Row checks
Checked by script on the 25 rows you pasted (A1 to A25). Match fields counted: company name, website, email domain, LinkedIn page URL. Your file has no stock symbol column. These checks cover these 25 rows only; I do not project them to the other 387 rows.

| Rows with any flag | 8 |
| Rows checked | 25 |
- A8 has no match field at all, so LinkedIn has nothing to match it on.
- A2, A7 and A17 use a page URL that ends in a number ID. For best matching the URL should end in the company name.
- A1 and A11 share brightlinelogistics.example, and A9 and A24 share tamarack3pl.example. They may be the same company twice; A11 and A24 also have fewer fields filled.
Headers: build the upload on LinkedIn's template and keep its headers exactly as they are. Changing or removing template headers causes an upload error. I cannot confirm from the saved sources that your column names match the template.
List size check
Rule from Platform facts: under 300 rows cannot be uploaded; LinkedIn recommends 1,000 or more companies.
| List | Rows | Status |
|---|---|---|
| Tier 1 | 118 | cannot upload (under 300) |
| Tier 2 | 294 | cannot upload (under 300) |
| Tier 1 + Tier 2 combined (one list) | 412 | can upload, under the 1,000 advice, if 300 or more rows remain after cleanup |
| Rows the combined list can lose in cleanup and still reach 300 | 112 | 412 minus 300 |
Neither tier can be uploaded on its own. Each company list audience comes from one single list, so to target both tiers in one audience they would need to be one file. Options, all your call and HELD: 1. Upload one combined list as one audience. Every ad that uses it reaches both tiers alike, so the message cannot differ by tier. Cleanup (dropping rows like A8, merging duplicates like A11 and A24) lowers the 412; the list stays uploadable only while 300 or more rows remain. I cannot count the full file's cleanup from 25 rows. 2. Add more accounts you supply until each tier reaches 300 rows.
Refinements
- Job function: Operations. Seniority: Director and above. Both are refinements LinkedIn allows on a company list.
- Location is a required targeting facet, and your input does not name one (question 1).
- The final audience must match at least 300 member accounts to run. A 412 company list narrowed to Operations Directors and above may fall short; LinkedIn will show the count after upload, so I do not estimate it.
Timing
| Item | Value |
|---|---|
| Audience build time | up to 48 hours |
| List expires if no active or draft ad set uses it | 90 days |
Upload plan (held)
- HELD: fix A2, A7 and A17 page URLs to the name form, if you have them.
- HELD: fill or drop A8; merge or drop the A11 and A24 duplicates.
- HELD: pick option 1 or 2 above.
- HELD: upload the list in Campaign Manager, Audiences, using LinkedIn's template.
- HELD: attach it to a draft ad set within 90 days, with location, Operations and Director and above.
| Lists by status | Count |
|---|---|
| Cannot upload | 2 |
| Can upload, under advice | 1 |
| Meets advice | 0 |
Questions for you
- Which locations should the campaign target?
- Do you want one combined list with one message for both tiers (option 1), or to grow each tier to 300 so each tier gets its own audience and message (option 2)?
- Are A1 and A11, and A9 and A24, the same companies?
- Can you run the same checks on the full 412 row file, or send it so I can?
Needs your decision
- Upload any list or change any campaign: HELD.
