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.

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.

  1. 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

  2. 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

  3. 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. Paid plans 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. Import your catalog from Shopify, WooCommerce or a Google Merchant feed. TDC Signal shows which products AI recommends and flags wrong prices or out-of-stock products that AI still suggests.
