A ready string for Sales Navigator, no signup.** Use it at https://tools.joinvalley.co/linkedin-boolean-search-sdrs Part of the [LinkedIn Boolean search builder](https://tools.joinvalley.co/linkedin-boolean-search). ## What's the Boolean string for SDRs and BDRs on LinkedIn? Every title it covers, and what it leaves out. In Sales Navigator, paste this into the title filter: (SDR OR BDR OR "Sales Development Representative" OR "Business Development Representative" OR "Sales Development Rep" OR "Business Development Rep") NOT (manager OR director OR head OR VP OR intern). It covers 6 ways people write the title and leaves out manager, director, head, VP, intern. | Title | In or out | Why | | --- | --- | --- | | SDR | In | The short form. | | BDR | In | The short form of the business development title. | | Sales Development Representative | In | The spelled-out form. | | Business Development Representative | In | The spelled-out form. | | Sales Development Rep | In | LinkedIn matches a quoted phrase exactly, so each wording needs its own entry. | | Business Development Rep | In | LinkedIn matches a quoted phrase exactly, so each wording needs its own entry. | | manager | Out | Leaves out the people who run SDR teams. Remove it, and the next three, to find them instead. | | director | Out | Same: team leads, not reps. | | head | Out | Same: Head of Sales Development. | | VP | Out | Same: VPs of Sales Development. | | intern | Out | Keeps out interns. | Our picks, not LinkedIn's. Add or remove titles in the builder above and the string updates.

Edit any of them, switch product, or add keywords, and the string updates. Everything runs in your browser, and nothing you type is sent to us. Quotes, parentheses and capital operators go in for you, following LinkedIn's Boolean rules, and the checker below the builder flags anything LinkedIn won't read the way you meant. ## Reps, not the people who run them. And how to flip it. The same words appear in the rep's title and the manager's. ### Why the string leaves out managers "Sales Development" is in an SDR's title and in their manager's. Leaving out manager, director, head and VP keeps the list to reps. ### To find SDR managers instead Swap the lists: put SDR Manager, Head of Sales Development and Director of Sales Development in the titles, and leave the leave-out list empty. ### It fits Sales Navigator's cap Sales Navigator takes at most 15 Boolean operators in one search. This title string uses 10, so there's room for a few more variants.
