How we grade them
| 1.4GPABidXWeak | 2.2GPASellerAppFair | |
|---|---|---|
| Value for money | DBidX Essential is $195 a month for up to $10K of ad spend, a pared-down version without individual rules. Graded against the ad tools it's listed beside, that's more than Teikametrics' $149, which does more. The full platform is $495 plus an unpublished share of spend, on an annual commitment. | CPro is $99 a month and up, rising with your ASINs, ad spend and revenue. The FAQ says yearly billing saves 50%, but no yearly price is shown. That's inside the normal range here. The Smart Plan, with an account manager, is $250 after $149 for the first 3 months. |
| Free plan and trial | FNothing free: no free plan and no trial. New customers can take a paid three-month proof of concept instead. Only the Share of Voice add-on has a free part, the first 100 keywords. | CFreemium is free for as long as you like, with no card: basic product research, an advertising overview, campaign manager and listing quality checks. Access is limited, so it's a taster rather than a plan you'd run a store on. |
| Features | CBulk campaign creation, nightly keyword, bid and budget automation, Amazon DSP, Marketing Cloud reports and a Share of Voice add-on. It covers ads well, but Essential is pared down, bids change nightly rather than hourly, and it's ads only. | CRule-based PPC automation with hourly bids and dayparting, a profit dashboard per ASIN, listing scores and an extension. Product research is the basic part, and there's nothing on record for inventory, review requests or reimbursements. |
| Ease of use | CNo rating on record. It pulls 90 days of ad data when you connect and builds campaigns in bulk, but there are ad accounts to link and automations to set up. | CNo rating on record. Bid rules, dayparting and profit tracking all need your seller and ad accounts connected and your costs filled in, and there's a fair bit to learn. |
| Platforms and integrations | CWeb only, with no phone or desktop app. It connects to Amazon Ads, Amazon DSP, Marketing Cloud and Walmart, with ChatGPT for keyword ideas. One account handles one Amazon account per region by default. | BWeb and a Chrome extension, with no phone or desktop app. It connects to Seller Central, Amazon Ads, Amazon DSP and Amazon Marketing Cloud, and there's a data API billed by usage. |
| Best for | automating Amazon ads and DSP | automating Amazon PPC with profit in view |
