The document summarizes a VC's views on marketing tech businesses. Some key points include: focus on retention and contribution over acquisition costs; rely on white hat SEO practices; use blended customer acquisition costs that consider both paid and unpaid channels; track the most important metrics rather than too many numbers; address major drop off points in the sales funnel; and have personality, be creative, and be bold in marketing approaches. Testing is important but shouldn't be the only approach used.
