# Best Practices

## Recommended setup

<table data-card-size="large" data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>Start with Posts, then layer in Comments</strong></td><td>The Posts entity gives you a complete content inventory including comment counts. Only pull the Comments entity separately when you need the actual comment text or author details — it keeps your data flow lighter.</td></tr><tr><td><strong>Use one data flow per blog</strong></td><td>Each Blog ID maps to a single blog. If you manage multiple blogs, create separate data flows for each and use Coupler.io's Append transformation to merge them into one unified dataset in your destination.</td></tr><tr><td><strong>Send post content to AI destinations for analysis</strong></td><td>Blogger post content comes through as raw HTML. Sending it to Claude, ChatGPT, or Gemini via Coupler.io lets you extract plain text summaries, generate SEO metadata, or classify posts by topic automatically.</td></tr></tbody></table>

## Data refresh and scheduling

<table data-card-size="large" data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>Match refresh frequency to your publishing cadence</strong></td><td>If you publish a few times a week, a daily refresh is more than sufficient. Blogger data doesn't change by the minute — syncing hourly on a low-activity blog wastes API quota unnecessarily.</td></tr><tr><td><strong>Watch your Google Cloud API quota</strong></td><td>The Blogger API allows 10,000 requests per day by default. High-frequency refreshes across multiple entities and multiple blogs can add up fast. Monitor your usage in Google Cloud Console and request a quota increase if needed.</td></tr></tbody></table>

## Performance optimization

<table data-card-size="large" data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>Don't pull all entities at once if you only need one</strong></td><td>Each entity (Posts, Comments, Pages, etc.) is a separate API call. Only add the entities you actually need to your data flow — pulling Users and Blogs metadata repeatedly when it rarely changes is an easy way to burn quota.</td></tr><tr><td><strong>Use Aggregate to summarize comment data before loading</strong></td><td>If you're tracking comment volume over time, use Coupler.io's Aggregate transformation to count comments by post or by date before loading into your destination — this keeps your sheet or table clean without needing formulas on the other end.</td></tr></tbody></table>

## Common pitfalls

{% hint style="danger" %}
Don't confuse your Blog ID with your blog's URL or custom domain. The Blog ID is a numeric string only — using the wrong value will cause the data flow to fail silently or return a "not found" error.
{% endhint %}

{% columns %}
{% column %}

#### Do

* Use the numeric Blog ID from Blogger Settings or the dashboard URL
* Keep your Google Cloud API key unrestricted or scoped to Blogger API only
* Use Append to combine posts from multiple blogs into one destination table
* Pull Comments separately when you need commenter details, not just counts
  {% endcolumn %}

{% column %}

#### Don't

* Use your blog's custom domain or Blogspot URL as the Blog ID
* Apply HTTP referrer restrictions to your API key without accounting for Coupler.io's requests
* Pull all five entities every hour when most of them (Users, Blogs, Pages) rarely change
* Expect draft or scheduled posts to appear — the API only returns published content
