Why it matters
Buyers Ask AI Before They Visit Your Site
People now ask ChatGPT and Google's AI which product to buy. The answer names a few brands and cites a few pages. If yours is missing, you lose the buyer before they reach a search result.
58%
Ahrefs found AI Overviews cut clicks on top Google results by 58%.
How it works
See It, Understand It, Fix It
Tracking alone tells you that you lost. TDC Signal runs one weekly loop that also tells you why, and what to change.
Step 1: See
Know Where You Stand
Track the questions buyers ask on six AI engines, daily or weekly, in the countries and US states you sell to.
- Visibility, position and share of voice per question
- Sentiment with the exact sentence as evidence
- Every source and page AI cites
- The full answer with your brand highlighted
Step 2: Understand
Learn Why You Lost
For each question you miss, see what the AI searched for and which pages won instead of yours.
- The background searches the AI ran
- The winning pages and what they cover
- Questions with no matching page on your site
Step 3: Fix
Change the Answer
Score each page for AI readiness and get drafts for the content that is missing. You approve every draft.
- Page audits with a fix list per page
- Drafts for pages, FAQs, comparisons and structured data
- An impact timeline that marks each fix
Then measure. The next checks show whether each fix moved the answer.

FAQ
Questions About TDC Signal
What is AI visibility?
AI visibility measures how often AI answers mention and cite your brand for the questions your buyers ask. TDC Signal also tracks your position in each answer, the sentiment, and your share of voice against competitors.
Are AEO and GEO the same thing?
Nearly. Answer engine optimization (AEO) aims to get your page quoted as the direct answer. Generative engine optimization (GEO) aims to get your brand named and cited in answers AI writes from several sources. TDC Signal covers both.
Which AI engines does TDC Signal track?
ChatGPT, Perplexity, Microsoft Copilot, Gemini, Google AI Mode and Google AI Overviews. The Free plan tracks ChatGPT. Starter tracks any 3 you pick, and Growth and Agency track all six.
How is this different from an SEO tool?
SEO tools rank links on a results page. TDC Signal reads the answers AI writes, shows which sources it trusts, explains why a competitor won, and drafts the change that closes the gap.
Does TDC Signal change my website?
No. TDC Signal drafts pages, FAQ sections, comparisons, structured data and llms.txt files. You approve each draft and publish it yourself, then mark the date so TDC Signal can measure the impact.
Does it work for online stores?
Yes. Upload a CSV of your top products or paste their product page links. TDC Signal shows which products AI recommends and flags shopping cards that show a different price or an out-of-stock product.
