Know which clients need you today

Not every client needs the same attention every week. GapStack gives your team one view across the entire portfolio, so you can quickly see where visibility has improved, where a competitor has moved ahead and which client has the most important opportunities waiting.

For every client, see:

  • Google ranking performance
  • AI mentions and recommendations
  • Citation visibility
  • Competitor movement
  • High-priority Gaps
  • Reporting status and recent changes

Spend less time assembling the picture. Spend more time improving it.

An agency workflow built around the work you already do

GapStack is designed around the daily checks, weekly planning and client conversations that keep an agency moving.

  1. Every morning

    See what changed

    Daily Watch checks your most important AI prompts every day. See when a client loses a recommendation, a competitor appears more often, a new citation is discovered, an important keyword moves, or a monitored answer changes significantly.

  2. Every week

    Review the complete picture

    Weekly Pulse checks every tracked prompt across ChatGPT, Claude, Gemini, Perplexity, Grok and Muse. Follow visibility over time, compare brands vs competitors and identify opportunities from actual answers.

  3. During delivery

    Turn findings into work

    Gaps explain what happened, why it matters and where to start. Assign internally, prepare work from evidence, or connect an AI assistant for a fix plan.

  4. Before the client meeting

    Tell a clearer story

    Branded reports and shareable views show what changed, where they are gaining, where competitors are preferred, what you are doing next and whether prior work had effect. Evidence, priorities and progress.

Gaps

One prioritised action list for every client

Stop building the weekly SEO action list by hand. GapStack finds where each client is missing from Google results and AI-generated answers, then ranks opportunities.

Gaps can identify:

  • Competitors recommended instead of the client
  • Pages missing from AI citations
  • Keywords just outside page one
  • Content competitors cover more completely
  • Weak or missing comparison content
  • Declining rankings
  • Pages that need strengthening
  • Missing evidence for AI inclusion

Every Gap includes evidence.
