Best 12 SEO Firms

SEO Blog SEO Tools

Increasing brand awareness and attracting customers is the most important task for marketers in every company. To fulfill this goal, the website plays a key role: on it, potential customers can learn about your services, read about the completed work and customer reviews, leave an application and contact you.

One of the most effective online marketing channels is organic traffic from search engines. Therefore, search engines must optimize the website to get to the top of search results and receive free targeted traffic. In other words, it is necessary to perform SEO optimization. This is a complex task, which includes working with the site code, design, and content. SEO firms provide this range of services with their experts in search engine optimization.

What Does An SEO Firm Do?

SEO firms can perform a lot of work on search engine optimization. However, the main duties of an SEO firm include:

  • Website audit, including usability analysis and technical checks
  • Evaluation of content quality and website visibility
  • Analysis of competitors’ websites
  • Development of a content strategy
  • Query clustering and creation of a semantic core
  • SEO content optimization
  • Work on the internal optimization of the website and improvement of usability
  • Interaction with narrow specialists (programmers, copywriters) to implement the promotion strategy
  • Creation of a quality link profile of the website
  • Analytics of SEO promotion results

This isn’t a full list of SEO firm duties, and these are just the main ones. Working with an SEO agency is a bit like riding the train – each one can increase your website’s targeted traffic and organic rankings. Therefore, your main task is to make sure that you have chosen the right SEO firm.
