Profiles
15 providers tagged

about.me
Value4about.me lets people publish a simple public profile page at an about.me username URL. The backlink opportunity is a profile button or social/website link, not an editorial citation, and inspected public examples mark those outbound links as nofollow.

Discogs
Value4Discogs is a community-built music database and marketplace for physical releases, used by collectors, sellers, DJs, labels, and artists. A public user profile can display an external website link, which makes it a simple profile-citation opportunity for music-related brands.
Gravatar
Value5Gravatar is Automattic's public avatar and profile service for people who want one identity across WordPress and other sites. A Gravatar profile can include a visible Links section, so it works as a simple nofollow profile citation or link-in-bio page rather than a high-equity SEO backlink. Its real leverage is that the same profile follows your email address onto every WordPress, WordPress.com and bbPress site that shows avatars.
Facebook Pages
Value5Facebook Pages let businesses, creators, organisations, and local brands publish a public presence on facebook.com. A Page can show one or more website links in its About/contact information, but Facebook routes those links through its own linkshim and marks them nofollow.

Goodreads
Value11Goodreads is a book discovery and reader community owned by Amazon. Verified authors can claim an author profile and add an official website link that appears on a public Goodreads author page.

LiveJournal
Value5LiveJournal is an older blogging and community platform where public journals and profile pages can include external website links. The most predictable backlink path is the profile Website field, which renders as a direct public link on the user's LiveJournal profile.

Mixcloud
Value4Mixcloud is an audio streaming platform for DJs, radio stations, labels, podcasters, and music communities. A public creator profile can include external links in the profile text, which makes it useful for branded discovery and referral traffic rather than clean dofollow SEO value.

MyAnimeList
Value4MyAnimeList is an anime and manga cataloging community with public user profiles. The safest backlink path is the profile sidebar's website/social link area, which appears on public profile pages under "Also Available at."

Habr Q&A
Value5Habr Q&A is a Russian-language question-and-answer community for IT specialists. The practical backlink path is a public profile website link, not promotional questions or answers.
ReverbNation
Value3ReverbNation is a music-promotion platform where artists can publish public profiles, songs, events, and industry-opportunity submissions. The practical backlink path is the public artist profile link area, where an artist can list an official website alongside other web links.

Smashwords
Value4Smashwords is an ebook store operated by Draft2Digital. A registered user can create a public Smashwords profile and add a personal website, blog, or social link; the resulting external profile link is direct but explicitly nofollow.
SoundCloud
Value4SoundCloud is an audio hosting and discovery platform for musicians, labels, podcasters, and other creators. A public creator profile can include website and social-profile links, but SoundCloud routes external URLs through its gate.sc redirector and marks profile links as nofollow/UGC.
Twitch
Value4Twitch is a livestreaming platform where creators publish channel pages with bios, social links, and custom About panels. The practical backlink route is a creator profile link, not an editorial placement.
Sony Electronics Community
Value4Sony Electronics Community is Sony's public support community for consumer electronics questions, answers, and member profiles. The backlink opportunity is a conservative profile/About Me URL, not a place to drop promotional support posts.
Wattpad
Value5Wattpad is a reading and writing community where authors and readers publish stories and maintain public profiles. The practical backlink path is the profile website field, which can point to an author site, book landing page, portfolio, or related project.
