Widget links come bundled with something another site embeds: a badge, a calculator, a chart, a status indicator or an infographic embed code. Each installation creates a backlink, which made widgets a popular link building tactic. Google's spam policies name keyword-rich, hidden or low-quality links in distributed widgets as link spam, and Google advises using nofollow on widget links that are not purely editorial.
Why widgets became a link tactic
A widget is useful content that spreads itself. If the embed code includes a link, every site that installs it links back. When the link uses the creator's brand name and the site owner can see and edit it, this is little different from attribution. The problem arose when widgets carried hidden or keyword-stuffed links the installing site never chose to give.
Google's position
Google treats links in widely distributed widgets as one of the link spam examples in its policies. Its long-standing advice is to qualify widget links with nofollow, particularly if they use keyword anchors or the site owner cannot easily see or control them. Brand-name attribution that the installing site can change is the safer pattern.

SaaS companies often produce embeddable things: review platform badges, uptime status widgets, cost calculators, comparison charts, "verified on" seals and customer award badges. Each is fine as a product feature. Design the embed so the link is visible, uses the brand name, and is easy to remove.
Example
A salary calculator embed
An illustrative HR analytics company, Payridge, offers a free salary range calculator that HR blogs can embed. The embed shows a small "Data by Payridge" credit with a nofollow link. Blogs that find the data useful still often write about it and link to the full report in their own words, which gives Payridge editorial links alongside the embeds.
Common mistakes
Hiding links in widget code
Links the installing site cannot see or control are exactly what Google's policy describes.
Using keyword anchors in badges
A badge reading "top-rated payroll software" linked to your pricing page creates a manipulative anchor pattern across every site that installs it.
Questions
Badges distributed by review platforms usually link to the platform, not to you. The risk falls on whoever distributes the widget and controls its link.
