The process commenced with an initial consultation call to discuss our requirements and objectives. Subsequently, a detailed plan was presented, with a focus on on-site optimization and site speed. An account manager was then designated, who delivered customized reports and benchmarks. The results achieved thus far have been exceptional. Since the initial optimization took place, and thereafter focusing on off-site activities, we’ve been able to achieve 630 keywords on the first page. The experience has been remarkably smooth and effective.

Since engaging 9thCO Inc, our department has experienced a significant increase in user satisfaction. With the support of the new system development, our senior members have had the opportunity to concentrate on more account management as opposed to resource conflict resolution. Consequently, our production output has witnessed a considerable upswing.
