Why Work With a WordPress SEO Agency?

If you use WordPress, working with a digital marketing agency that is well-versed in the software makes sense. There are many benefits to partnering up with a WordPress SEO agency:

    • High level of WordPress experience: Every content management platform is unique in how it’s laid out and the quirks that come with it. Experienced developers and marketers know how to navigate WordPress software and use SEO plug-ins and themes to level up your website.
    • Trend recommendations: Popular search engines frequently update their algorithms and guidelines, as Google did with its E-E-A-T update, so it’s beneficial to have a team of SEO experts who stay on top of trends to ensure your content is still relevant and gaining traffic.
    • Safety and security: You’re in excellent hands with those who follow updated SEO best practices and make sure your website won’t be penalized by Google following an update. WordPress experts also know which plug-ins to use and which to avoid that could compromise site security.
    • Campaign reporting: A WordPress SEO agency will typically provide thorough reports on website performance and suggest improvements as needed. These reports provide concrete data to support important business decisions, such as funding for marketing campaigns.

Working with an SEO agency specializing in your CMS avoids teaching an external team about any WordPress niches or how-tos.

Choosing a WordPress Agency

While each agency specializes in WordPress, how do you know which one to choose? The following factors can help you decide which agency suits your needs best.

  • Assess their industry leadership: Research how long an agency has been in the industry and the type and quality of clients they work with. For example, Siege Media specializes in fintech, SaaS, and e-commerce. Confirm the agency has experience working with clients in your niche industry.
  • Verify their adaptability: Be certain that the agencies you’re looking at keep up to date with these trends and account for them in their overall SEO strategy. For example, any modern agency should have a firm understanding of how GEO actually works. Siege Media offers a framework for GEO, helping you build visibility in LLMs and AIOs.
  • Research customer reviews: Customer testimonials look at current and former client relationships with agencies. Most agencies include testimonials on their website. You can also find reviews and ratings on Google from past clients. Siege Media, for example, has dozens of public, verified client reviews that aggregate to a near-perfect 4.9/5 rating.
  • Check out case studies: While reviews give a brief overview of an agency, customer stories provide more details about what an agency has achieved for its clients. A reputable agency should include several customer stories on its website. Siege’s catalog of case studies is over 75-strong and growing.

After narrowing down your list of agencies, get in touch with them. Most agencies will provide a free quote and website audit. This gives you more insight into whether or not the agency is the right fit for your company.
