SEO against Paid search, dimension by dimension.
| Dimension | SEO | Paid search |
|---|---|---|
| Time to first result | Months | Days |
| Cost behaviour as you scale | Marginal cost falls | Marginal cost rises as you bid into less qualified demand |
| What happens when you stop | Decays slowly | Stops immediately |
| Testing speed | Slow — weeks per iteration | Fast — the fastest message-testing instrument you have |
| Control over targeting | Indirect, through relevance | Direct, within platform limits |
| Main failure mode | Publishing volume against intent nobody has | Optimising toward a proxy signal instead of revenue |
Which one your situation calls for.
Choose SEO when
- You are building a durable channel and can wait two or three quarters to see it work.
- Your category has genuine informational demand you can answer better than anyone currently does.
- Paid costs in your category have risen to the point where the unit economics no longer work.
The wrong reason: Choosing SEO because it is "free". It is not free; it is prepaid, in content and engineering time, and the invoice arrives before the traffic does.
Choose Paid search when
- You have a launch, a season, or a hiring commitment that needs demand now.
- You do not yet know which message or segment converts, and need to find out quickly.
- Your category is small enough that organic volume would never reach a useful level.
The wrong reason: Choosing paid because it is measurable. Platform-reported conversions include modelled data and default to attribution settings that flatter the channel — measurability and accuracy are not the same thing.

Search engine optimization (SEO)
Search engine optimization is the practice of making a site easier for search engines to crawl, index, understand and rank, so that pages appear for queries the business can actually serve. It covers technical access, information architecture, content quality, internal linking, authority signals and the measurement that tells you which of those moved.
DefinitionCore Web Vitals
Core Web Vitals are Google’s three user-experience metrics: Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness) and Cumulative Layout Shift (visual stability). They are a confirmed ranking signal, and independent analysis indicates they act as a tie-breaker among comparable pages rather than a primary driver.
DefinitionMulti-touch attribution (MTA)
Multi-touch attribution distributes credit for a conversion across the marketing touchpoints that preceded it, using a rule (first touch, last touch, linear, time decay) or a data-driven model. It describes observed sequence; it does not establish that any touchpoint caused the outcome.
