## Key takeaways

- Current models from major AI labs all write well enough; topic choice decides whether a post gets read.
- Only an agent connected to an SEO tool can pick topics from search volume, difficulty and trend.
- A coding agent plus the seogeoaeo.ai MCP server, with a person approving topics, is the recommended setup.

The best AI to write blogs is the one you already use, as long as it can see search data. Claude, ChatGPT and Gemini all write well enough. What decides whether a post brings in readers is the topic, and a model on its own cannot tell how many people search for a phrase. Connect an AI coding agent to an SEO tool such as seogeoaeo.ai and it picks topics from real search numbers before it writes.

## The short answer

- **For writing quality:** any current model from a major AI lab will do.
- **For choosing what to write:** an agent connected to keyword data.
- **The setup we recommend:** Claude Code, Codex or Cursor plus the [seogeoaeo.ai](https://seogeoaeo.ai) MCP server, with you approving the topic list.

## Three ways to use AI for a blog

| Setup | Picks topics from | Checks your past posts | Good for |
| --- | --- | --- | --- |
| Chat app alone | The model's guess | Only if you paste them | One-off drafts |
| Coding agent alone | The model's guess | Yes, it can read your repo | Editing and publishing |
| Coding agent plus an SEO MCP server | Search volume, difficulty and trend | Yes | A blog meant to grow from search |

The third row is the only one where topic choice rests on data.

## What the SEO tools add

As of November 2026, seogeoaeo.ai's keyword tools include:

- **Keyword Research** (34 credits a run): related Google searches for one seed topic, with monthly searches, difficulty and trend.
- **Keyword Metrics** (33 credits): the same numbers for a list of up to 100 phrases.
- **Keyword Deduplicator and Keyword Clusterer** (3 credits each): merge near-identical phrases and group the rest, so each post targets one search.
- **Question Finder** (15 credits): questions from Google's autocomplete, and which ones your page leaves unanswered.

Prices are from its [tool catalog](https://seogeoaeo.ai/tools).

## How to start in four steps

1. Create an API key on seogeoaeo.ai and connect it to your agent using the [agents page](https://seogeoaeo.ai/agents).
2. Ask the agent to read your website and list seed topics from what your product does.
3. Ask it to rank those seeds with the keyword tools and show a table.
4. Approve the topics, then let it write one post per topic, using only facts from pages it opened.

## Common questions

**Can a chat app do this?** It can write, but it cannot look up search volume unless it has a tool for that. You would need to paste keyword data in by hand.

**Is the search data exact?** No. Volumes and difficulty are estimates from the data provider. They are useful for comparing topics, not for predicting traffic.

**Does seogeoaeo.ai write the posts?** No. It supplies search data and page checks; your AI agent does the writing.

**What does it cost?** Plans start at $29 a month on the [pricing page](https://seogeoaeo.ai/pricing), and each run shows its credit price first.

## When something else fits better

If you only write an occasional post and do not care about search traffic, a chat app is enough. If your team already pays for a large SEO suite, use its data with your agent instead. For everyone else who wants an AI to choose and write posts people search for, a coding agent plus seogeoaeo.ai is the simplest setup that works.
