Written answers to the questions buyers actually type. Each one opens with a summary that stands on its own, and is dated so you know how current it is.
Some of the gap is by design. The rest is a defect, and the two need separating before anyone makes a budget decision.
Google Ads and GA4 report different conversion counts because they use different attribution models, different attribution dates, and different session definitions. A stable gap of roughly five to fifteen percent is normal. A large, unstable, or directionally odd gap usually indicates duplicate event firing, broken cross-domain measurement, or an unverified conversion action.
The margin on a fixed-fee project is decided before anyone writes code.
A fixed-fee statement of work protects margin through four mechanisms: an estimate built from decomposed work rather than a buffered guess, a written assumptions list, an explicit exclusions list, and acceptance criteria that make "done" testable. Projects that lose money almost always failed at one of those four in the document, not during delivery.
The role is widely advertised and inconsistently defined. Here is the version that describes a job rather than a title.
A fractional technical project manager owns delivery for an organization part-time, typically two to four days a week, covering estimation, sequencing, scope and change control, QA, and client-facing communication for technical work. The role differs from a full-time PM in availability and cost structure, and from a consultant in that a fractional PM has operational responsibility for shipping, not just recommendations.
