Have questions about hiring an SEO company in the United States? We've answered some of the most common questions buyers have about hiring a service provider.
An SEO firm is a third-party service provider that primarily specializes in helping businesses execute effective search engine optimization strategies. Their services aim to help websites drive organic traffic, boost revenue, and attract new customers. They do this through keyword research, content creation, building backlinks, optimizing the technical performance of your website, and more. These strategies help optimize your website for crawlers.
Several factors go into determining the cost of hiring an SEO company, including the duration of the project, the scope, the agency's location, and their experience. Typically these companies will work with you to provide an estimate based on your desired outcome and budget limitations, but you should probably expect to pay $10,000–$50,000. Additionally, businesses should consider whether they want to work with an agency that offers mobile optimization, local SEO, and content creation because they may incur additional costs. Learn more about how much it costs to hire an SEO agency in Clutch's SEO Pricing Guide.
Understanding your website is key to knowing which partner you’ll need. Usually, larger websites require more work, thus requiring a team or an SEO firm. In contrast, simpler websites tend to need less work and a freelancer may suffice. Read more about this difference in When to Hire a Freelance SEO vs. Agency.
When selecting an SEO firm, evaluating their background and experience is important. If you’re looking for an agency with a proven track record of improving rankings, growing backlinks, and increasing traffic. Inquire about the scope of services they offer and ask for examples of previous projects they have managed. It is also beneficial to choose one that offers additional services, such as data analysis, social media, and public relations.
