Analyst Opinion

The Search Advertising market is experiencing significant growth worldwide, driven by the increasing reliance on digital platforms for information and the growing popularity of online shopping. As more and more consumers turn to search engines to find products and services, businesses are recognizing the importance of search advertising to reach their target audience effectively.

Customer preferences:
In today's digital age, customers are increasingly using search engines to find information, products, and services. The convenience and accessibility of search engines make them the go-to source for consumers looking for answers or solutions. As a result, businesses are investing heavily in search advertising to ensure their products and services appear prominently in search engine results.

Trends in the market:
One notable trend in the Search Advertising market is the increasing adoption of mobile devices. With the widespread use of smartphones and tablets, consumers can access search engines anytime and anywhere. This shift towards mobile search has led to a surge in mobile advertising, with businesses optimizing their search ads for mobile devices to capture the attention of on-the-go consumers. Another trend is the rise of voice search. With the proliferation of voice-activated virtual assistants like Siri, Alexa, and Google Assistant, more consumers are using voice commands to perform searches. This has prompted businesses to adapt their search advertising strategies to cater to voice search queries, optimizing their ads for voice-activated devices and incorporating conversational keywords.

Local special circumstances:
In certain regions, there may be specific local circumstances that influence the Search Advertising market. For example, in emerging markets, the adoption of digital technologies and internet access may still be growing. This presents both opportunities and challenges for businesses operating in these regions. On one hand, there is a vast untapped market of potential customers who are just starting to embrace digital platforms. On the other hand, businesses may need to invest in infrastructure and education to facilitate the growth of the Search Advertising market.

Underlying macroeconomic factors:
The growth of the Search Advertising market is also influenced by underlying macroeconomic factors. For instance, a strong economy generally leads to increased consumer spending and business investments, which in turn drives the demand for search advertising. On the other hand, during periods of economic downturn, businesses may reduce their advertising budgets, impacting the Search Advertising market. Additionally, regulatory changes and privacy concerns can also impact the Search Advertising market. For example, stricter data protection regulations may limit the targeting capabilities of search ads, requiring businesses to adapt their strategies to comply with new rules. Similarly, consumer privacy concerns may lead to changes in search engine algorithms and ad placement policies, affecting the effectiveness of search advertising campaigns. In conclusion, the Search Advertising market is experiencing significant growth worldwide due to customer preferences for digital platforms, the increasing adoption of mobile devices, the rise of voice search, and the influence of underlying macroeconomic factors. To capitalize on this growth, businesses need to adapt their search advertising strategies to cater to customer preferences, leverage emerging trends, and navigate local special circumstances and regulatory changes.


Data coverage:

Data encompasses enterprises (B2B). Figures are based on search advertising spending and exclude agency commissions, rebates, production costs, and taxes. The market covers search advertising that is displayed on search result pages or next to organic search results.

Modeling approach:

A combined top-down and bottom-up approach determines the market size. Starting with the top-down approach, we calculate global search advertising by aggregating advertising revenues from key players (Alphabet (Google), Microsoft (Bing), Baidu, Amazon, Alibaba, etc.). Followed by the bottom-up approach, we justify global, country, and region results using web traffic and the number of app downloads. Lastly, we distribute the results to each country individually with relevant indicators such as GDP, internet users, and digital consumer spending by country.


We use a variety of forecasting techniques, depending on the behavior of the market. For instance, the S-curve function is well suited to forecast digital products due to the non-linear growth of technology adoption, whereas exponential trend smoothing (ETS) is more suited for projecting steady growth in traditional advertising markets.

Additional notes:

Data is modeled using current exchange rates. The impacts of the COVID-19 pandemic and the Russia-Ukraine war are considered at a country-specific level. The market is updated twice per year in case market dynamics change.
