Hire large US SEO agencies when you need multiple capabilities under one roof, such as technical SEO, content development, PR, and paid media. Hire specialized firms when SEO is your main growth channel, and you have defined needs, such as eCommerce optimization.
Often, large SEO agencies in the US provide comprehensive digital marketing services, making them a practical option for businesses without internal marketing teams or for brands running extensive multi-channel campaigns that require close coordination.
The drawback is that the focus of large agencies is divided across the different channels, which may be executed by junior staff. This means that there is a higher chance of mistakes and issues going unnoticed.
Conversely, specialized SEO companies in the USA provide direct access to senior marketers and offer in-depth expertise in a vertical or region. As such, it best suits businesses that rely on organic search as their primary customer acquisition channel.
However, you will need an internal team or hire a different agency to manage other marketing channels.
Searchbloom breaks down the most common specialized SEO agencies in the USA:
- Local and multi-location SEO companies in the US focus on fine-tuning location data, reviews, and optimizing Google Business Profiles and map presence as part of geotargeting efforts.
- National SEO agencies prioritize content strategy, internal linking, and link building initiatives to scale authority and improve nationwide search rankings.
- eCommerce SEO firms manage catalogs, feeds, schema, faceted navigation, and parameterized URLs, as part of a broader eCommerce marketing strategy, often with local inventory in the mix to support both organic discovery and conversions.
