What are the tools which assist to do increase in LFL sales ?

 first (like for like) used to compare a growth in sales over a period of time just like the comparison of the current year's sales with the sales of the previous year

So the tools which assist to do increase in LFL sales :

1- comparison has to be done on equal terms

2- comparison does not include any entities that may affect the sales.

3-  comparison should not be considered Any new product launch or a change in marketing strategies

Like for like (LFL) growth is a measure of growth in sales, adjusted for new or divested businesses. This is a widely used indicator of retailers' current trading performance. The adjustment is important in businesses that show a significant dynamic of expansion, disposals or closures. You need a little tactics here according to me. Bye.
