A resume you send is read by somebody who already has a role in mind. A resume you post has to be found first, and then has to answer a question the reader has not asked yet.
Lead with the role, not the history
The first line should say what you do and what you are looking for: "Electrician, eight years, looking for full-time work". An employer scanning a list is matching that line against a vacancy. A chronological history starting in 2014 makes them do the work, and they will not.
Leave out what you would not hand to a stranger
A posted resume is public. Your full home address, your date of birth, your identity-document numbers and your photograph are not needed to get an interview, and they are exactly what identity fraud is assembled from. Your area, your field and your experience are enough to be contacted.
Your phone number is not needed either — on this site it stays private and is exchanged only when both sides confirm.
Use the words an employer would search
Job titles as they are actually advertised, tools and certifications by name, and the area you can work in. Not "dynamic professional". Somebody is typing a trade and a place into a search box; be the thing they typed.
Give evidence in numbers where you can
"Managed a team" is a claim; "managed a team of six across two shifts" is a fact somebody can picture. Years, volumes, sizes, tools by name. This matters more in a posted resume than a sent one, because there is no covering letter doing the work and no interview scheduled to fill gaps.
Write for someone skimming twenty of these
Short paragraphs, no dense block of prose, and the most relevant experience first even if it is not the most recent. An employer reading a list of candidates gives each one a few seconds; structure is what survives that.
Keep it current or take it down
A resume from eleven months ago is read as somebody who stopped looking. Refresh it or remove it — an expired listing is worse than none, because it is the one an employer wasted a message on.
Post once and point everything at it
A single current listing you can send anybody is worth more than a resume attached to forty applications, because it is a link that keeps working after the conversation. Put it wherever you already are — a message to a former employer, a note in a trade group — and let it be the thing that answers "what are you looking for?" while you are asleep.
Post it in Resumes, or start a new listing.
