MAKING DECISIONS IS IMPACTED BY TYPOGRAPHY.
Thinking of the logos above, it is evident that they have used different font styles; slab, script, serif or sans-serif. They all have one common element, that is they have eye-catching type, each in their own unique way.
Thinking of a flower shop, for example, when someone attempts to create a logo for them the first style the would go to would usually be a script font, which relays elegance playfullness. Sans-serif and Serif would be the secong choices, depending if the flourist wants a more modern or more vintage approach respectively. Yet, very rarely one will see a flower shop with a slab font, mainly used in construction or technology (ex. IBM, Honda, Sony). Such fonts are used to convey strength, stability and rigidity. To use such a logo the flower shop would be passing on such a message ; maybe they specialise in selling big solid trees or stable healthy flowebeds. In any case, it is quite rare.
The important element to remember is that whichever type of font is used it should be relevant and consistent as it will impact the brand in all further marketing endeavours.
