No. Yola is a no-code builder made for people who are not developers, so the real work is choosing which projects go up and writing the credit line under each one. You pick a template, upload your images, type the captions and publish. Nothing in it asks you for a line of code.
You can build and publish on the free plan without paying anything. A paid plan is $9.95/mo and brings a custom domain, more pages and the full AI tools, with a free domain for the first year on annual billing. Current plans are listed on the pricing page.
They do different jobs. Upwork and Fiverr put you in front of buyers who are already looking and take a cut for doing it, and your profile sits inside somebody else's search results alongside thousands of others. Your own site is the link that goes on a resume, in a LinkedIn profile and at the bottom of an application, where a marketplace profile reads as the wrong sort of answer. Plenty of people run both, showing the work properly on the site and finding the buyer on the marketplace.
Six to ten, and fewer if the tenth is weak. You are read in about a minute, so every extra project takes attention from your strongest three. Choose the ones closest to the work you want next, even when they are not the ones you are proudest of. Anything else can live in a PDF you send when somebody asks.
Say what you did, then what the team did. A line like I led the packaging system and the campaign film was directed by someone else tells a hiring manager which part of the job can be handed to you, which a credit-free image never does. Where a studio's rules stop you being specific, describe the problem and your role and leave the client unnamed.
Both, with the site as the copy you control. A resume page on your own domain turns up when somebody searches your name, and a downloadable PDF gives a recruiter something to attach to an internal thread. LinkedIn stays useful for being found in the first place. Keep the two saying the same dates and the same titles, since a mismatch is the sort of thing that gets asked about in an interview.
