Matrix

Matrix is the Enterprise or Agency level search engine optimization platform formerly developed and owned by Barcelona based company Intelligent SEO which was recently (Jan. 2014) acquired by American company Insequent, Inc to expand their offerings. Matrix presents the full panoply of SEO features, like search ranking and tracking, keyword and backlink monitoring and suggestions, site audit, competitor tracking and head-to-head comparison with the home team, also a landing page generator, and many reporting features, with the capability of presenting and forecasting the optimal SEO approach, organic and PPC, for your enterprise or (if you're an agency) your clients' enterprises. A free 30-day trial is fully featured sans user management and custom reports, after which pricing begins at $115 per month with the Audit & Tracking edition. The Business pack, for $315 per month, expands with the landing page generator and more advanced roadmapping and forecasting, as well as greater volume of site management and keyword research, and more users. Finally, For Agencies, is the edition eponymously directed at Agencies for $625, and includes custom (white label) reporting. Should this be too much software, Insequent Inc also offers Leadzer, an SEO platform also developed originally by Intelligent SEO and acquired by Insequent in 2014, for a leaner, SMB-targeted offering.
