15 Services a Top-Tier SEO Marketing Agency Will Offer

Not all SEO services are created equal. Here’s a comprehensive list of services you should look for in any prospective SEO agency. 

1. Understanding Your Company & Goals

A standout SEO marketing agency begins by immersing itself in your company and brand. It seeks to understand your product, target audience, and objectives. This foundational knowledge is crucial for crafting an SEO strategy that resonates with your brand identity and overall company goals.

2. Website Audit

Conducting a thorough website audit is the foundation of a solid SEO strategy. This process involves evaluating your site's current SEO performance, identifying areas for improvement, and detecting any technical issues that could hinder your SEO efforts.

3. Content Analysis

Content is king in the SEO world. Agencies should conduct a comprehensive analysis of your existing content to assess its effectiveness, relevance, and SEO friendliness, and then identify gaps and opportunities to enhance your content strategy.

4. Buyer Personas

Understanding your target audience makes a huge difference when it comes to ranking on the SERP. If you don’t already have them, top-tier SEO agencies develop detailed buyer personas that help tailor your SEO and content strategy to meet the specific needs and preferences of your audience — so your content is always relevant and valuable.

5. Tracking and Analytics

SEO isn’t the place for best guesses. Data should drive decision-making, and a great SEO agency will set up robust tracking and analytics systems to monitor your website's performance, providing insights that guide ongoing strategy adjustments. 

6. Setting Up SEO Tools

The right tools can amplify your SEO efforts. Excellent SEO consultants will equip your team with the latest and greatest tools for keyword research, site analysis, performance tracking, and more, ensuring you have insight into organic search performance and the information necessary to make informed decisions.

7. Technical SEO

Technical SEO is about optimizing the infrastructure of your site. SEO marketing agencies should focus on improving site speed, mobile responsiveness, and overall website architecture to enhance user experience and search engine crawlability.

8. Customized SEO Strategy

An SEO strategy should be just as unique as your company itself, and SEO marketing agencies should understand this. Great agencies create bespoke SEO plans that align with your specific needs, industry trends, and company goals — helping you generate more demand and revenue.

9. Content Marketing

Content marketing and SEO go hand in hand. SEO agencies should help create high-quality, engaging, and SEO-optimized content that resonates with your audience and boosts your search rankings.

10. On-Page SEO

On-page SEO involves optimizing individual web pages to rank higher in search engines — and any SEO expert worth their salt will offer this. On-page SEO includes optimizing copy, HTML source code, images, UX, and more.

11. Link Building

Building a strong backlink profile is vital for SEO success. Agencies should focus on acquiring high-quality backlinks from reputable sources, which boosts your site's authority and search engine rankings.

12. Earned Media

Agencies should help you leverage earned media opportunities to enhance brand visibility, authority, and your backlink profile. This includes strategies like PR, influencer collaborations, and guest porting.

13. Conversion Rate Optimization

Driving traffic to your site is one thing; converting visitors is another. Gold star SEO marketing agencies know how to employ conversion rate optimization techniques to turn your visitors into customers.

14. Growth Marketing Strategy

Incorporating SEO into your overall growth marketing strategy is essential. The best agencies will  integrate your SEO efforts with other growth marketing tactics — like paid marketing and lead generation —  to drive  revenue growth.

How to Measure SEO Success

Wondering what the true indicators of SEO success are? Here’s what metrics to track to your SEO strategy is working:

  • Improved Search Rankings: One of the most direct indicators of SEO success is an improvement in your website's position on search result pages for your targeted keywords.
  • Increased Organic Traffic: A rise in the number of visitors coming to your site through organic search is a clear sign of effective SEO.
  • Quality of Traffic: More traffic is good, but the right traffic is better. Look for an increase in engagement rates, such as longer visit durations and lower bounce rates.
  • Conversion Rates: Effective SEO should lead to higher conversion rates, indicating that the traffic driven to your site is relevant and interested in your product.
  • Lead Generation and New Users: Monitor the increase in leads or new user sign-ups as a result of your SEO efforts. This metric directly correlates to your site’s ability to attract and engage potential customers.
  • Revenue Growth: Track the contribution of SEO to your overall revenue. An increase in revenue from organic traffic signifies that your SEO strategy is not just attracting visitors, but also driving profitable customer action.
  • Keyword Performance: Monitoring how your chosen keywords are ranking and their contribution to traffic and conversions can provide insights into the effectiveness of your keyword strategy.
  • Backlink Profile Growth: An increase in quality backlinks from reputable sites is a strong indicator of improved credibility and authority in your domain.

Remember, SEO is a long-term strategy. Immediate results are rare, so it's important to focus on consistent and gradual improvements over time.

SEO Agency vs. In-House SEO: Which Is Better?

Deciding between an in-house SEO team and an external SEO agency can be tricky. Both options have their merits, and the best choice depends on various factors, including your company's size, budget, and specific SEO needs.

If you’re an established brand that can afford to hire an in-house team, that could work for you. However, with an agency, you can access a diverse team of five or more SEO experts, each specializing in different aspects of SEO, for the same cost as hiring one in-house SEO professional. This not only maximizes your budget but also provides a breadth of expertise that a single individual can seldom match, making it an ideal solution for companies of any size seeking comprehensive SEO strategies without the financial burden of expanding their in-house team.
