It has become increasingly important for brands to compete in AI visibility, which means they need to understand it. There is a range of different AI visibility tools and trackers that can help brands understand where they are ranked and why; we will compare two of them.
There is a new battlefield for brands to fight in within digital marketing: AI visibility. With changes to the way that users are using the internet, brands must increasingly understand how and why their products and services are mentioned in AI search results.
There is an increasingly large range of tools that help brands to better understand, forecast and control how and where they are visible for AI search, and today we will compare two of those tools. SimilarWeb and PromptWatch.
SimilarWeb is Built For Digital Marketing Intelligence
SimilarWeb was originally built as a platform for brands to be able to analyse their own performance and that of competitors, and has broadened to include AI visibility in its features. The AI visibility index that it offers allows brands to see how they are appearing in AI-generated answers, and includes the sorts of topics and prompts that often generate mentions and citations for them, as well as where they lose out to competitors.
SimilarWeb, having been built for broader digital marketing competition analysis, has a range of tools that can analyse website traffic, search performance, audience behavior, competitor performance and other digital marketing trends that could be relevant for any brand competing in such an environment.
Its detailed tool for tracking AI traffic and showing how much traffic AI search platforms route to websites, including which AIs are doing so, can be very valuable for some brands.
PromptWatch Focuses on Understanding How Brands Appear in AI Responses
The objective of PromptWatch is much more confined. It is built for understanding why AI responses choose specific brands, Generative Engine Optimization (GEO) and AI visibility. It can track prompts across multiple AI search tools and measure the rankings, mentions, citations, competitor visibility and sentiment across those AI tools.
It is a specialist tool that is designed to give brands actionable insights from the data that it generates. Some brands might find that visibility data from PromptWatch helps them understand how to optimize content for AI search tools.
How Do They Compare on Price?
While cost isn't everything, the smaller the margin, the more important a consideration it can become. For small to medium enterprises, price can be a real sticking point.
The plans from PromptWatch start at $95 a month and then hit $245 and $579 a month for professional and business, respectively. Focusing on the lowest 'Essential' package, it offers 500 agent credits per month, 1 project, tracking across 4 AI models, 50 prompts, 6,000 responses, agent chat, and MCP and API access.
The services that SimilarWeb provides begin at $99 a month and go up to $333 and $542 a month. The cheapest 'AEO Intelligence' package from SimilarWeb provides 1 user with AI brand visibility, 150 tracked prompts, sentiment analysis, citation analysis and AI traffic.
As you can see, the prices are relatively competitive between the two. It is important to note that while the prices are close, SimilarWeb provides a much broader sort of service, which could be more valuable for many brands. That being said, PromptWatch is $4 cheaper at the basic level, and almost $100 cheaper at the mid-tier.
Which Service Provides More Useful Data?
By far one of the most important considerations, considering that the whole point of AI visibility tools is to get valuable information.
Here, PromptWatch provides a more simplistic set of data. It shows which page attracts AI models, what they cite, and when those citations are clicked on by users.
SimilarWeb, on the other hand, casts a much wider net. It uses an AI traffic tracker to measure traffic referred from AI over time, which includes the models that are generating those visits and which pages or domains are on the receiving end. It is a tool that is designed to be used in concert with other elements of SimilarWeb's suite of digital marketing intelligence tools.
If a brand wants to know specifically the amount of traffic they are getting from AI, PromptWatch does that. If they want to know how their AI traffic compares with the traffic they get elsewhere, or how their competitors' AI traffic is going, SimilarWeb is better.
Does One Track Citations and Prompts Better?
PromptWatch has functionality in its platform that allows brands to monitor the sorts of prompts that users ask, identify the sources that AI will cite, and compare how brands are mentioned and determine when a competitor is out in front on any of these metrics.
SimilarWeb might not have the specific tools that PromptWatch does for these functions, but it has its own tools. SimilarWeb can check which prompts lead to which AI answers, find the sources that are most valuable for mentions and create visibility benchmarks against competitors' mentions.
Despite PromptWatch being focused on doing this exact thing, SimilarWeb can do it as well and brings a broader layer of digital intelligence along for the ride.
Which Tool Is Best For Your Brand?
While PromptWatch might be the right tool for a specialist team aiming to conquer GEO or a marketer who needs to monitor AI visibility and nothing else, that is probably not a realistic representation of what a brand wants to do.
If AI visibility is something that matters as part of a broader digital strategy, SimilarWeb wins out by a mile. It lets brands track mentions and citations from AI search, while also being aware of how much traffic these generate and where competitors sit.
To cut a long story short, SimilarWeb can do pretty much everything that PromptWatch can, but it can do a lot more as well.
