GLOBAL CRISES IMPACTING SEARCH ENGINE OPTIMIZATION (SEO) MARKET: IMPACT OF COVID-19 PANDEMIC

SEO Emerged as a Strategic Lifeline Amid Digital Transformation and Changing Consumer Behavior

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The Search Engine Optimization (SEO) Market Share was deeply disturbed by the COVID-19 pandemic, which in turn set forth a change of gears in prioritizing digital transformation for businesses worldwide. As restrictions were enforced to close stores and halt physical interactions, businesses strenuously worked on their own digital transformation to engage their customers and keep the business alive. Thus began a big shift, with SEO increasingly being viewed as a cost-efficient, long-term strategy for online visibility and drawing organic traffic within a time of economic uncertainty.

The lockdown brought about changes in consumer behavior, and these changes reflected search trends. People increasingly searched for essential services, health matters, remote work tools, and e-commerce options. Hence, businesses needed to quickly pivot SEO strategies in light of new keywords that were timely to the topics and relevant to actual intent behind user searches. Relevance and empathy became the go-to focus for brands in crafting information-rich content that can sustain a relationship with their audience.

And following the pandemic, small and medium businesses would have looked for cost-efficient ways of marketing themselves digitally. In an economic slump, few companies reduce their marketing expenses because of cash straits. However, a handful were virtually forced into increasing their SEO budget just to keep on having visibility in a heavily digitized market. Hence, COVID-19 has just laid bare the importance of SEO in developing digital resilience. It made the companies realize that organic search-they used to consider it as just another marketing channel-shifted now to a matter of strategic importance for sustainable growth.

LATEST TRENDS

AI-driven answers reduce site clicks, prompting a transformation in SEO strategies.

There is one significant recent market trend that actually considers a shift in the landscape: the rise of Answer Engine Optimization or Generative Engine Optimization. AEO/GEO is all about modifying content to show in answer engines powered by AI, such as ChatGPT Search, Google’s AI Overviews (AIO), Gemini, and Perplexity, not ranking into traditional search by links. Conversational AIs or interfaces deliver answers directly with little or no user engagement by clicking through the sites. A Business Insider story recently explained that AEO places content in AI-generated answers and favors well-structured question-oriented content addressing clusters of related questions.

SEO will change from optimizing for search engines to optimizing for answer and generative engines, forcing brands to create content that is not just keyword filled but has enough authority, meaning, and machine-readable structures. This rotation will become a bedrock for digital marketing strategy in 2025 and beyond.
