Questions & Buyer Guides
What's the best way to use tagging for your notes? Practical habits for building a tag system that actually improves retrieval — vocabulary size, application timing, and maintenance.
Short answer: Keep the tag vocabulary small (15-30 tags), apply tags at the moment you write the note rather than retroactively, mix topic tags with workflow-state tags, and periodically consolidate near-duplicate or unused tags. The goal is reliable retrieval with minimal overhead — not comprehensive categorization.
Start from actual retrieval needs, not anticipated ones. Rather than designing a comprehensive taxonomy upfront, look at what you've actually needed to find in your notes over the past month or two. What categories would have helped? Those are your starting tags.
Aim for 15-30 tags total. This range is large enough to cover meaningful categories and small enough to remember without a reference list. Systems with hundreds of tags become unwieldy — you forget which tags exist, create near-duplicates, and apply them inconsistently.
Include both topic and workflow tags.
Topic tags represent subject matter: #client-work, #hiring, #product-strategy, #personal-finance. These help you find notes about a specific area regardless of when you wrote them.
Workflow tags represent status or relationship to the note: #needs-followup, #draft, #decision, #reference, #waiting-on-response. These help you find notes based on what you need to do with them, which topic tags and search can't capture.
Most useful tag systems have roughly equal numbers of each type.
At the moment of writing, not later. The context for why a note matters and what categories it belongs to is clearest when you're writing it. Deferring tagging to a later "organization session" both delays the benefit (untagged notes aren't filterable in the meantime) and produces less accurate tagging (you've forgotten some of the nuance by the time you get to it).
As part of the note-creation habit, not a separate step. If your note-taking tool supports quick tag entry (typing # and a tag name inline, or a dedicated tag field), make applying 1-3 relevant tags a routine final step before saving a note — as automatic as adding a title.
Don't force tags where none clearly apply. Not every note needs a tag. If a note doesn't fit any of your existing categories and doesn't seem to need cross-cutting retrieval, leave it untagged rather than creating a new tag for a one-off case.
Ask: "How might I want to find this note later?" Not "what is this note about" in an exhaustive sense, but specifically what future search or filter would you use to retrieve it. This framing keeps tagging focused on retrieval rather than comprehensive labeling.
Prefer existing tags over creating new ones. Before creating a new tag, check whether an existing tag already covers the need. Tag proliferation (many near-duplicate or overly specific tags) undermines the reliability of "show me everything tagged X" because related content gets split across similar-but-different tags.
Limit to 2-4 tags per note. Beyond this, you're likely tagging for completeness rather than genuine retrieval need. A note doesn't need to be tagged with every conceivably related category — just the ones you'd actually filter by.
Quarterly tag review. Every few months, scan your full tag list. Look for:
#idea and #ideas)Merge rather than delete when consolidating. Most note-taking tools support renaming a tag, which effectively merges it into another tag name across all notes that use it. Use this to consolidate near-duplicates rather than manually re-tagging notes.
Retire tags that reflect closed chapters. A tag for a completed project or a former role can be archived (or simply left alone, unused) rather than actively maintained. Not every tag needs to remain part of your active vocabulary indefinitely.
Tags plus folders (or their equivalent). Use folders or a similar primary structure for the main organizational context (by project, by area of responsibility), and tags for the cross-cutting categories that don't fit neatly into that primary structure. They're complementary, not competing.
Tags plus search. For tools with strong search capabilities, tags are most valuable for the narrower purpose of guaranteed-complete filtering (workflow states, explicit categories) rather than general topical findability, which search increasingly handles well on its own.
Tags plus a "hub" note. Some practitioners maintain a single note per major tag that links to or summarizes the tagged notes, providing a curated entry point beyond the raw filtered list. This is optional and adds value primarily for your most frequently-referenced categories.
Don't build the tag taxonomy before you have notes. A comprehensive tagging system designed in the abstract, before you've experienced what you actually need to retrieve, tends to not match your real usage patterns. Build the vocabulary from experience.
Don't create nested tag hierarchies unless you've hit a specific limitation. Flat tags are simpler to apply and maintain. Nested or hierarchical tags add complexity that's only justified once you've experienced a specific retrieval problem that flat tags don't solve.
Don't tag retroactively as a large project. Going back through hundreds of old, untagged notes to apply a new tag system is a significant time investment with uncertain payoff. Apply the new system going forward; retroactively tag only the specific old notes you find yourself needing.
WebSnips supports the same tagging approach for captured web content: a handful of tags applied at the moment of clipping, combining topic categories with workflow states relevant to how you plan to use the saved content (#to-review, #competitor-research, #swipe-file).
Using a consistent tag vocabulary across both your notes and your WebSnips captures means a single tag search or filter surfaces relevant material from both — your own thinking and the web content that informed it — without needing to search two separate systems with different categorization logic.
Should I use single-word tags or multi-word phrases?
Single words or hyphenated short phrases (#needs-followup rather than #needs follow up) are generally easier to type consistently and less prone to variation (#follow-up vs #followup vs #follow up fragmenting what should be one category).
How do I handle tags that apply to a huge portion of my notes? If a tag is applied to a very large fraction of your notes, it's probably too broad to be useful for filtering. Consider whether it should be split into more specific sub-categories, or whether it's actually not adding retrieval value and could be dropped.
Is it worth color-coding tags if my tool supports it? Only if you find visual scanning genuinely useful for your workflow. For most people, the retrieval benefit of tags comes from filtering and search, not visual browsing, making color-coding a nice-to-have rather than essential.
The best way to use tagging: keep the vocabulary small (15-30 tags), apply tags at the moment of writing, mix topic and workflow-state tags, limit to 2-4 tags per note, and review periodically to consolidate and retire tags that have drifted from usefulness.
This lightweight, consistent approach delivers the real retrieval benefit of tagging without the maintenance burden of an elaborate taxonomy.
