What earns a post its place
It answers a question a real person asked, using facts only your business can supply: your assortment, your prices, your neighborhood, your hours on a holiday weekend. Those facts are yours alone, which is exactly why search engines rank them and assistants quote them.
Esplanda already has the facts
Posts come from the same catalog that orders your stock and forecasts what sells. Drafting "what to bring to a housewarming under $25" means naming the bottles you have in stock this week at that price. See retail inventory management software.
Keep the register you have, or use ours. Esplanda POS is free and keeps every post on live stock and prices; a Square, Clover, Lightspeed or KORONA register connects instead.
