Measuring "Share of Search": The Brand Metric That Actually Matters Now

Why Share of Search Matters in the Zero-Click Era

Marketers have long used website traffic, clicks, and conversions to gauge the success of marketing campaigns. Yet, how people discover and consume information is changing. Today, potential customers may interact with a business through AI-generated responses, social media postings, videos, email newsletters, and conversations without ever visiting the brand's website.

Such interactions can raise awareness and interest in the product or service without creating any clicks. Therefore, in addition to other methods, marketers require means to track whether their brands gain visibility.

Share of Search is one such method. Share of Search is an indication of the share of search interest in a particular category by a brand against its competitors. Even though Share of Search alone will not prove any growth in revenue, it can help marketers learn whether their brand gains traction in the market.

In the zero-click world, such a measurement is becoming increasingly relevant.

1. What is Share of Search?

Share of Search gauges the level of search interest in a brand based on a comparison to selected competition among brands within the same category.

The basic equation is as follows:

Share of Search = (Branded Search Volume ÷ Total Search Volume for Selected Brands) × 100%

For instance, when competing brands accumulate 100,000 total branded search volumes during a certain time period, and one of those companies attracts 20,000, then it has a 20% share of search during that measurement period.

To calculate the metric correctly, a marketer should define competitors, relevant branded search terms, and the measurement period. The key to accurate calculation is consistency because otherwise the metric will be hard to compare between periods.

The idea is not to measure the number of search queries, but rather the degree of search interest in a brand compared to its competitors and how it changed over time.

2. Why Share of Search is Becoming More Important

Content that does not require clicks is altering the way consumers engage with brands. For example, an individual could learn about a brand through a LinkedIn post, a video, or an AI-based answer without clicking on any links. The engagement may help build awareness even when there is very little traffic on the website, according to the website's analytics.

The person will eventually search for the company.

This represents a sequence of engagement, from exposure to brand awareness, then search interest, and ultimately commercial consideration. Share of Search allows marketers to gauge the search interest phase of this process.

An increase in branded searches could suggest that there are more people actively searching for the brand after engaging with its content or knowledge. While this does not mean that a specific campaign has been successful, it provides a bigger picture of brand awareness compared to just clicks.

3. Share of Search vs. Website Traffic

Website traffic and Share of Search are two very different marketing performance indicators. Traffic indicates the volume of visitors to the company's websites, whereas Share of Search shows what percentage of search interest a certain company has in the chosen competitive category.

Take a company that experiences a decrease in its organic website traffic because search engines are providing answers without requiring users to click on anything. At the same time, if its Share of Search increases during the same period of time, then it is not necessarily a bad sign. The company might attract more search interest even though there is less traffic.

That is why marketers should use both website analytics and Share of Search and not try to replace one metric with another.

Traffic shows what happens on the company's owned digital channels. Share of Search gives an idea about how well the brand performs in comparison with other brands in the market.

4. How to Measure Share of Search Effectively

The first step in measuring Share of Search involves identifying the competitive category. Competitors should only include brands that buyers see as alternatives. Including unrelated brands can affect the results.

The next step involves identifying the branded search terms that need to be measured. This needs to be done consistently for all selected brands. The measurement period, whether monthly or quarterly, should also be consistent.

After collecting the search data, each brand's share of the total search volume should be calculated. Tracking the results over time will reveal any significant changes in the market's attention.

An increase or decrease in the metric alone does not necessarily mean an improvement or decline in the performance of marketing efforts. This is because search behavior may vary due to seasonality, news, competition, and interest in the category in general.

5. What a Growing Share of Search Can Reveal About Marketers

An increasing Share of Search suggests that the brand gains prominence in the category because of thought leadership, unique content, executive prominence, and repetition.

The buyer may learn about a company's opinion on a matter from a social media post, then find that it shows some expertise on an external website, and finally search for the company after a business need arises. Such search implies that a brand has become memorable enough that buyers look for more details.

It helps marketers understand brand visibility and future demand.

However, one shouldn't treat increased search activity as a clear indicator of future profitability. Increased numbers of searches about a company do not translate into better leads and revenue generated by marketers. Share of Search serves as a measure of market engagement rather than profitability.

The value of it lies in demonstrating whether brand interest is increasing and giving marketers a tool to explore the correlation between such interest and performance.

6. Employing Share of Search along with other brand Signals

Share of Search can be more insightful when combined with other performance metrics. A holistic zero-click measurement approach can relate brand awareness, Share of Search, engagement quality, pipeline, and revenue.

Each metric answers a separate question. Brand awareness tells whether the firm is reaching out to its target audience. Share of Search reveals whether it captures enough search attention compared to the competition. Engagement quality helps understand whether there is an interaction with the content. Pipeline and revenue metrics tell whether all this activity translates into business results.

Brand lift can also add valuable information about changes in awareness, recognition, and consideration.

Combining these metrics will help marketers avoid evaluating the whole strategy based on one metric. For example, if Share of Search grows while there is no increase in pipeline activity, this may mean that awareness increases but the brand fails to attract enough relevant customers.

The goal here is to measure how search demand fits the broader visibility-to-business growth funnel.

7. Make Share of Search a Strategic Marketing Metric

Rather than having Share of Search as something that appears on a dashboard, marketers can use the data to make marketing decisions and see if initiatives such as content creation, thought leadership, and brand campaigns are aligned with changes in search interest.

Also, marketers can compare themselves to their competitors to understand where their brands are becoming more visible or losing ground.

Consistently high Share of Search as a result of continuous efforts to produce unique content will serve as useful evidence that the brand is increasing its market presence.

If there is no change in numbers despite increased content publishing, then marketers have to think about whether their content has become irrelevant or less unique.

The core issue here is not only if the campaign brought clicks but if the brand is becoming more visible and interesting to potential buyers.

This is especially relevant to zero-click marketing because marketers want to create an impression now that will help the buyer look for the company later.

Conclusion: Check If the Market Is Seeking Out Your brand

With the coming of the zero-click era, website traffic and click data have become less reliable indicators of brand performance since buyers can learn about and consume content outside of a company's website.

The Share of Search measure solves this problem by providing an indicator of the share of search visibility obtained by the brand within its market. Combined with brand lift, engagement, pipeline, and revenue metrics, it provides a clearer picture of brand visibility and demand generation.

The purpose is not to discard traffic measures altogether but rather to see what they cannot say alone.

Beyond simply asking, “How many people clicked?” Another important question for marketers is whether more people are actively searching for their brand.

In a zero-click world, it will help us understand whether a company becomes visible, memorable, and relevant enough for buyers to look for it themselves.
