Whether you need to seal the tile, the grout, or both depends entirely on the materials you are working with.
Builders often skip sealing grout to cut costs, save time, and avoid returning to the job site. Additionally, many modern polymer-modified grouts are stain-resistant, and sealing un-cured grout can trap moisture. Some installers even use it as an upsell or exclude it because sealing can leave a hazy film on certain tiles.
The best grout for Saltillo (terracotta) tile is a heavy-duty, sanded Portland cement grout formulated explicitly for wide joints (typically 1/2 to 114 inches).

Bleach can also weaken grout and damage any sealer that's been applied. Over time, bleach makes grout more porous, which means it gets dirty even faster. Why to avoid: Like bleach, ammonia strips away protective sealers. It can also discolor grout and weaken the integrity of the grout over time.
Let the grout set for 15 to 30 minutes and then begin gently wiping off the excess grout with a clean, damp sponge. Rinse the sponge frequently, using one bucket for getting the excess grout off the sponge and the other for re-dampening the sponge.
