How Can SEO Drive Traffic and Reduce Marketing Risk?

SEO seeks visibility in search results through long-term improvements to a website, its content, and its keyword targeting, giving searchers a chance to visit the site. If this adds search as a traffic source, it may reduce the risk of relying too heavily on a single social platform. However, gaining traffic does not mean gaining conversions, and adding channels does not mean eliminating risk. The supplied material supports a conditional approach, not guarantees of free traffic, rankings, or any particular reduction in advertising costs.

Search traffic comes from website improvements, not just buying exposure

A course promotion post on PTT describes SEO as the long-term work of maintaining and improving a website so that search engines consider it worth recommending on a particular topic, helping it compete for more prominent rankings. This explains a path to attracting traffic, but it is not a promise that optimization will necessarily result in high rankings.

An awoo article from 2016 emphasizes that SEO is closely tied to website development technology and should not be treated simply as another form of advertising. Together with the areas for review outlined in its 2007 article, this work includes:

• Choosing keywords that fit the website’s goals.
• Checking for obstacles search engines encounter when crawling the website and identifying issues to fix.
• Continually improving the website rather than focusing only on buying exposure.

Reducing dependence on a single platform is the starting point for managing risk

Using Facebook as an example, the PTT promotional post argues that search traffic can help spread the risk of relying too heavily on a fan page when algorithms change. The useful underlying logic is that if a website no longer depends on just one platform to bring in visitors, it may become less dependent on that platform. This does not mean SEO can prevent platforms from changing.

The post also claims that SEO can increase traffic for free and save advertising costs over the long term, but it provides no cost or performance data. A more cautious interpretation is that search can become an additional source of traffic. Whether it actually saves money cannot be determined from this promotional post alone, and long-term website improvements should certainly not be understood as requiring no investment.

The wrong keywords can bring traffic without delivering much value

awoo’s 2007 article states that keyword targeting needs to consider the difficulty of competing, the relationship between traffic and conversions, and searchers’ mindsets. Unsuitable choices may affect marketing return on investment. This reflects practical advice from that time, not current official rules from search platforms.

For example, when evaluating a keyword, the question is not only “How many people could it bring in?” but also “What do people searching for this term expect to find?” Following this reasoning, traffic volume is only one part of the assessment. Visitor numbers alone cannot establish that marketing risk has decreased.

Testing recommendations still come with conditions in the changing search landscape

In a 2025 article, SearchPilot’s Will Critchlow recommends incorporating generative engine optimization (GEO) testing into SEO testing programs as traffic from large language models grows, with the aim of reducing uncertainty and finding a competitive advantage. This recommendation comes in a product-promotional context, and the supplied material does not present experimental results. It can therefore serve only as a conditional direction for evaluation, not as grounds for claiming that adopting GEO will necessarily reduce risk.
