What is an SEO Agency?

An SEO agency, or search engine optimization agency, is a service provider that specializes in improving a website's visibility on search engines like Google or Bing. It uses international SEO, local SEO, and other specialized techniques to enhance the site's ranking in search engine result pages (SERPs), making it easier for potential customers to find. This includes optimizing website content, improving site structure, and building backlinks. The goal is to increase organic traffic and drive more visitors to the website.

What services do SEO companies provide?

SEO services cover many types of search engines, from YouTube to social media platforms. However, they generally refer to the specialized services offered by an agency to optimize your website for Google, which is known for its sophisticated and ever-evolving algorithms. Some firms also focus on eCommerce SEO or SEO for startups.

SEO companies offer these key services:

Keyword research

This is the process of identifying the search terms your target audience uses to find websites similar to yours. The next step is to strategically include the most relevant keywords for your business in your website’s content so that it shows up higher on SERPs.

Seasoned SEO experts use many analysis methods and tools to discover and target the best keywords for your business.

On-page optimization

This involves auditing the current user experience and optimizing on-page elements to ensure:

• Targeting the right keywords both in text and images
• Optimizing title tags and meta descriptions
• Featuring images and other multimedia that are properly sized for fast page loading speed
• Adding components like calls-to-action (CTAs) that increase on-page engagement and session duration
• Developing link-building strategies for increased click-through rates (CTRs)
• And more

Content marketing

By creating high-quality, keyword-optimized content that answers your audience's questions and establishes your authority in the industry, you will develop an excellent content marketing strategy that drives traffic and engagement and builds trust. Blog posts, articles, videos, and infographics that are created with SEO best practices encourage social shares, improve social media marketing, and, in turn, help drive traffic back to your website.

Technical SEO

This is the process of optimizing your website for Google's crawlers, allowing them to interpret and index the web properties.

An SEO agency will perform a technical SEO audit to check if the technical side of your website is on par with best practices. In other words, it will take a set of backend measures that:

• Determine which pages are visible to the search engine and which are hidden
• Ensure that the web architecture is optimized for crawlers
• Identify technical issues that communicate poor web performance to search engines
• And more

Off-page optimization

This involves strategies outside the website that are still aimed at increasing its rankings in search. The key to off-page SEO is link building.

Link building helps boost a website's domain authority and credibility in the search engine's "eyes," which is one of the key factors in rankings.

Website design and usability

An SEO-friendly website design ensures that your web pages are structured for easy crawling and indexing, while also optimizing functionality across all devices — a critical ranking factor for Google.

Pay-per-click (PPC) advertising

While SEO focuses on organic search rankings, paid media and PPC campaigns complement SEO efforts by driving immediate traffic to your website. Paid search ads can target high-value keywords, giving your business more visibility, while your SEO techniques yield organic results for long-term growth. Hence, integrating PPC into SEO supports a well-rounded digital marketing strategy to maximize your online brand presence. Also, understanding how PPC fits into the broader search engine marketing (SEM) strategy can help enhance your overall digital approach.

KPI tracking

Unlike traditional marketing, you can easily track and measure SEO results. An SEO company pays deep attention to analytics and provides its clients with monthly analytical reports on campaign, content, and website performance.

Some of the key metrics it tracks are:

• Traffic sources
• Traffic volume
• Click-through-rates
• Search engine positions
• Qualified leads
• Sales
• Sign-ups
• And more

Competitor analysis

This involves surveying your industry's competitive online landscape, assessing your SEO competition, and using the information gathered to strengthen your website's SEO. It gives insight into the competitors' content strategy, keyword targeting, link profile, and overall SEO techniques.

How much do SEO agencies charge for their services?

SEO agencies typically charge between $1,000 to $5,000 per month for their services, with national campaigns costing $2,000 to over $10,000 per month.

Available pricing structures based on project scope and your business's specific needs include:

• Hourly rate: $100 to $250
• Project-based rate: from $500 for simple projects to $1,000 and above for more complex tasks requiring more resources
• Custom or a la carte services: Tailored services depending on your brand's changing needs (e.g., site speed optimization or SEO audits)

Several factors determine the cost of an SEO campaign, including:

• The service scope
• Business goals
• Your website's size, complexity, and current performance
• Target results and timeframe
• The level of competition within your industry
• The agency's location and experience level

The top 50 SEO agencies on DesignRush charge an average of $106 per hour. 16.4% of these service providers accept small-scale projects with a minimum budget of $1,000. Meanwhile, 0.9% cater to larger, more substantial projects with a minimum investment of $50,000. This allows them to provide advanced SEO solutions and premium support that boost search rankings and drive long-term digital visibility.

How to hire an SEO company?

Consider these steps when hiring an SEO company:

1. Identify your requirements

Define your goals, expectations, and key performance indicators (KPIs), along with the budget parameters to work around while also considering your target ROI.

2. Research potential agency partners

Search for SEO agencies on credible online directories like DesignRush, which cover everything from small business SEO and enterprise SEO to multilingual SEO and curated lists by reputable blogs. From here, build a long list of candidates.

3. Check their website rankings

Are their business sites successfully optimized? Do they rank high in searches for their keywords? If they couldn’t establish a strong online presence for their own brand, it's unlikely that they can assist you in doing so.

4. Look at their certifications and recognitions

Are they a Google Premier Partner? What other affiliations do they have? Have they been acknowledged for excellence in terms of services, strategies, or results?

5. Evaluate their experience and expertise

Evaluate their case studies and client reviews. Their documented SEO work showcases their capabilities to create and launch successful campaigns. Are the goals and metrics clear? Do they state a timeframe for the projects? What do clients have to say about their experience? You can also check the rankings of the brands they promote.

6. Consider their team members

Also, learn about their team size and client ratio. Do they have a diverse workforce with multiple specializations? Do they assign a team to a single client or multiple clients at once? This will help you assess their workload and how they manage their tasks.

7. Shortlist, send RFPs, and arrange interviews

Based on your initial assessments, streamline your candidates to five SEO firms. Then submit detailed SEO requests for proposal (RFPs). After receiving and perusing the custom proposals, schedule interviews to assess if they are a good fit in terms of requirements, services, culture, and values.

8. Inquire about their SEO work and your project

Ask which tools and techniques they use and why and how these will impact their work on your website. Proper SEO isn’t about shortcuts and tricks — instead, it’s rooted in best practices such as identifying valuable keywords, assessing competitors, gathering analytics, and quantifying progress.

9. Choose your SEO agency partner based on the evaluations

Compare the candidates’ proposals, their performance during the meeting, communication skills, and the transparency of payment schemes. Bring a final decision and discuss the contracts.

Our experts have handpicked the top six SEO agencies ranked by best results, each company showcasing a variety of impressive case studies in their portfolios. Take a look at some of their most stellar projects:

Searchbloom

ShirtSpace, an online apparel shop, approached Searchbloom with a pressing issue — its website was plagued by hundreds of thousands of URLs hosting duplicate content. This led to crawl budget problems and a lack of relevant content on most web pages. The site's architecture and URL structure also deviated from best practices, as products were not properly subcategorized.

Searchbloom solved the website's authority issues through diverse link acquisition tactics, boosting referring domains from 303 to over 860. It conducted internal and referring domain audits, removed low-quality links, and reclaimed broken inbound links. To improve relevance, it developed content briefs and optimized titles, descriptions, and headings.

The agency performed a massive link cleanup of over 15,000 backlinking domains to identify which potentially hinder rankings.
