How to ensure effective internal links in your tour business website

Ensure meaningful link labels
Everything on your site should be consistent: your headings, field labels, buttons, etc. … You need to ensure that the color of your link text contrasts.
Apply text rather than images
With the current CSS capabilities in most web browsers, it is good design practice to use actual text that is styled with CSS rather than image-based text
Add clickability cues (underline, colors, symbols)
Cues that can be used to indicate the clickability of an item include color, underlining, bullets, and arrows. Make clickable elements obvious to users so they don’t need to ponder the meaning of design elements.
