LinkedIn campaign (ad set) performance

Reports spend, impressions, clicks, CTR, CPC, CPM, leads, cost per lead and website conversions for a window, per campaign (an ad set in Campaign Manager) and in total, next to the equally long window before it so every number has a baseline. Use when: the user asks how LinkedIn is doing, before recommending any budget or bid change, and to decide which campaign is worth more money. Start here, not with a list tool. Do not use it for a brief or a report to keep or forward: that is generate_report_now (monitoring router), which covers every connected account and saves a page. Do not judge a LinkedIn campaign on a day or two: at typical B2B volumes a single day is noise, and LinkedIn's cost per lead is an order of magnitude above other channels by design. Use last_7_days at minimum, last_30_days for a decision about money. Do not read a rise in CPC as failure on its own — on LinkedIn it usually means the auction got busier, and the number that matters is cost per lead. Returns account totals with period-over-period change, plus a per-campaign table sorted by spend. LinkedIn ad accounts carry no reporting timezone, so every window here is UTC days. If the user has not said which window, use last_30_days and say so. If a campaign shows spend but zero leads, check linkedin_list_conversions before concluding the ads are bad — an unattached conversion rule reports nothing.
