What is AdsBot, and why is it visiting my website?

AdsBot (commonly AdsBot-Google) is a crawler operated by Google to evaluate landing pages used in Google Ads campaigns. Its primary purpose is to assess page quality, relevance, load performance, and compliance with advertising policies. Visits are triggered by active or recently updated ad campaigns, and crawl behavior is selective rather than site-wide. If you run Google Ads, this bot traffic is expected and necessary for ad delivery and optimization. Visits from AdsBot are non-harmful.

Is AdsBot a legitimate bot, or is it commonly spoofed?

AdsBot is an official Google crawler and is considered legitimate. However, its user-agent can be spoofed by malicious actors attempting to bypass security filters or disguise automated traffic. Attackers may imitate AdsBot because many systems allow Google bot traffic by default. As a result, User-Agent strings alone are not reliable for verifying authenticity in website logs. You can use Google's recommended methods mentioned below to verify a legitimate visit, or use RobotSense.io API to easily verify AdsBot visits.

How can I verify that a request is really coming from AdsBot?

You can use Google's recommended official methods to verify AdsBot visits, these include: - IP range checks - Reverse DNS → forward DNS Do not use User-Agent based detection as that can be easily spoofed. Alternatively, you can use RobotSense.io API to easily verify AdsBot and all other bots from Google.

Should I allow or block AdsBot on my website?

Allowing AdsBot is generally recommended if you use Google Ads, as it directly impacts ad quality evaluation and campaign performance. The crawler helps determine whether your landing pages meet Google’s standards. Blocking may be appropriate if: - You are not running Google Ads campaigns - You want to restrict automated evaluation of landing pages - You are protecting sensitive or non-public content - Your server cannot handle additional bot traffic If you are suddenly seeing too many visits, you can consider adding a small crawl-delay in your robots.txt before completely disallowing.

How can I control or block AdsBot using robots.txt or other methods?

You can add a rule in your robots.txt, as given above to control (crawl-delay) or disallow AdsBot. Also, you can use further controls in your WAF, or in RobotSense enforcement settings to manage the bot behavior.

How often does AdsBot crawl websites, and can it impact server performance?

Impact is typically low: - Bandwidth usage: minimal - Request rates: limited to specific landing pages - Dynamic load: slight impact if pages are uncached Most websites will not experience noticeable performance issues from AdsBot. Though some administrators choose to rate-limit or restrict it.

What happens if I block AdsBot? SEO, visibility, and feature impact explained.

Blocking AdsBot does not affect organic search rankings, but it can negatively impact advertising performance. Potential effects include: - Landing pages may not be evaluated for quality or policy compliance - Reduced ad quality scores, leading to higher costs or limited delivery - Ads may be disapproved or perform poorly Blocking AdsBot will not have any direct impact on search engine SEO performance.

Does AdsBot collect, scrape, or use my content for training or reuse?

AdsBot analyzes landing page content to evaluate relevance, quality, and compliance with advertising policies. It processes HTML, text, and performance signals but is not designed for general indexing or public data collection. Usage typically includes: - Ad quality and relevance assessment - Policy compliance checks - Landing page performance evaluation It does not publish collected content in open datasets, and there is no documented use of AdsBot for AI training or general content reuse.
