Hashtags used to be sold as essential, a magic key that unlocked discovery, algorithmic favour, and reach far beyond your own following. For architecture, interiors, product design and art brands, that promise mattered: a well-placed #InteriorDesign or #ArchitecturePhotography could put a portfolio in front of an audience that had never heard of the studio. The platforms have changed a great deal, and so has the honest answer to whether hashtags still do that job.

From Discovery Tool to Afterthought

Hashtags emerged as a literal indexing system, a way for Instagram and Twitter to sort an unsorted feed. Tag a post correctly and it entered a searchable stream, giving smaller accounts a genuine route to new eyes. That era is largely over. Feed algorithms now read images, captions, watch time, saves and shares directly, and rank content on relevance signals far richer than a tag. What I see across the accounts I manage is that tags now barely move a post: the same work performs much the same with or without them. For design-led brands, this means the tag is no longer doing the heavy lifting it once did, the content, and how people behave around it, is.

Hashtags didn’t disappear, they were quietly demoted.

I used to build long tag sets for interiors and architecture accounts and defend them in planning meetings. I don’t any more. What changed my mind was watching where saves and shares came from: almost always a strong first line and an image worth keeping, almost never a tag. The work tags still do is narrow, and I would rather say that plainly than keep charging for a habit.

Where They Still Earn Their Place, and Where They Don’t

The honest position sits between “essential” and “irrelevant.” Hashtags no longer meaningfully drive broad discovery, and stacking thirty tags under a beautifully shot interior does nothing for reach and quietly signals a dated strategy. But they haven’t become useless, their value has simply narrowed and specialised.

  • Niche communities: tags tied to specific design movements, materials, or regional scenes (#JapandiDesign, #BrutalistArchitecture) still connect work with genuinely interested, high-intent audiences who actively browse them.
  • Campaign and event tracking: a branded or project-specific tag remains one of the cleanest ways to gather, measure and showcase user-generated content around a launch, exhibition or collaboration.
  • Platform search behaviour: on Pinterest and TikTok in particular, tags still function closer to keywords, feeding into search rather than pure feed ranking.
  • Broad, generic reach: #Design, #Art, #Architecture and their like do almost nothing now; they’re crowded, untargeted, and ignored by the algorithm.

The adaptation, then, isn’t abandonment, it’s precision. Treat hashtags as a light, deliberate layer rather than a growth mechanism: three to five well-chosen tags per post, selected for community relevance or campaign tracking rather than volume. Direct the real strategic effort to what algorithms actually weigh, strong opening captions, imagery worth saving, consistent posting rhythm, and genuine engagement.

In Short

Hashtags haven’t vanished, but their job has changed: from discovery engine to a narrow, useful tool for niche visibility and campaign measurement. For a brand built on craft and precision, that’s a fitting shift: fewer tags, chosen with more intention, doing quieter but more honest work.
