identifying and scoring positive, negative, and neutral polarity in any text, Content Analysis API detects the level of the following emotional reactions: anger, happiness, love, sadness, share (desire to share content), and fun.
You can get data on your keyword or brand mentions using the following endpoints:
- Search for all citations of the target keyword and details about each citation.
- Summary of citation data available for the target keyword.
- Sentiment Analysis of citations distributed by positive, negative, and neutral sentiment polarity and by sentiment connotations.
- Rating Distribution of citations along with their details.
- Phrase Trends, that is, citation stats by date for a target keyword.
- Category Trends – citation trends by date in a target category.
Using the Search endpoint, you can apply custom filtration to the dataset that will be retrieved. You can find more information by referring to Filters in Content Analysis API.
Now, let’s take a quick look at how the API works.
Content Analysis API relies on machine learning algorithms trained on vast volumes of carefully selected data. Our model is implemented on the hybrid method, so we can always manually modify the sentiment detection rules which ensures the highest possible accuracy of our product.
Overall, our system is designed to make the API lightning fast and your experience with it – as smooth as possible.
Using Content Analysis API, you will be making only POST requests, and the results will be provided in response right away. You can send up to 2000 API calls per minute.
Here’s an example request and response from the Search endpoint.

You can always get more code examples and all the necessary information about Content Analysis API from our comprehensive documentation. If you need integration assistance, don’t hesitate to reach out to our proactive support team available 24/7.
Last but not least, DataForSEO offers Content Analysis API on a pay-as-you-go basis and the pricing is more than affordable. Using this solution, you can perform brand analysis or craft your reputation management software under budget.
To learn a few practical insights about building a custom tool, keep on reading.
What brand management features can be built with Content Analysis API?
The development of sentiment analysis and brand management SaaS tools is becoming increasingly popular. It’s not surprising given that these solutions enable users to find brand mentions and categorize emotions in texts in a matter of a few clicks. Besides that, the pricing of existing software in the market is quite heavy, so many companies and brand experts build custom reporting dashboards.
Before you start developing your tool or dashboard, make sure you have an accurate sentiment analysis system in place. Alternatively, you can opt for a commercial sentiment analysis API that will supply you with all the necessary data right away. In this way, you will not need to pay any maintenance costs.
Here, we will show you how to create several essential brand management and sentiment analysis features using DataForSEO Content Analysis API. While there are a ton more features to explore, we will focus on these five:
- Web Mentions Overview
- Sentiment Polarity Summary
- Sentiment Over Time
- Sentiment Over Time By Category
- Sentiment By Rating
Web Mentions Overview
A quality overview of web mentions gives users all details about the citations of the target keyword they enter. Usually, these details are organized in a view similar to our sketch.
To obtain data for this feature, use Content Analysis API – Search endpoint. The parameters you should use in the body of your POST request are rather intuitive:
- Use
keywordto define a target keyword - Use
filtersto filter the results by country, polarity (e.g. negative), etc. - Use
order_byto sort the results in a certain order
Example request:
[
{
"keyword": "logitech",
"filters": [
"country",
"=",
"US"
],
"order_by": [
"content_info.sentiment_connotations.anger,desc"
],
"limit": 5
}
]
The results will contain the snippet of the mention’s text, text category, the URL where the mention was found, domain and URL rank, country, content quality score, sentiment polarity scores, and scored sentiment connotations (anger, happiness, love, sadness, share, fun).

Sentiment Polarity Summary
You can implement this feature by using data from the Content Analysis API – Summary endpoint.
Simply indicate the necessary keyword in the request’s body and call the following URL:
https://api.dataforseo.com/v3/content_analysis/summary/live
[
{
"keyword": "logitech",
"internal_list_limit": 3
}
]
In the response from our API, you will get a comprehensive summary of the target keyword citations, including the overall sentiment distribution by polarity and sentiment connotations, which you’ll need to build this chart.

Sentiment Over Time
By plotting sentiment polarity distribution over a timeline, you can help users see when their brand reputation started deteriorating or improving.
Filling this line graph with data is pretty straightforward. You’ll need to call the Phrase Trends endpoint of Content Analysis API and indicate the desired keyword, date range, and time range which will be used to group the results (by day, week, or month).
Example request:
[
{
"keyword": "logitech",
"search_mode": "as_is",
"date_from": "2022-09-01",
"date_group": "month"
}
]
The results you will get in the response will contain the requested stats for web mentions. The stats will be grouped by a certain date. You’ll need to use data on the number of mentions from the sentiment_connotations and/or connotation_types objects and relevant dates to build the Sentiment Over Time feature.

Sentiment Over Time By Category
Similarly to the feature above, this visualization will plot the sentiment polarity over time, but it will provide a broader view by categories.
Unlike the previous feature, this line graph will come in handy for larger research purposes, such as investigating market trends.
To implement this view, you’ll need to call the Category Trends endpoint and define the necessary category, date range, and time range for grouping (by day, week, or month).
For each category section, make a new API call with the relevant category code.
You can obtain the full list of available category codes and review category names by using the free Categories endpoint.
Here are example requests to obtain trends data for two categories:
[
{
"category_code": 10994,
"search_mode": "as_is",
"date_from": "2022-09-01",
"date_group": "month"
}
]
[
{
"category_code": 10937,
"search_mode": "as_is",
"date_from": "2022-09-01",
"date_group": "month"
}
]
Once you receive the results in the response, you should utilize data from the sentiment_connotations and/or connotation_types objects along with relevant dates to create this graph. To indicate the name of the relevant category, you can use data from the free Categories endpoint.

Sentiment By Rating
This feature illustrates the sentiment polarity distribution according to rating scores.
Relying on this information, users can see how the amount of negative sentiment correlates with a lower rating and the amount of positive sentiment – with a higher rating. They can also get some clues for future investigation about the mentions with positive sentiment and low-rating, and vice versa.
To produce this feature, use the Rating Distribution endpoint of Content Analysis API. Once you define a keyword, make a call to the following endpoint:
https://api.dataforseo.com/v3/content_analysis/rating_distribution/live
[
{
"keyword": "logitech",
"search_mode": "as_is",
"internal_list_limit": 3
}
]
The API response will contain citation stats grouped within a set of two rating scores (min and max) that differ by 0.1. To build a graph like the one on our sketch, use the connotation_types object with the distribution of citations by polarity for each rating score interval.

We hope that this quick overview gave you a few practical development tips. As you can see, when you have the right technologies at hand, assembling a basic dashboard for sentiment analysis of web mentions is not as complex as it might seem.

Wrap up
In a nutshell, sentiment analysis is based on determining whether a text is positive, negative, or neutral. With the advances in technology, ML and NLP in particular, sentiment analysis now allows companies to get meaningful insights from large volumes of data.
While developing a sentiment analysis system in-house is an incredibly elaborate process, companies usually opt for licensing ready-made technologies, such as APIs.
At DataForSEO, we’re offering a multilingual (70+ lang.) Content Analysis API that will help you collect brand or keyword mentions from across the web, automatically score their sentiment polarity, and capture more advanced emotions, such as love, happiness, or anger.
Don’t miss an opportunity to understand your brand’s online reputation and tweak it on time – try Content Analysis API.
