Rate parity, search engine optimisation, keyword buying, distribution strategies - themes that many a hotel owner or intermediary grapple over every day.
The life of the hotel sector marketer or distribution strategist is not an easy one, and doesn't show signs of getting any smoother any time soon.

The aforementioned rate parity drama is one such issue, on a grand scale, another is the introduction of same-day, mobile booking applications.
Metasearch's rise in recent years to become more than just a search tool (in-app bookings, etc) deserves to be mentioned in the same breath as other disruptive influences on the hotel marketing discipline.
