Yes continuing to post in a construction tag will allow others to search for it. I'd advise that while construction might be your strength, there are only 40k accounts and most of them are crypto enthusiasts. If you like writing about construction it might be beneficial to make a few posts with different types of construction and get feedback. Like how to mix concrete, or special tips to make it stronger etc. I know of someone else who writes great dental articles, but was frustrated because not many people viewed them. If you can me construction posts funny, interesting and entertaining I think you could carve out a cool niche, but success will probably not be immediate. So fishing would also be a good topic. Even if you aren't making high dollar posts, if you enjoy what you are writing about, connect with others with the same interests, or answer questions, it will be a success. A lot of people are starting with no following so now is the time to be creative and try and fail and see what your unique voice can provide steemit.
