Which one is for you
Pick Serpfox if
- Fits if you only track Google and want daily numbers for $10 a month on yearly billing
- Works for checking whether AI assistants name your business or a rival
Look elsewhere if
- Skip it if you need Bing, Yahoo or any engine other than Google
- Tight if you want AI prompts checked daily, which starts at Pro 1000 for $50 a month
- Not for you if you want client logins or white label on a small plan, as Starter has neither
- Watch out: desktop and mobile each count as a keyword, so tracking both halves your allowance
- Tight if you stay free, at 10 keywords and 3 AI prompts checked weekly
Pick SERPtag if
- Fits if you run a small site and a weekly ranking check is enough
- Works for freelancers who want to see whether ChatGPT or Perplexity mention them in the same tool
Look elsewhere if
- Pricey if you need daily checks, since Growth goes from $39 to $189 a month paid monthly
- Tight if you want the API, MCP server, custom-branded reports or 10 users, which only come with Agency
- Not for you if you want a free plan to keep, as there's only the 7-day trial and a few single-use tools
- Tight if you're on Starter, which stops at 5 projects and 20 AI analysis credits
- Watch out: the pricing page shows pounds by default, and you have to switch it to see dollars
How we grade them

|---|---|---|
| Value for money | BStarter 100 is $10 a month on yearly billing ($12 monthly) for 100 keywords checked daily plus 10 AI prompts. That's right on the line of the cheapest quarter of rank trackers. Client logins and white label wait for Pro 1000 at $50. | BStarter is $5.83 a month on yearly billing ($7 monthly) for 50 keywords checked weekly, at the very bottom of what rank trackers charge. Daily checks on the same 50 keywords are $20.83, about the category's middle, so the low price only holds if weekly is enough. |

Ten keywords is a cap most sites will hit fast, though. | CNo free plan, but a 7-day trial that asks for no payment up front. Past that there are just a few free single-use tools. |
| Features | CDaily Google rankings by city or country on desktop and mobile, AI answer tracking with share of voice against up to 10 rivals, scheduled reports, alerts and a JSON API. The gap the listing names: it's Google only, and Starter checks AI prompts only weekly. | BGoogle, Bing and Yahoo rankings on desktop and mobile in 190+ countries down to city level, AI visibility on every plan, a separate Baidu tracker, keyword research and white-label reports. It covers the whole job, though the API, MCP server and custom branding wait for Agency. |

It's a web app where you set up projects, keywords and places, and choose weekly or daily checks when you buy, before it tells you much. |

What it does have is a JSON API covering everything in the dashboard, so rankings can go into your own tools. | BWeb only, with no desktop or phone app. Agency adds an API and an MCP server that works with Claude and Cursor; below that plan the listing shows nothing to connect it to. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
