If you’re running a blog or niche site, you’ve probably heard Pinterest is one of the best places to still get traffic for 2025 and into 2026…

Pinterest is not just another social media platform where your content disappears into an endless scroll.

Pinterest is actually a visual discovery engine.

And that distinction? That’s your golden ticket to free, organic traffic that actually converts.

Unlike Instagram or Facebook where posts vanish after a few hours, your Pins keep working for months (sometimes years) pulling in people who are actively searching for ideas, products, and solutions.

But here’s the thing…

With billions of Pins created by hundreds of millions of users, how do you actually cut through the noise?

The answer isn’t guessing or copying what someone else is doing.

It’s understanding the fundamental architecture that powers Pinterest’s recommendations and search results.

How Pinterest’s Algorithm Actually Works: The Pin-Board Graph System

To win on Pinterest, you need to understand how the platform’s brain actually works.

Pinterest sees your content as nodes in a massive network called a “Pin-Board bipartite graph.”

I know that sounds technical, but stick with me…

Here’s what this means in simple terms:

Pins as Nodes: Every Pin you create becomes a point of data that represents your content (image, video, or link).

Boards as Nodes: Every Board you create becomes another point of data that represents a collection of related content.

The Connection: When you save a Pin to a Board, you create a “pathway” between those two points.

This is where it gets interesting…

When someone searches on Pinterest or interacts with content, the algorithm performs what engineers call “random walks” through this network starting from content it knows is relevant.

The Pins and Boards that get visited most frequently during these walks are considered the most similar to what people are looking for.

Think of it like this…

If you’re looking for chocolate chip cookie recipes, Pinterest starts at known cookie recipe Pins and “walks” through the network to find related content.

The Pins that are most strongly connected to cookie-related boards and other cookie Pins will surface first.

Your job is simple: Create clear, undeniable pathways between your content, your boards, and the specific topics people are searching for.

You do this through precision in your keywords and careful curation of your boards.

Pinterest Keyword Research: Speaking the Platform’s Native Language

Pinterest search works differently than Google…

People often use broad, exploratory queries when they’re looking for inspiration, not specific answers.

Someone might search “easy dinner ideas” instead of “how to cook chicken parmesan in 30 minutes.”

This open-ended nature means your keywords must bridge the gap between inspiration and action.

Understanding Pinterest’s Interest Taxonomy

Pinterest organizes all topics into what they call an “Interest Taxonomy” – basically a giant, structured tree of topics and subtopics with around 11,000 official interest nodes.

This taxonomy can have up to 10 or 11 levels of granularity, starting with broad verticals like “Women’s Fashion” and “DIY and Crafts,” then getting incredibly specific.

For example, “Home Decor” might break down into specific classifications like “farmhouse kitchen decor” or “small apartment storage solutions.”

Your goal is to map your content directly to a relevant branch of this tree.

How Pinterest Validates Your Keywords

When you use keywords in your Pin titles, descriptions, and board names, Pinterest tries to map your content to one of these precise Interest Taxonomy nodes.

Pinterest maintains what’s called an “Annotations Dictionary” – basically the official keywords that the system recognizes as high-quality descriptions.

These annotations are short keywords or phrases, usually between one and six words, that clearly describe the Pin’s subject.

The system heavily prefers words that exist in this dictionary because it guarantees the terms will be valid and useful phrases.

This filters out low-value content like generic phrases (“ideas,” “things”), stop words (“the”), fragments (“of liberty”), or common misspellings (“recipies”).

Pinterest also identifies strong topical phrases as “unit groups” – groups of words that are more likely to appear together than separately.

For example, “Cocker Spaniel” is identified as a unit group, and Pins using this specific phrase get related to other content using the same unit group.

Your Complete Pinterest Keyword Research Strategy

Your goal is to align your Pin’s metadata directly with terms found within the Interest Taxonomy and Annotations Dictionary.

But how do you actually find these official keywords?

Step 1: Start with Pinterest Trends

Pinterest Trends is your goldmine for discovering the most popular keywords to target right now.

This free tool shows you what people are actively searching for and engaging with on the platform.

Start by searching broad topics in your niche and look at the trending keywords Pinterest suggests.

These aren’t random suggestions – they’re pulled directly from the Interest Taxonomy.

Step 2: Use Pinterest Trends for Contextual Keywords

Once you find a popular keyword in Pinterest Trends, dig deeper…

Look at the related and contextually relevant keywords Pinterest shows you for each popular term.

These related keywords are perfect for including in your Pin descriptions because they help with better optimization, distribution, and interest matching.

For example, if “easy dinner recipes” is trending, Pinterest Trends might show related terms like “30 minute meals,” “family dinner ideas,” or “weeknight cooking.”

Use these related terms in your Pin descriptions to cast a wider net while staying within the official taxonomy.

Step 3: Find Evergreen Keywords with PinClicks

While Pinterest Trends shows you what’s hot right now, PinClicks helps you find evergreen keywords that drive consistent traffic all year long.

These are the keywords that might not be “trending” but have steady, reliable search volume month after month.

In PinClicks, you can search any keyword and see:

Monthly search volume
Related keywords with their search volumes
The official Pinterest interest categories for each keyword
Top performing pins for those keywords

This data helps you build a content strategy that combines trending topics (for quick wins) with evergreen content (for long-term traffic).

Step 4: Spy on Popular Accounts in Your Niche

Here’s where PinClicks really shines…

The Account Explorer tool lets you type in popular keywords like “recipes” or “home decor” and shows you the most popular Pinterest accounts based on their monthly impressions.

