Fresh And Unique Content IS majer Ranking  Factor

[SEO]

You mean major. I see.

[MSL]

Fresh And Unique Content IS majer Ranking  Factor

The right way to say it is "Fresh and unique content is..." (no more than 1 capital letter, i. e. the one at the beginning of the sentence); "major" (not "majer"); "ranking factor." (no capital letters and a full stop/a period at the end of the sentence.)
 Please, try to type correctly in English.
