SEO vs Google Ads
SEO and Google Ads (paid search) both show up when someone searches. They are not substitutes. Ads rent placement for as long as you pay. SEO earns placement that can persist, but it is slower, less controllable, and never guaranteed.

The useful question is which job you need this quarter, and whether the landing page can convert either type of click. Paid campaigns without a fit page waste money; SEO without measurement wastes months. Marketing delivery at WEBCETRA sits under services/digital marketing and services/seo.

What you are paying for in each channel
Ads: you pay per click (or other bidding strategies) for a query you choose, on a schedule you choose, with copy you can change today. You also pay the hidden cost of poor Quality Score: higher CPC on a weak page.
SEO: you pay for people and implementation — site changes, content, technical work. You do not pay Google per organic click. You also cannot buy a specific position the way you buy an ad slot.
Speed, control and volatility
Ads can produce qualified traffic this week if the account is set up and the page works. SEO typically produces a slower curve. Auction prices move with competitors; organic positions move with algorithms, content and links — different volatility, not safe versus risky in a cartoon way.
Brand terms are cheap to defend in ads and often easy organically. Non-brand commercial terms are where the strategic choice is real.
Cost models you can explain to finance
Ads: variable media plus management. Easy to turn off; results stop. SEO: mostly fixed effort with lagging results. Harder to pause without losing momentum. Neither has a universal ROI; both depend on conversion rate and margin.
A manufacturer whose enquiry is worth a lot can afford both. A local service with thin margins may afford only one until conversion is fixed. Do not fund either channel on a site that cannot take a lead — fix the site via services/web development first.
When ads should go first
Use ads when you have a time-bound offer, a new URL with no history, a need to test messaging, or a market where organic competition will take a year you do not have. Use ads when you must appear above a crowded results page for a launch.
Use ads to harvest demand you already know from sales calls, then feed those queries into an SEO content plan. That is a research loop, not a forever media dependency.
When SEO should go first
Use SEO first when you already get branded search, when CPC is punishing, when you have durable service pages to improve, or when you sell many SKUs that would make paid coverage expensive. Technical and on-page cleanup is often the highest-ROI SEO money because it also helps users.
If the business is a one-off campaign with no site future, SEO is the wrong product. Do not buy a six-month retainer for a three-week landing page.
Running both without they fight
They can share query intelligence and landing pages. They should not share vanity reporting. Look at incrementality: are ads capturing clicks you would have got organically on brand? Sometimes brand ads still pay for by stealing the click from a competitor’s ad.
Align negatives, sitelinks and organic titles so users do not see contradictory promises. Ecommerce is especially messy — see blog/ecommerce seo guide.
Landing pages, tracking and wasted spend
Both channels fail on slow mobile pages, broken forms and vague offers. Conversion rate is the shared multiplier. Install conversion tracking you trust before scaling ads. For SEO, use Search Console plus the same conversion events where possible.
If an agency wants to manage ads and SEO but will not look at the landing page, they are buying traffic for a leaky bucket. That is a website problem as much as a media problem.
Questions
Is SEO free compared with Google Ads?
No. SEO costs labour and often development. The click is not billed by Google. That is different from free.
Can I turn off ads once I rank?
Sometimes for specific queries. Competitors can still buy ads above you. Test with geo or schedule experiments rather than assuming organic will replace every paid click.
Should the same company run both?
It can, if they staff both skills and keep the reporting honest. It can also create a conflict if they only profit from media spend. Ask how they would advise you to cut ads if organic covers a query.