Once you find these top accounts, you can explore and see:

All the keywords they rank for
Their most popular pins and boards
Their top performing blog post links
Which interest categories drive their traffic

This is like getting a behind-the-scenes look at what’s actually working for successful accounts in your space.

Topic Cohesion: The Critical Success Factor

This is probably the most critical concept for getting consistent Pinterest traffic…

Pinterest actively measures something called “topic cohesion” between your Pin and your linked blog post.

If your Pin promises “Healthy Chocolate Strawberry Shake” but your blog post is just a generic “Dessert Recipes” page, that’s a problem.

Pinterest calls this “topic drift” and they actively try to prevent it.

Here’s how Pinterest understands what your content is about:

The platform looks at “text signals” from multiple sources:

Your Pin title and description
Your Board name and description where the Pin is saved
The page title and description of your linked blog post
Search queries that frequently lead to engagement with your Pin

How to Nail Topic Cohesion:

1. Match Your Signals: Make sure your Pin title, description, and image align perfectly with your blog post title, content, and main topic.

2. Be Specific: If your Pin is about a specific recipe, your blog post better be about that exact recipe, not a collection of 20 different recipes.

3. Quality Content: Pinterest reindexes web content daily to measure relevance. Your linked page needs to be high-quality and directly address what your Pin promises.

When you get topic cohesion right, Pinterest promotes your content.

When you get it wrong, they take “remedial actions” (translation: your traffic disappears).

Pinterest Board Strategy: The Foundation of Success

Your boards are like filing cabinets that give context to your Pins…

When you save a Pin to a board, you’re telling Pinterest exactly what that Pin is about through human curation.

The way you structure your boards impacts how the algorithm maps your content for recommendations.

The Danger of Diversity (Critical Algorithm Insight)

Here’s something most Pinterest creators get wrong…

Pinterest analyzes the “cohesiveness” of your boards using something called a “diversity score.”

If a board contains Pins about too many different topics, that board (and all the Pins in it) might get excluded from recommendations entirely.

This is called “Graph Pruning” – basically Pinterest ignoring your content because it’s too scattered.

Your Board Optimization Strategy:

1. Create Hyper-Niche Boards: Instead of a board called “Baking,” create specific boards like “Sourdough Starter Tips for Beginners” or “Gluten-Free Chocolate Chip Cookies.”

This lowers your diversity score and increases the chances Pinterest includes your boards in recommendations.

2. Optimize Board Descriptions: Treat your board titles and descriptions like mini SEO fields. Use your target keywords here to provide strong signals to Pinterest’s indexing system.

For example: If you have a Pin about “Daisy Ridley at the 2016 Academy Awards” saved to a board called “Oscar Gowns,” Pinterest can connect that Pin not just to Daisy Ridley, but to the highly relevant context of “oscar gowns.”

3. Use Sub-Boards When Possible: These allow for deeper organization without compromising board cohesion.

By creating highly cohesive boards, you’re giving the algorithm the clearest possible signals about what your content relates to.

Pinterest Pin Design Strategy: Visual Optimization for the Algorithm

Pinterest is visual-first, which means people make split-second decisions based on what they see…

Your Pin must serve as an irresistible visual bookmark that compels someone to click through to your content.

Pinterest uses computer vision and deep learning to analyze your Pins in real-time.

Creating Algorithm-Friendly Visuals

Pinterest’s visual systems detect objects and features in your images, using them as signals for recommendations.

Visual Similarity vs Semantic Similarity: The platform measures not only if images look the same, but also if they represent the same concept (even if visually different).

Your image should clearly represent your topic, even if it’s abstract.

Clarity is King: If your Pin features a specific object (like a recipe ingredient or piece of furniture), Pinterest’s object detection analyzes that in real-time to serve related results.

Clear, high-quality images increase the chances of accurate detection and relevant exposure.

Pinterest Engagement Metrics That Matter

Pinterest’s ranking model (called “Pinnability”) optimizes for engagement, but not just any engagement…

The signals Pinterest values most include:

Saves (Repins): When someone saves your content to their board, it signals strong interest.

Long Clicks: Pinterest measures “high-quality traffic” – clicks that last 35 seconds or more carry strong positive signals. This means your Pin design succeeded not just in getting the click, but in delivering promised value.

Hides/Dislikes: Users can explicitly hide Pins, giving strong negative signals. Avoid “clickbait” designs that promise one thing but deliver something else.

Pin Design Best Practices:

Text Overlay: Use keyword-rich text that clearly states the benefit, but make sure it matches your article’s actual topic
Test Formats: Experiment with images, videos, and Idea Pins – diverse content formats increase interaction
Monitor Analytics: Pay attention to which designs generate the highest combination of saves and long clicks

Understanding Pinterest Interest Keywords

Interest keywords are the bridge between what people search for and what Pinterest’s algorithm understands.

When someone searches “healthy breakfast ideas,” Pinterest doesn’t just look for those exact words…

It maps that search to related interest nodes like “meal prep,” “clean eating,” “protein recipes,” and “morning routines.”

If your Pin is optimized for the right interest keywords, it can show up for searches you never specifically targeted.

This is why using Pinterest’s official vocabulary is so powerful – you’re speaking the same language as the algorithm.

PinClicks is the only tool that has indexed all 20 million plus interest keywords for you to instantly browse or search through.

Your Complete Pinterest Traffic Action Plan

Getting free organic traffic from Pinterest comes down to becoming indispensable to the visual discovery engine…

You need to communicate your content’s topic and value clearly and consistently across all your assets.

Here’s your step-by-step action plan:

Step 1: Research Official Keywords
