Search Engines use multiple factors to index sites. Each factor has a different weighting that is determined by the algorithm. And each search engine uses a different algorithm, which is changed up regularly updated. This explains why different search engines return different results.

At JPC we review and re-engineer all the known factors that affect the listing
of a site in the major Search Engines. We make adjustments and modifications
to remain current with the changes and known best practices. And we use only ethical techniques to make sure your site is not penalized or de-listed because
of anything we have done.

Re-engineering your site is another important technique to achieve the highest listing possible.
