Your pitch ends with a link, and the link does most of the closing. If a brand taps through to an empty page, the conversation dies there. So the page goes up before the pitching starts.
What has to be on it
Three things, and none of them are hard.
One sample, pinned at the top. The video you just filmed. One is enough to start. A brand watching ten seconds of you on camera learns more than a paragraph about you could tell it.
A niche, in plain words. "Skincare for sensitive skin" is bookable. "Lifestyle" is not. Name the thing you would be the obvious choice for, even if it feels narrow. Narrow is the point.
Two lines about you and a starting rate. Who you are, what you make, who you make it for. A number, or a range, so you read as someone who does this rather than someone thinking about it. A rate on the page also means you are not negotiating from scratch in a DM later.
Why one link beats a DM full of files
A brand contact almost never says yes alone. They forward you. A link survives being forwarded, opens on a phone, and looks the same to everyone who sees it. Four video attachments and a wall of text do not.
It also means every brand you pitch sees the same credible page, so you stop rewriting who you are in every message.
Do not wait until it feels finished. Nothing is finished. One sample, a niche and a rate is a portfolio you can pitch behind today, and the second and third samples slot in later without touching the link.
