Birch (formerly Revealbot) vs Free Google Ads Negative Keywords Generator in 2026: Paid-media operations vs a manual search-query aid
Birch is a spend-based platform for automating and analysing active ad accounts. Free Google Ads Negative Keywords Generator is a no-account browser tool that creates a reviewable starting list for Google Search exclusions.
Birch (formerly Revealbot)
Free Google Ads Negative Keywords Generator- The free generator creates Google Ads negative-keyword ideas from a main keyword, product, or service plus an industry and Global or India setting.
- It separates Recommended Negative Keywords from Review Before Adding, acknowledging that terms such as free, course, guide, or download can be commercially valuable in some accounts.
- Birch automates connected Meta, Google, TikTok, and Snapchat accounts with nested rule conditions, custom metrics, external data, logs, and more than 20 actions.
- Birch Rules can check every 15 minutes or run on a custom schedule, while Birch AI drafts rules for user approval rather than activating them automatically.
- No account login, Google Ads connection, Search Terms Report import, automatic sync, API, or published usage limit was found for the free generator.
- Birch Stage can build Meta, TikTok, and Snapchat ads from Google Drive and Sheets after a preview, which is unrelated to generating a negative keyword list.
- The generator’s page tells users to check suggestions against their Google Ads Search Terms Report before adding exclusions.
The Free Google Ads Negative Keywords Generator should not be evaluated as a smaller Birch. It performs one narrow task: a marketer enters a keyword, product, or service, selects an industry and either Global or India, then reviews negative-keyword suggestions in broad, phrase, or exact match formats. Birch, formerly Revealbot, is an account-operations product for teams already managing Meta, Google, TikTok, and Snapchat campaigns. It brings rules, custom metrics, analysis, reporting, creative launch, integrations, and reviewable AI assistance into that workflow. The free generator can help an advertiser make a safer first pass through obvious irrelevant intent, but it has no documented Google Ads connection, Search Terms Report import, account sync, automation, or support commitment. Birch costs according to connected monthly ad spend, with Essential shown at $49 per month billed annually and Pro at $99 per month billed monthly at the displayed up-to-$10,000 setting. The generator is free, which reflects its manual, single-purpose role.
The tools at a glance
Birch (formerly Revealbot)
Paid-media automation, creative launch, performance analysis, and server-side Meta tracking for active ad accounts
Birch is a paid-media operating layer for teams that already have active accounts and recurring maintenance work. Its Rules product spans Meta, Google, TikTok, and Snapchat, allowing nested AND and OR conditions, custom metrics, relative ranking, timeframe comparisons, and more than 20 actions. A team can use platform data alongside Google Sheets, Google Analytics, AppsFlyer, Adjust, Hyros, or Wicked Reports data, then receive email or Slack notifications and inspect activity logs. This is designed to make account operations repeatable, not to create an isolated list of search exclusions.
Birch’s workflow is broader than a rule builder. Explorer supports comparisons, trend charts, creative or post-ID grouping, custom timeframes, fatigued-ad views, and best-performer views. Stage combines Google Drive media and Google Sheets plans to make Meta, TikTok, or Snapchat ads, with previews and up to 1,000 Sheet rows per run. Reports can be scheduled across platforms and Birch publishes white-label-report, alert, and audience-analysis capabilities. Birch AI can convert a written goal into a draft rule, assess performance questions, or audit a rule setup, but the profile says users approve suggestions before a rule goes live.
Essential has reporting and basic workspace functions, while automated Rules, Explorer, Launcher, custom metrics, and Top Audiences sit on Pro and Enterprise. Prices are spend-based: at the public page’s displayed up-to-$10,000 monthly connected-ad-spend setting, Essential is $99 monthly or $49 monthly billed annually, and Pro is $99 monthly. That makes Birch worth considering only where ongoing multi-account or multi-channel management will use the operational layer. It can support rules involving Google account data, but the reviewed profile does not establish it as a dedicated negative-keyword generator or a replacement for reviewing search queries in Google Ads.

