What is MJ12bot?

SEO Crawler bot

What MJ12bot means for your site

MJ12bot crawls your site to collect data for an SEO analytics platform. This data powers backlink analysis, keyword tracking, and competitive intelligence tools used by SEO professionals. It does not affect your search rankings or site performance in any meaningful way. Its presence simply means your site is being analyzed as part of the broader web.

What should you do?

  • Allow MJ12bot unless crawl rate is excessive
  • Set a crawl-delay in robots.txt if server load is a concern
  • No SEO action needed, this bot is informational only

How to identify MJ12bot

MJ12bot uses the user-agent "MJ12bot" and robots.txt compliance unconfirmed. It is one of the most active non-search crawlers on the web.

How to block MJ12bot

Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known MJ12bot user-agent pattern so the rules apply regardless of which one the bot announces. Compliance with robots.txt is unconfirmed for MJ12bot, so verify with crawl logs after deploying.

Edit robots.txt with care

A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just MJ12bot, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to MJ12bot's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.

Option 1: Block all access

Tells MJ12bot not to crawl any URL on your site. Use this when you want the bot completely off your content.

User-agent: MJ12bot
User-agent: mj12bot
Disallow: /

Option 2: Block specific paths only

Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.

User-agent: MJ12bot
User-agent: mj12bot
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/

Option 3: Slow down with a crawl delay

Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when MJ12bot is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

User-agent: MJ12bot
User-agent: mj12bot
Crawl-delay: 10

Frequently Asked Questions

What is the User-Agent for MJ12bot?

MJ12bot identifies itself with the User-Agent string "MJ12bot" (alternate forms: mj12bot). Use this in robots.txt or firewall rules.

Does MJ12bot affect my Google rankings?

No. MJ12bot collects data for an SEO analytics platform, separate from any search engine's ranking algorithm. Allowing or blocking it has zero SEO impact on Google, Bing, or other search engines.

Should I block MJ12bot?

Usually not. Blocking only prevents your site from appearing in this tool's backlink and SEO database, which means competitors who use the tool cannot analyze your site. Some site owners prefer this for privacy. Most have no reason to block.

How do I block MJ12bot if I want to?

Try robots.txt first ("User-agent: MJ12bot / Disallow: /") and verify with crawl logs that the bot stops appearing.

Why is MJ12bot crawling my site so frequently?

SEO tools tend to re-crawl popular sites often to keep their backlink and ranking data fresh. If the load is excessive, set a Crawl-delay directive in robots.txt: "User-agent: MJ12bot / Crawl-delay: 10" — most respect this.

Is data MJ12bot collects shared with my competitors?

This tool's customers can typically see basic crawl data about any indexed site (backlinks, top pages, keyword visibility). If you do not want this exposed, blocking is the only way to opt out.
