Semrush is an all-in-one digital marketing platform covering SEO, paid search, social media, and content marketing. Its keyword research, site audit, competitor analysis, and position tracking tools are used by marketing teams globally. Semrush is particularly strong for paid search competitive intelligence — its ad research features show which keywords competitors bid on and what ad copy they run. The Semrush SEO Writing Assistant WordPress plugin provides real-time content scoring inside the WordPress editor, checking SEO, readability, tone, and originality simultaneously. Semrush integrates with Yoast SEO for keyword suggestions inside the post editor. Plans start at $139.95/month.
B2B marketing teams managing both organic and paid search benefit from Semrush's unified view of competitor performance across both channels. Understanding what ad copy competitors run for the same B2B buyer-intent keywords allows teams to differentiate their own messaging. The SEO Writing Assistant plugin brings real-time content scoring into WordPress, helping content teams optimise copy while writing rather than retroactively.