Free Google Ads Negative Keywords Generator
Free browser-based starting list for Google Ads negative-keyword ideas and match-type formatting
Free Google Ads Negative Keywords Generator is a simple browser utility from OnlineMarketingBull. A user enters a main keyword, product, or service, chooses the closest industry, selects Global or India, and generates suggested exclusions. It then offers broad, phrase, and exact negative-keyword formats and lets the user copy or download the output. This can save a new search campaign from beginning with a wholly generic jobs-and-free list, because the result is framed around the entered offer and industry rather than a fixed universal checklist.
Its best design decision is showing two groups. Recommended Negative Keywords covers intent that is commonly unsuitable for a commercial search campaign, while Review Before Adding separates terms that may be wrong for one advertiser and valuable for another. Free, cheap, course, training, guide, PDF, and download are not inherently bad terms. A local service business may exclude them, while an education company could remove its own demand by treating them as automatic negatives. The tool’s page explicitly says to review suggestions against the account’s Google Ads Search Terms Report before adding exclusions.
There is no documented login, paid tier, account connection, search-term import, automated sync, API, integration, scheduled update, usage limit, or support commitment. That is not a defect in a free utility, but it sharply defines the product’s role. It produces a manual starting point, then the advertiser must validate and upload the final list in its campaign workflow. Choose it for a fast first-pass list on Google Search; choose an account-management product such as Birch only if broader active-account operations are already the buying need.

Which should you choose?
Free Google Ads Negative Keywords GeneratorBirch (formerly Revealbot)Birch (formerly Revealbot)Birch (formerly Revealbot)The utility and Birch sit at opposite ends of the workflow. The generator is useful before or during a manual cleanup task, when a marketer needs prompts for exclusions and a reminder to distinguish obviously irrelevant intent from terms that need business judgment. Birch is useful after a team has enough account activity that rules, reporting, external data, and reviewed changes need to become repeatable. Price is not a quality signal here: one product is free because it has no documented account connection or automation; the other charges around active connected-ad-spend operations.
Bottom line
Use Free Google Ads Negative Keywords Generator when starting a Google Search campaign or cleaning a small account and you want a no-cost, industry-aware list to review. Keep its Review Before Adding terms out of bulk upload until they have been checked against the offer and Search Terms Report. Use Birch Pro when repeated monitoring, custom thresholds, alerts, analysis, and account actions across Meta, Google, TikTok, or Snapchat justify a spend-based operating tool. Birch is more capable, but it is not a justified purchase merely to create negative-keyword ideas.
Frequently asked questions
Is Birch worth paying for instead of using a free negative keyword generator for a small Google Ads account?
Birch is not worth paying for solely to create negative-keyword ideas for a small Google Ads account, because the free generator already creates a reviewable starting list and Birch is built for wider account operations. Birch becomes relevant when recurring rules, reporting, external data, alerts, analysis, or multi-platform campaign work would replace meaningful manual maintenance.
Can the Free Google Ads Negative Keywords Generator automatically add exclusions to my Google Ads campaigns?
The Free Google Ads Negative Keywords Generator does not document automatic Google Ads campaign changes, account login, search-term import, or sync. It produces broad, phrase, or exact-match suggestions that can be copied or downloaded, after which the advertiser must review them and apply any chosen exclusions through its own Google Ads workflow.
Why does the negative keyword tool put free, course, and guide into Review Before Adding?
The tool puts terms such as free, course, and guide into Review Before Adding because their value depends on the advertiser’s business model and campaign intent. A local service provider may want to exclude tutorial demand, while a training business may want it, so treating the terms as automatic negatives could remove worthwhile searches.
Can Birch use Google Sheets data to automate paid-media decisions after I review search terms?
Birch can use Google Sheets data inside its paid-media workflow after a team has defined and reviewed the rule logic, because the reviewed profile lists Sheets among external data sources for rules, reports, and Explorer. The profile does not document a dedicated Search Terms Report import or automatic negative-keyword recommendation feature, so confirm that specific workflow before relying on it.
Which option is safer for building a first negative keyword list for a local service campaign?
The Free Google Ads Negative Keywords Generator is the safer first step for building a local-service negative list because it explicitly separates recommended exclusions from terms that need review and directs users to compare output with the Search Terms Report. Birch can enforce broader account operations, but the reviewed product profile does not position it as a specialised negative-keyword ideation tool.
