Internal links are easy to forget and tedious to add by hand, yet they help readers and search engines both. So here is an agent that reads a new post and your existing pages and tells you exactly which internal links to add and where.

Table of Contents

What will you build?

An internal linking agent. You give it a new article and a list of your site’s URLs (with titles), and it suggests several relevant internal links: which page to link to, suggested anchor text, and where in the draft it fits. You add the ones you like.

What do you need to start?

A free Gumloop account.
Your new article text.
A list of your site’s URLs and titles (a sitemap export or a sheet works).

How does it work?

It is an agent that compares the new article against your URL list and finds topical matches, then proposes links. It does the matching; you make the final call on each suggestion.

Give the agent your draft and your URL list; it suggests where to link internally.

How do you build it, step by step?

Create a New Agent and paste these instructions:

Given a new article and a list of my site URLs with titles, suggest
5 to 10 relevant internal links. For each, give the target URL,
suggested anchor text, and the sentence in the draft where it fits.
Only suggest links that are clearly relevant.

How do you set the model to Claude?

Open the AI step or agent and pick the model. For careful work I use Claude 4.8 Opus, the “Smartest” option; a faster model saves credits on simple runs.

Gumloop’s model picker: Claude 4.8 Opus is the “Smartest” option, with Gemini, GPT, DeepSeek and more.

How do you run it?

Paste the article and your URL list and run it. Review each suggestion, add the ones that help the reader, and skip the rest. Keep your URL list handy and reuse the agent for every new post.

What can go wrong?

Irrelevant links. The instruction says relevant only. Reject any that feel forced.
Stale URL list. Keep your list current so it does not suggest dead pages.
Over-linking. A handful of strong links beats many weak ones. See the AI Automation hub.

Common questions

Do I need to code it?

No. You write the agent instructions and give it your article and URL list.

Where do I get my URL list?

Export your sitemap or keep a sheet of URLs and titles. The agent reads that list.

Will it add the links for me?

It suggests them with anchor text and placement. You add the ones you approve.

Can it run on every post?

Yes. Reuse it for each new draft, feeding the same URL list.

Does it use Claude?

Yes, if you pick it. Claude 4.8 Opus is the “Smartest” model. See the AI Tools Directory.
