    Firestorm SEM (opens in a new tab)

    Business Transformation Through SEO and PPC.

    No verified reviews yet

    Location: King of Prussia, Pennsylvania, United States

    Unclaimed

    Why #1: 5.0 from 2 published Google reviews.

    Firestorm SEM suits a B2B company that wins work through enquiries rather than a checkout, offering a narrow, search only route: B2B is first of the two industries on its profile, ahead of ecommerce. The fit rests on combining PPC, which reaches buyers already looking for a supplier, with content and link building that keep a firm visible across a longer sales cycle. The King of Prussia agency, running since 2011 with a team of 1 to 9, spreads ten declared services evenly, including SEO, AI SEO and GEO, local SEO and Amazon marketing. Web design and social media are absent, so a B2B firm needing a new site or LinkedIn activity would source those elsewhere. Rankyfy measured its organic traffic rising from 11,240 to 16,070 visits over 12 months, scoring 54.8 on reviews at 29 of 40 and visibility at 20 of 25. Projects from $2,500, hourly rates not disclosed.
