A hiring manager or a prospective client spends under a minute on a marketing portfolio before deciding whether to keep reading. In that minute they are not checking whether you know what SEO or PPC is. They are checking whether you can prove you moved a number that mattered. Most portfolios fail this test not because the work behind them was weak, but because the page lists skills instead of proving them. This guide covers what a strong digital marketing portfolio actually contains, with separate detail for an SEO specialist, a PPC specialist and a marketer running several channels at once, plus how to handle numbers you are not allowed to share in full.
