    Use:

    SELECT t.id,
           t.keyword,
           t.count,
           t.date
      FROM TABLE t
      JOIN (SELECT t.keyword,
                   MAX(t.date) 'max_date'
              FROM TABLE t
             WHERE t.count IS NOT NULL
          GROUP BY t.keyword) x ON x.keyword = t.keyword
                               AND x.max_date = t.date
