What are good tags to use in my posts?

The first tag can never be changed, so choose it carefully! Tags that mention the subject of the post are best for the first tag — travel, gardening, crypto, food, etc. Sometimes, two such "topic" tags are good, for instance: #food and sushi or recipes.

For posts that are in Spanish, use #spanish as one of the tags (although #english is NOT necessary for any post in English). Posts in German can be tagged #deutsch, and so forth.

After that, consider tagging any communities to which you belong such as #hiveph for those who live in Philippines and #wafrica for folks in West Africa; there may, or may not, be a community for your geographical area. There are also many communities on Discord which you can tag if you are in those communities (#ladiesofhive, #naturalmedicine, and others).

Other good tags would include Tribes and Communities, which will give your post more exposure, such as #palnet and #neoxian, which will accept content on any subject. IF your post relates to investing, you can use #leofinance, but don't use that tag for anything except investing! IF your post is of a creative nature (art, music, sculpting, dance, poetry, writing, etc.), you can use the #creativecoin tag, but only if the post is of a creative nature! For any post that talks about the things that define who you are, you can always use #innerblocks as a tag. If your post is inspirational, thoughtful, or encouraging in nature, WesPhilbin's #thoughtfuldaillypost is a good tag.

Ensure, though, that your tags are relevant to the topic of the post. Tagging unrelated topics is "tag abuse," the same as when someone uses the tag #travel on a post about cooking, or #recipes on a post about investing, etc. Don't do that, but use relevant tags!
