Why a visited page can still open#
A website does not have to live only on the network. Many sites can be installed on a phone much like an app, and once a visitor has opened the site, the phone keeps a copy of the pages it has already seen. That copy is what lets the site open again when there is no signal, such as in a basement car park, a lift, or a tunnel under the street.
For a shop owner this matters because customers often look up a shop while they are already on the move. A person who loaded your page on the walk from the station may later want to check your opening hours or your address with no bars on the screen. A page that has been visited before can still answer that question. A page that has never been visited cannot, so the first visit is the one that counts.
What offline pages cannot do#
It helps to be exact about the limits. An offline copy shows what was saved at the last visit. It cannot show news that changed after that visit, and it cannot send a message or load anything new until the connection returns. Anything that needs a live answer from a server will wait for a signal. A map tile that was never loaded will not appear by magic either.
So an owner should think of the offline copy as a snapshot. Keep the important details simple and accurate, such as the address, the hours and the way to find the door, because those are the parts a visitor is most likely to read from memory of an earlier visit. Thai rules limit how cannabis may be advertised, so check your plans with a lawyer before any page goes live.
Directions from the nearest station#
Many customers arrive by train, so a useful page gives directions from the nearest BTS, MRT or Airport Rail Link station. The distance is worked out from map data, and the walk time is an estimate. The estimate takes the straight-line distance and multiplies it by 1.3 to allow for streets that do not run in a straight line, then divides by a walking pace of 75 metres a minute. The result is a rough guide, not a promise.
Because the figure is an estimate, it is worth saying so on the page and checking it yourself by walking the route. A short note about which exit to use, and which side of the road the shop sits on, often helps more than a precise minute count. Keep the wording plain so that a visitor who reads it on a crowded platform can act on it straight away.
Checking the page before you publish#
Before a page goes live, test the things a customer will actually do. Open it on a phone, switch the signal off, and see what still appears. Then check that the transit directions match what you see when you walk the route yourself. Small errors in a station exit or a street name are easy to miss from a desk and easy for a visitor to notice.
Finally, keep a record of what the page says and when it was last reviewed, so that you remember to update it when hours or details change. This is general good practice for any website, and it is a sensible habit to keep for DISPO and SISO Labs pages alike. Before you finish, check your wording with a lawyer, since Thai rules limit how cannabis may be advertised.
