Pinterest Ads Best Practices: What Actually Moves the Numbers

People use Pinterest to plan: a kitchen renovation, a wedding, outfits for a season, recipes for the week. They search, save ideas to boards and return later. That makes the platform closer to a visual search engine than a social feed, and ads that fit into a planning journey tend to perform best.

It also means seasonality starts early. Many users begin planning for holidays and events weeks or months ahead. Pinterest publishes its own seasonal planning guides, and they consistently recommend starting campaigns earlier than advertisers expect.

Install the Pinterest tag on your site with the base code on every page and event codes for key actions: page visit, view category, add to cart, checkout and lead. Shopify, WooCommerce and BigCommerce have official integrations that install the tag and send events automatically.

Add the Conversions API to send server-side events. This improves match rates when browser tracking is blocked. In Ads Manager, open Conversions and check the event history to confirm that events arrive and deduplicate properly.

• Base tag on all pages, event codes on key actions
• Conversions API connected and deduplicated with event IDs
• Enhanced match enabled, sending hashed email where you collect it
• Verified domain and claimed website in business settings

Pinterest offers keyword targeting, interest targeting, demographics, and audiences built from your own data: customer lists, site visitors, people who engaged with your Pins, and actalikes (Pinterest’s term for lookalike audiences). Its automated targeting can also expand delivery beyond your selections.

Keywords are the feature most advertisers underuse. Because people search on Pinterest, keyword targeting lets you appear in search results for planning terms. Build keyword groups around themes, such as “small balcony ideas”, “balcony furniture” and “outdoor lighting”, rather than mixing everything into one ad group.

A starting structure

• Ad group 1: keyword targeting around core product themes
• Ad group 2: interest targeting for broader discovery
• Ad group 3: retargeting site visitors and Pin engagers from the last 30 to 60 days
• Ad group 4: actalike audience based on purchasers

Pins are vertical. The recommended aspect ratio for standard images is 2:3, for example 1000 by 1500 pixels. Videos can run in 2:3, 9:16 or square, but vertical formats take more space in the feed. Keep important text and logos away from the bottom edge, where interface elements may cover them.

Good Pins look like ideas, not adverts. Show the product in use, in a setting the viewer can imagine, and add a short text overlay that explains the benefit. Clear, bright images usually perform better than dark, cluttered ones. Include your brand subtly; a small logo is enough.

• Use 2:3 images or vertical video with captions
• Add a text overlay with a clear idea, such as “3 ways to style a small balcony”
• Write keyword-rich Pin titles and descriptions, since they help both search and ads
• Rotate several creatives per ad group and refresh them every few weeks

For ecommerce, yes. Upload a product catalogue through Catalogs in Ads Manager, either as a data source file or through a platform integration. Pinterest then creates product Pins and lets you run shopping campaigns, including dynamic retargeting that shows people the products they viewed.

Keep the catalogue clean. Product titles should be descriptive, images should be high quality and consistent, and prices and availability must match your site. Group products into sets by category or margin so you can bid differently on each group.

Pinterest offers automatic bidding, where the system aims to get the most results within the budget, and custom bidding, where you set a target cost. Automatic bidding is a sensible start. Switch to a custom target once you have stable conversion data and know your acceptable cost per result.

Give campaigns time. Conversion campaigns need enough weekly conversion events to learn. As an illustrative example, a home decor shop with a target cost per purchase of 25 USD might set a daily budget of around 50 to 75 USD per conversion ad group, then review after two weeks instead of adjusting daily.

Because people save Pins and buy later, short attribution windows undervalue the platform. Pinterest’s default reporting uses longer windows than many social networks, with separate click, engagement and view windows. Compare results under different windows and decide which one you will use for reporting.

Use Pinterest’s conversion insights and, for larger budgets, its conversion lift studies. Also compare your own analytics and store data with platform reports, and track assisted conversions in Google Analytics 4 to see Pinterest’s role earlier in the journey.

What mistakes should you avoid?

Several habits weaken Pinterest results. Running horizontal images taken from other platforms is one; they appear small and lose attention. Changing targeting and bids every few days during the learning period is another, because the system cannot settle. Judging campaigns only on last-click data in Google Analytics undervalues a platform where people save ideas and return later.

Another frequent error is ignoring organic Pins. Promoted Pins that perform well organically often perform well as ads, and organic data is free. Review your top organic Pins in Pinterest Analytics every month and test the best ones as ads.

• Avoid horizontal creative copied from other channels
• Avoid frequent edits during the learning phase
• Avoid judging results on click-only attribution
• Use top organic Pins as a source of ad ideas

Plan seasonal campaigns ahead

Build seasonal campaigns several weeks before the event, so they have time to learn while planning searches are rising. A campaign launched the week before a holiday often misses the period when most people were saving ideas.
