How many keywords are ideal for the META keywords tag

Question

I know not many of us have direct knowledge of the algorithms behind different search engines, but in your experience, does the number and order of keywords have any effect? Is it better to have fewer or more keywords, and are the keywords that are listed first given higher priority?

Answer 1

actually there is no official limit on this you can have as many number of meta keywords
each seacxrh engine sets their own rule on this
but to set an optimum number for all advantage
Page title – 70 characters
Meta description – 160 characters
Meta keywords – No more than 10 keyword phrases
