Their client-centric approach involves understanding conversion goals, creating a tailored SaaS SEO strategy, implementing the plan, monitoring SEO performance, and making improvements based on data.

Omniscient’s consultative approach makes them popular across big established companies. It also helps that they pay attention to how their work potentially augments other marketing channels and SEO campaigns.

However, their pricing is on the expensive side, making it difficult for small SaaS companies to engage them.

Key SEO services:

• SaaS SEO Strategy: Build a data-driven content strategy for you using search data, and search intent analysis.
• Content Creation: Create high-quality, strategic content that matches your distinct brand style and is customized to your business objectives.

• Link Building: Create a digital PR strategy including link building to support your marketing goals.

Approach:

Omniscient follows what it calls the Barbell Content Strategy.

With this strategy, they target SEO topics across all stages of the buyer journey—awareness, action, and decision.

For each stage, Omniscient creates two kinds of content:

• 90% product-led content, which explains the product value proposition
• And 10% buzzworthy content that attracts backlinks, attention, social shares, partnerships, or connections.

Together, both these types of content combine to build topical and domain authority.

Buzzworthy content generates PR and attracts customers who are not yet in the market for a solution. And product-led content helps convert those who are looking for a solution into paying customers.
