SEO, SEM and CRO - What is Digital Marketing Strategy?

SEO (Search Engine Optimization) aims to move websites to the top ranks in search engines organically. It is the foundation of creating sustainable traffic without advertising budget and is one of the channels with the strongest return on investment in the long term.

Concrete example: If an e-commerce site invests in technical SEO, content optimization and backlink strategy for two years, it can reduce its advertising budget by 40%. Because organic traffic starts to feed itself.

Measurement method: Organic traffic increase, keyword ranking and conversion rate should be examined together.

Advantages:
Provides permanent traffic and brand trust in the long term. When content compatible with user intent is produced, conversion rates naturally increase.

Disadvantages:
Results take time. SEO errors or unplanned changes can quickly pull rankings back. Therefore, every site update should be tested according to the SEO plan.

SEM (Search Engine Marketing) provides quick visibility through advertising in search results. Its difference from SEO is that results can be obtained immediately. However, when the budget stops, visibility also stops.

Concrete example: In a new product launch, quick access to the target audience can be provided with Google Ads campaigns. During the same period, SEO content is prepared so that brand visibility is maintained even if the campaign ends.

Measurement method: Cost per click (CPC), ad conversion rate and customer acquisition cost (CAC) metrics should be tracked.

Advantages:
Gives quick results, ideal for strategic tests. Target audience segmentation can be done and ad texts can be shaped according to user intent.

Disadvantages:
Not sustainable. When payments are not made for clicks, traffic is lost. Therefore, SEM should be supported with permanent SEO strategies.

CRO (Conversion Rate Optimization) aims to convert more of the visitors coming to the website into customers. SEO and SEM bring traffic. CRO converts traffic into revenue.

Concrete example: A business can increase its conversion rate by 25% by improving page loading speed by 2 seconds and testing CTA (Call-to-Action) button color.

Measurement method: A/B tests, user session analysis and funnel (conversion funnel) tracking metrics.

Advantages:
Can be applied without coding knowledge. Even small changes can dramatically increase conversion performance.

Disadvantages:
Conversion optimization is not only technical but also a psychological skill. User behavior, content language and trust elements need to be analyzed together.

SEO, SEM and CRO are complementary systems. SEO provides organic visibility in the long term, SEM provides speed in the short term, and CRO converts all traffic into revenue.

Benefits of balanced use:

• Advertising costs decrease over time
• Organic traffic becomes permanent
• Conversion rate increases
• Brand trust increases
• Data-driven growth is achieved

Application example:
A business that only invests in advertising can spend 400,000 TL in two years. A business that uses SEO, SEM and CRO holistically in the same period spends 250,000 TL and makes the same traffic permanent. Moreover, despite reducing the advertising budget at the end of the second year, visibility continues.

1. Automate SEO Strategy

• Create weekly performance reports using Google Search Console, Ahrefs or SEMrush.
