01What Are Claude Code Mods and How Do They Work?

Claude Code mods are a free upgrade that lets you customize Claude Code in plain English. They act like plugins or modifications that change how Claude behaves. You can add new screens, change existing ones, or make Claude step in before certain actions.

Think of a mod as a trigger-based customization. If you keep doing the same SEO tasks, a mod can automate the checks and visual feedback. Julian Goldie explains that mods are different from skills or MCP servers because they respond to actions inside Claude Code.

For example, you can build a mod that shows a token meter on the side, measuring your context window. Calling it with a forward slash command, like /tokens, displays the info whenever you need it. This makes mods simple to use and very flexible.

02Main Features of Claude Code Mods for SEO

  • Customizable commands: Create your own forward slash commands to trigger mods anytime.
  • Visual panels: Build side panels that show checklists, previews, or other data while Claude works.
  • Trigger-based actions: Set mods to act when you perform certain tasks, like writing content or deploying updates.
  • Experience points: Mods can level up over time, changing appearance and improving as you use them more.
  • You can enable mods per session or make them permanent, giving you control over what runs.

Julian also mentions that mods can be used for fun, like creating a Tamagotchi-style buddy that evolves. But for SEO, the key features are the scorecard and the Google preview strip, which give instant feedback.

03How to Set Up Your First SEO Mod

  1. Open Claude Code and ensure you have the latest version that supports mods.
  2. Ask Claude for ideas: say something like, "Give me three visual SEO mods I can build."
  3. Pick one, such as the on-page scorecard, and tell Claude to build it.
  4. Review the code and explanation Claude provides.
  5. Choose whether to enable the mod for this session only or make it permanent.
  6. Run the mod by using its forward slash command or by triggering it with a specific action.
  7. Test it inside one conversation first before deciding to keep it long-term.

Julian recommends testing mods in a single conversation first. This way, you avoid cluttering Claude Code with mods you don't actually use.

04Using the SEO Scorecard Mod Step by Step

After setting up the SEO scorecard, it appears as a side panel. When Claude writes an article, the checklist starts ticking off items automatically. For example, "keyword in title" gets a tick, then "keyword in heading," then "keyword in first 100 words." You can fully customize the checklist to match your own SEO criteria.

In the episode, Julian shows how the scorecard missed the word count target. So he simply asks Claude to add more sections to the content to reach the desired length. That’s all it takes to adjust the output.

There’s also a command called SEO-target that lets you change the target keyword. You type the command, insert the new keyword, and Claude runs through the checklist again. This makes it easy to reuse the mod for multiple pieces of content.

05Building and Using the Google Preview Strip Mod

The Google preview strip is another SEO mod from the episode. When you run it, Claude creates a visual strip that shows how your page will look in search results. It includes the meta title and meta description as they will appear.

Julian uses it to see if the title fits and checks the meta description length. The mod even provides a checklist for best practices. You can test it with a sample keyword to see the preview before publishing.

Because the command is ready at any time, you can call it whenever you need a quick preview. This removes guesswork and helps you craft better meta tags for SEO.

06When to Use Mods vs Skills vs MCP Servers

Julian clarifies the difference. If you keep pasting the same prompt into the chat, you don’t need a mod. Instead, save a skill to Claude.

Skills are for repetitive prompts that you run manually.

If you want Claude to use another app, tool, or service, then you need an MCP server. That connects Claude to external systems.

But mods are for actions that happen automatically based on triggers inside Claude. For example, when you write content, the scorecard appears. That’s the best use case for mods.

07Tips, Limits, and Mistakes to Avoid with Mods

  • Always test a mod in one session before making it permanent. You don’t want unused mods cluttering your setup.
  • Mods can be changed step by step, so don’t be afraid to tweak them to fit your exact workflow.
  • Remember that mods work based on triggers. If you need a manual repetition, a skill might be better.
  • Don’t rely on mods for external integrations—use MCP servers for that.
  • Watch for word count issues; the scorecard example shows how easy it is to miss targets, but you can fix it quickly.

By following these tips, you can avoid common mistakes and get the most out of Claude Code mods.

08Who Should Use Claude Code Mods and Why It Matters

Anyone who uses Claude Code for SEO can benefit from mods. Whether you’re a content writer, SEO specialist, or developer, mods add a layer of automation and visual feedback. Julian says they can make Claude Code “100 times more powerful” for SEO.

They matter because they speed up your workflow. Instead of manually checking on-page factors, the AI does it for you in real time. You see exactly what is done and what’s missing.

Mods also make the process fun and interactive. With experience points and evolving visuals, you stay engaged while working. This can help you create better content consistently.
