Free Online Robots TXT Generator

I won’t lie, Robots.txt scared me in the beginning.

Not because it’s complicated, but because it’s powerful in a silent way. You don’t see instant errors. No red warnings. No drama. And then suddenly—boom—pages vanish from search.

One evening, while checking indexing on a small test site, I noticed something odd. Pages were published, internal links were fine, sitemap was submitted… yet Google wasn’t crawling properly. After two cups of tea and one mild panic attack, I found the culprit.

A single wrong rule in robots.txt.

That’s when I decided on two things:

  1. I’ll never treat robots.txt casually again

  2. I’ll always use a free online robots txt generator instead of typing blindly

This article is everything I’ve learned since then—from mistakes, testing, fixing, and building tools around SEO on Peplio.

Robots.txt explained like I’d explain to a friend

Forget definitions for a moment.

Imagine your website is a factory.

Search engines are inspectors.
Robots.txt is the entry instruction board outside the gate.

It doesn’t say:

It only says:

Search engines like Google, Bing, and others respect this file before crawling.

If you block the wrong door, inspectors never even see your best machine inside.

Why robots.txt becomes critical as your site grows

In early days, people ignore robots.txt. I did too.

But as your site grows:

That’s when search engines start wasting crawl budget.

Robots.txt helps you say:

“Boss, focus here. Ignore that mess.”

And that’s real SEO maturity.

Why I strongly prefer a free online robots txt generator

Let me be very honest here.

Most robots.txt mistakes happen because of copy-paste SEO:

A free online robots txt generator fixes this by design.

From my own experience, a good generator:

That’s exactly why I use Peplio’s tool:

It doesn’t try to sound smart. It tries to keep your SEO safe.

How robots.txt actually works (important but simple)

When a bot visits your site, this is the order:

  1. Bot requests /robots.txt

  2. Bot reads rules matching its user-agent

  3. Bot decides what it can crawl

  4. Only then crawling starts

No robots.txt = free access
Bad robots.txt = SEO suicide
Clean robots.txt = controlled crawling

Common robots.txt directives (in human language)

User-agent

Who the rule is for.

User-agent: *

Means: all bots

Disallow

Where bots should NOT go.

Disallow: /wp-admin/

Allow

Exceptions inside blocked folders.

Allow: /wp-admin/admin-ajax.php

Sitemap

A gift to search engines.

Sitemap: https://example.com/sitemap.xml

Many people forget this. I used to. Never again.

My exact step-by-step process using a free online robots txt generator

This is literally how I do it—no polishing.

Step 1: Think before generating

I ask:

This thinking matters more than the tool.

Step 2: Open the generator

I go straight to:

No login. No popups. No SEO lecture.

Step 3: Start with “Allow all”

I never start by blocking.

User-agent: *
Allow: /

Then I add disallows one by one.

Step 4: Block only what deserves blocking

Typical blocks I use:

Not categories. Not blogs. Not assets.

Step 5: Add sitemap (non-negotiable)

This step alone fixed indexing speed for me multiple times.

Step 6: Generate, review, upload

Upload to:

public_html/robots.txt

Then I always test using Search Console.

Real example: A safe robots.txt for most WordPress sites

User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

Sitemap: https://yourdomain.com/sitemap.xml

Simple. Boring. Effective.

SEO loves boring consistency.

Robots.txt and SEO: where people get confused

Let me clear this once and for all.

Robots.txt does NOT:

Robots.txt DOES:

I learned this distinction the hard way.

Robots.txt vs Noindex vs Canonical (quick clarity)

Tool Purpose Best Use
Robots.txt Control crawling System & junk URLs
Noindex Remove from index Thin/duplicate pages
Canonical Merge signals Similar content

Use the right weapon. Don’t swing blindly.

One mistake I personally made (so you don’t repeat it)

I once blocked:

Disallow: /wp-content/

Result?

Traffic dipped silently.

Lesson learned:
Never block assets unless you truly know why.

A small experiment I ran (real signal)

Two similar blogs. Same content speed.

After 4 weeks:

Nothing fancy. Just discipline.

For deeper understanding, I often cross-check with Google Search Central and crawling tools from Ahrefs—not to copy, but to validate.
