  • What is SEO marketing?

    SEO stands for search engine optimization. It's one component of digital marketing that's designed to help websites get found by people in search engines, such as Google. Key components of SEO include, but aren't limited to, keywords, quality content that's relevant to common searches, meta tags, backlinks, and page performance.

    Keywords can include the primary search term someone is likely to use plus semantic phrases people would naturally use when talking about the topic at hand. Good SEO helps search engines, such as Google, know that a site has content that is relevant for the searcher's needs.

  • What is an SEO agency?

    An SEO agency is a business that specializes in supporting strong SEO on and off websites for other brands. SEO agencies can handle a variety of tasks, including creating or hiring out content, conducting keyword research or site audits, building backlinks, enhancing site performance, or completing competitor research.

  • How much is SEO marketing?

    The cost of SEO depends on services and fee structure. SEO experts might charge up to $130 per hour, but clients can often save money by paying a monthly retainer. With a retainer, clients pay, on average, $500 to $5,000 or more per month to engage an agency, depending on the scope of the SEO project and the skill and experience of the SEO agency team. It’s also important to note that clients get the benefit of core services and may buy other services a la carte.

  • What should I look for in an SEO agency?

    What businesses need in an SEO agency depends on their unique requirements. But some common traits to look for include:

    • Knowledge of search engine optimization and online marketing in general
    • Processes that ensure the agency keeps up with SEO trends, including changes to Google algorithms
    • Options for a wide range of services, including content creation, backlink creation, keyword analysis, and page performance auditing
    • A transparent fee structure that's easy to understand
    • The type of customer service that works for the business; options might include a dedicated rep, a team that can be reached via chat or email, or automated self-serve options
  • What is Local SEO marketing?

    Local SEO marketing refers to SEO efforts directed specifically at searches with local intent. If someone wants to find out about the type of birds in the arctic, Google is likely to serve up the site with the best possible information. Conversely, if someone wants to find out about dentists in Dallas, Google specifically looks for sites that look like they're about local dental services in the Dallas area. Components of local SEO include:

    • Claiming appropriate business listings for citation strength
    • Ensuring schema is marked up on a site appropriately and matches other citations
    • Understanding the keywords local searchers use
    • Creating content specifically relevant to local users
  • What is SEO ranking?

    SEO ranking refers to how high a page is listed on the search results. If someone searches "Coca Cola," for example, is the first page in the listings. The Coca Cola website also has the next three top listings because it has such strong authority for this word. The fifth page down is the Wikipedia entry on the topic.
