The emergence of AI and generative search is transforming how users seek and find information on the web. As these models continue to evolve, their presence is increasingly felt within our familiar search environment. The truth is, the web is being reshaped, not just for human visitors, but for automated readers.
AI crawlers such as Perplexity, ChatGPTBot, and ClaudeBot visit sites now more than ever before, and oftentimes without us even knowing.
What Are AI Crawlers and Why They’re Increasing
Some big questions facing marketers today are: how do I respond to this shift? Should I allow AI crawlers to crawl my website? If I do block them, will there be any impact on my site’s visibility? Are there negative implications for allowing them to crawl my site? This article will help answer these questions by explaining what AI crawlers do, how they can impact your site, what will happen when you block them, and, most importantly, help you make the most informed decisions.
What Do AI Crawlers Do?
AI crawlers, also known as AI bots or data scrapers, are automated programs that browse, index, and collect content from websites, often with the purpose of training or feeding large language models (LLMs). AI crawlers crawl sites automatically, and the collected data can be used to train or fine-tune models that power AI-driven search engines.
The most common bots found are GPTBot from OpenAI, ClaudeBot from Anthropic, CCBot from Common Crawl, and PerplexityBot.
How Do AI Crawlers Differ from Google Bots?
While it might sound like these are the same thing, AI bots do not index content for search results like Google or Bing Bots. AI crawlers are used to feed models responsible for generating summaries and answers.
Why is Their Activity Increasing?
When you use an AI search engine, much of the summarized or answer-ready information generated is drawn from content that AI crawlers have collected from across the web. The growing demand for AI tools and search experiences has led to an increase in web crawling activity to supply these systems with data.
Why Managing AI Crawlers Matters for Organizations
As AI crawlers become more active, their presence creates new operational and strategic challenges that organizations can’t ignore.
- Control over Data: Once your content is collected by AI crawlers, you lose visibility into where it goes and how it’s represented in large language models. For mission-driven or research-focused organizations, this can raise concerns about accuracy and attribution.
- Performance Impact: Unpredictable spikes in automated visits can disrupt sites, slowing them down or crashing them altogether. Even brief interruptions can erode user trust and affect key conversion or engagement metrics.
- Bloated Analytics: Heavy bot activity can distort your website’s traffic data, inflating visitor counts and engagement numbers. That makes it harder to distinguish real user behavior from automated activity, making it harder to measure marketing ROI accurately. Most analytics platforms now allow filtering known bot or crawler traffic. Reviewing these settings helps ensure that your engagement metrics reflect genuine user behavior.
- Legal Questions: Beyond operational and technical challenges, there are questions being asked about content ownership and data ethics. Organizations should consider whether the use or reuse of their web content by AI models aligns with their policies, licensing agreements, or privacy standards. While regulations are still catching up, acknowledging this dimension ensures your decision is forward-looking.
These combined pressures are prompting leadership teams to pause and ask a critical question: Should we continue allowing this activity, or start managing it more deliberately?
The Question: Should You Block AI Crawlers from Scraping Your Site?
Given this, the key question in many marketers’ minds is whether or not to block AI crawlers from scraping their site. Unfortunately, there is no one-size-fits-all answer or solution, as the decision is comprised of several factors that require careful consideration. Your choice will be rooted in your organization’s goals, internal infrastructure, and comfort level in how your content might be displayed and used.
Your Options: Allow, Block, or Control Access
There are three approaches you can consider when making this decision: Allow, Block, or Control Access. Many organizations are still evaluating their stance, with some choosing to block AI crawlers entirely, while others take a wait-and-see approach and monitor activity and revisit policies as AI search tools mature.
Option 1: Allow AI Crawlers
Allowing AI crawlers increases your content’s visibility and potential reach. When your site is scraped, your material may appear in AI-generated search results or summaries. However, you’ll have less control over how it’s represented, and automated traffic may rise. If your organization values openness and visibility, this may align with your goals.
Option 2: Block AI Crawlers
If you elect to block AI crawlers, you’ll be preventing them from scraping your site and collecting data from it. This will prevent your content from being displayed and reused without permission in AI search results. This approach will not hurt your SEO efforts, since Google Bots and other traditional search tools index content separately; however, it might limit your organization and organization’s content from appearing in AI-powered search experiences.
Additionally, blocking AI crawlers can help you protect your organization from unexpected downtime, as it reduces server load and helps protect bandwidth.
If your organization’s web presence has proprietary, sensitive information or high-value content, you may want stronger control over how your data is collected. If this is the case, you may want to consider implementing changes to your robots.txt file to prevent AI crawlers from scraping it.
How to Block AI Crawlers Using Code:
User-agent: GPTBot
Disallow: /
User-agent: *
Allow: /
The snippet above will block GPTBots while allowing other search crawlers, like GoogleBot are allowed to crawl.
Option 3: Elect for A Hybrid Approach
Taking a hybrid approach provides flexibility. This approach can allow you to grant access to verified crawlers while blocking those that cause performance issues or unclear intent. To ensure you’re only allowing verified crawlers, we recommend you monitor your server logs to get a sense of what bots are active and adjust your rules as needed.
If you’re concerned with limiting your site’s visibility but cognizant of performance issues, this approach might make the most sense for you. This approach allows your organization to participate in the AI search ecosystems while also maintaining control and oversight.
How to Decide What’s Right for Your Organization’s Website
If you’re feeling unsure which direction to take, follow the 5 steps below to help clarify your decision:
- Review Current Crawler Activity: To set yourself up for making the best decision, get grounded by understanding your site’s current crawler activity. Doing so will help you know what types of AI bots are visiting your site and how frequently they are visiting.
- Gauge Your Content Sensitivity: Review the content on your site and evaluate what is public, proprietary, or restricted.
- Evaluate Your Site’s Infrastructure: Reach out to your hosting provider to evaluate if your environment can handle increased crawler traffic. You may want to consider allocating more resources if you’re not satisfied.
- Decide Your Openness to Scraping: You will ultimately need to decide if you want to open, control, or monitor the data scraping on your site. Meet with leadership to ensure you’re aligned and that your decision reflects your organization’s goals and overall mission.
- Document & Revisit: As AI continues to evolve and shape the search landscape, your policy must evolve too. This policy should be owned jointly by marketing and IT, and revisited at least twice a year as AI tools, crawlers, and standards evolve.
In Summary: Take a Measured, Informed Approach
The rise of AI brings an inevitable increase in AI-powered crawlers that now search alongside us. As search continues to evolve, organizations must decide how they’ll engage with this new digital reality. The goal isn’t to resist AI but to manage how it interacts with your content, intentionally, transparently, and in alignment with your mission. By leading with awareness instead of alarm, you can stay in control of how your digital presence is used in the AI era.
