#TravelTuesday can cover a large variety of things for business platforms, not just airlines and transportation authorities (but certainly do use the hashtag if you're in those industries). Follow these couple of tips to maximize your social media strategy.
Large is too niche. Union Metrics advises that you always "combine large hashtags with smaller niche hashtags." For example, if you're using #TravelTuesday, you want to ALSO use #worldtraveler, #globetrotter, #seetheworld, #vacationdays, in order to generate the most keyword searches for your post. Beware of looking spammy, however. Limit it to 3-8 tags.
Hotels, Motels, Tourism. Using the tag #TravelTuesday with your regular tour guide promotions, hotel discounts, or even linked motel discounts will do you wonders. If you're located near/in a city that's hosting a business conference, or just a hot seasonal destination, you want to expand on the ability to sell the last-minute ticket and hotel sales.
