Thank you for contributing to SellerCrowd! Our community relies on accurate, timely information to support their sales.


Please review these guidelines to understand the types of contributions that add value—and what to avoid.



How to contribute valuable data?

Contributions from our community of experienced advertising professionals help each other stay informed on key advertisers and agencies.

Here’s what to look for when sharing:


Client-side contacts

  1. Current Role: What is their current role at the company?

  2. Media Types Managed: What types of media do they handle?

  3. Decision-Making Power: Are they a decision maker?

  4. LinkedIn Profile: Do they use LinkedIn? If so, add a link to their profile.

  5. Contact Info: Include a working email address if possible.

  6. Relevance: Why is this contact useful for SellerCrowd?

  7. In-House Duties: Are there media or marketing tasks handled in-house? If so, who is responsible?

Example: "Sarah Lee, Media Manager at XYZ Corp, manages digital media spending. [LinkedIn link]"

Agency-side contacts

  1. Location: Where is their office located?

  2. Current Role: What is their role at the agency?

  3. Client Work: Which clients do they support?

  4. Media Types Managed: What media types do they handle for each client?

  5. Team Members: Who else is on their client teams?

  6. Decision-Making Power: Are they a decision maker?

  7. LinkedIn Profile: Do they use LinkedIn? Add a profile link if available.

  8. Contact Info: Include an email address if possible.

  9. Relevance: Why is this contact relevant for SellerCrowd?

  10. Client Departures: Do you have confirmed information on clients leaving the agency soon or who have recently left?

Example: "John Doe, Media Buyer at XYZ Agency, handles Programmaatic for Client ABC. [LinkedIn link]"

Agency teams

  1. Team Members: Who is on the team supporting each client?

  2. Roles and Responsibilities: What does the team do for the client?

  3. Changes in Personnel: Are the contacts still there? Has anyone joined or left recently?

Spending tips (Upcoming Spend)

  1. Only Share Active Spend: Only include confirmed, upcoming budgets.

  2. Advertiser Name: What is the name of the advertiser?

  3. Media Type: What types of media are planned?

  4. Direct or Agency: Is the spend direct from the client or managed by an agency?

  5. Agency Location: If managed by an agency, where is it located?

  6. Target Audience: Which audience is this spend targeting?

  7. Budget: What is the estimated budget?

Out of office messages (OOO)

Out of office messages are great for sharing (and confirming) contacts and their teams. Share OOO information only if it includes a relevant backup contact or insights about the team structure.


How NOT to contribute

Avoid submitting the following types of information, as they don’t align with SellerCrowd's focus:

Outdated Information

  1. Ensure that contacts are still active in their roles.

  2. Only share contacts you’ve communicated with recently.

  3. Avoid copying data from other sources like MediaRadar or Winmo without verifying its relevance.

Non-Buying Contacts

SellerCrowd focuses on contacts involved in media buying decisions. Avoid adding people in roles like:

  1. CEOs

  2. Finance

  3. Sales

  4. Design

  5. Technology

End-of-month backlog

Avoid submitting a large volume of information right at the end of the month, as this can slow down our review process.


Thank you for helping keep SellerCrowd a valuable and relevant resource for everyone in the community!
