If someone's Instagram, X, and LinkedIn all link to different sites, I'd assume they're experimenting with multiple identities or audiences online. It could mean they're running separate projects, side hustles, or testing where their traffic converts best across platforms. It also signals a lack of unified personal branding, or maybe just intentional segmentation between professional and casual personas. From a quick glance, I'd wonder if they want to be discovered differently depending on where you find them.
