Home / SEO or Google Ads for ecommerce

SEO or Google Ads for your ecommerce store: which to use and when.

Google Ads brings sales while you pay for each click; SEO takes longer to get going, but the traffic it earns keeps coming without paying per visit. The usual answer isn’t to pick one, but to decide what you do first.

When to start with Google Ads.

  • You have just launched the store and need sales and data now.
  • You have a seasonal campaign or a new product.
  • You want to validate which searches convert before investing in content.

One condition: your margin must be able to bear the cost of the click. If each sale costs you more in ads than you earn, that isn’t scale, it’s a loss.

When to start with SEO.

  • You already sell and depend too much on ads.
  • Your margins are tight and the cost per click eats your profit.
  • Your customers search for what you sell on a recurring basis.
  • You also want AI engines to cite you: SEO is the foundation of GEO.

How to combine them.

  • Use Google Ads to discover which terms convert and take them into the SEO plan.
  • If competitors are bidding on your brand, consider protecting your brand searches with ads.
  • When a category already ranks well, reduce ad spend gradually and by measuring, not all at once.
  • Share conversion data between both channels so you decide with sales, not clicks.

How to decide with numbers.

Work out how much an organic visit is worth today (conversion rate times average order value) and compare it with what a paid visit costs you. On the home page there is an indicative calculator; for your real case, the best reference is your own Analytics data.
