Comparison of dictionaries

Depending of the word that I will look for and the topic, I look for in one dictionary or another.

 I  try to research definitions of “advertise” from some dictionaries:

From Oxford Dictionary:

·        describe or draw attention to (a product, service, or event) in a public medium in order to promote sales or attendance:

A billboard advertising beer´

·        publicize information about (a vacancy):for every job we advertise we get a hundred applicants:

He advertised for dancers in the trade papers

·         make (a quality or fact) known:Meryl

 Archaic notify (someone) of something:
some prisoners advertised the French of this terrible danger

From Webster Dictionary:

·        to make something known to : 

·        to make publicly and generally known  "advertising" their readiness to make concessions

·        to announce publicly especially by a printed notice or a broadcast

·        to call public attention to especially by emphasizing desirable qualities so as to arouse a desire to buy or patronize 

From Word Reference:

·        to present or praise (goods, a service, etc) to the public, esp in order to encourage sales

·        to make (something, such as a vacancy, article for sale, etc) publicly known, as to possible applicants, buyers, etc: to advertise a job

·        (intransitive) followed by for: to make a public request (for), esp in a newspaper, etc: she advertised for a cook

 All definitions from these dictionaries are very similar but I prefer to use Oxford dictionary because It has good examples of sentences with the word which I am looking for.

However when I checked learnersdictionary I saw more and better examples than on Oxford dictionary.
