Constant Contact's top 10 neighbors span marketing publications, political figures, and news journalists — a mix that reflects no single dominant cluster but a broad, politically engaged professional audience.

The shape is flat: scores run from 0.90 (Social Media Examiner) down to 0.89 (Consumer Reports), a range of just 0.01 across ten neighbors. No single entity pulls away from the pack. Within that band, the subcategory composition is notably split. Three neighbors are marketing-adjacent: Social Media Examiner (0.90, Websites), HubSpot (0.90, Technology), and Search Engine Land (0.89, Blogs). But the remaining seven are drawn from politics and civic life: Ann Handley (0.90, Authors), Fred Guttenberg (0.90, Activists), The Lincoln Project (0.90, Political Groups), Chris Murphy (0.89, Politicians), Jill Biden (0.89, Government Officials), Daniel Dale (0.89, Journalists), and Consumer Reports (0.89, Websites). Constant Contact is the only B2B brand in the top 10; Moz, also subcategorized as B2B, does not appear until further down the broader graph.

The flat shape with this particular mix suggests an audience that is simultaneously professionally oriented toward digital marketing and heavily engaged with political and journalistic content — two distinct interest clusters compressed into a single, undifferentiated similarity band.
