Search engine optimization, more commonly known as SEO, is an important component of building a strong digital presence and connecting with more potential customers. It refers to the process of enhancing a website's performance on search engines such as Google, Yahoo, and Bing. With common tactics such as local SEO, link building, and content creation, SEO is a multidisciplinary practice that mainly aims to help businesses appear when customers look up relevant keywords

Basically, SEO is split into three major categories — on-page, off-page, and technical SEO. The first one, on-page or on-site SEO, focuses on optimizing websites and their content to become more visible for search engines. It maximizes techniques such as optimizing internal links, URLs, and title tags to boost organic traffic.

Meanwhile, off-page leans more towards activities and tactics off of a website such as link building, managing branded searches, and content marketing. Technical SEO, on the other hand, is centered on more advanced tactics and different aspects such as improving site speed, supporting user experience, and working on structured data.

Aside from the three main types of SEO, full-service SEO agencies typically offer the following services:

3. Website Audit: The method of evaluating and assessing how websites perform, identifying errors that hinder the website’s performance and ranking on search engines. It usually covers technical aspects such as website crawlability and indexing.
4. Content Creation: It is a creative and strategic process of creating compelling content that attracts target users through search engines. SEO content includes product pages, blogs, shortlists, and infographics.
5. Monitoring and Reporting: Refers to consistently monitoring and observing the performance of SEO campaigns, gathering insights by assessing key metrics and reporting for transparency. Monitoring is important to ensure that the business gets the optimal return on investment (ROI).

What to Look for in an SEO Firm?

Before you hire a SEO partner for your project it's important to do your due diligence and carefully scrutinize respective firms. Here are some factors to consider when looking for a full-service SEO firm:

1. Portfolio & Expertise
2. Communication Style
3. Geographic Location
4. Budget

Portfolio & Expertise

Essentially, an SEO provider's portfolio is their resume that showcases their experience and success working on similar projects. Reviewing their portfolios gives you an insight into how they perform and how well they deliver on their partnerships.

Additionally, assessing their portfolio will give you an idea of the scope of services and how well they execute those services. Of course, business owners need to know what type of services you need so looking at their portfolios will help you identify if they offer necessary services for your business.

It's also helpful if they have clients under portfolios that are similar or within the same industry as your business. This gives you a feel for how experienced they are in your industry and if they have success with your target audience.

Communication Style

Compatibility is big when it comes to working with a service provider. When assessing prospective firms, it is important to know or see if their culture, communication style, and support structure suit your business.

Imagine the headache of coordinating with a team that does not complement your communication approach or company culture. Matching with a team that suits your style will ensure effectiveness, avoiding misunderstandings and aligning both parties on the project goals.

Geographic Location

SEO projects inherently require location knowledge whether it's international or global. Depending on the nature of your project and business, you should consider the geographic location of the SEO firm.

For example, if you’re targeting local consumers, consider hiring a local SEO team that has experience navigating your market. Their deep understanding of local consumers, market trends, and competition can give you more value. On the other hand, if your business is expanding to more markets, working with a remote SEO team or outsourcing a service provider from that location can be beneficial. It ultimately depends on your needs and goals.

Moreover, you should be mindful when hiring a team from a different country or region because time-zone differences might impact collaboration. If you choose a service provider abroad, see if they have a good track record working with clients in your time zone to ensure that they can accommodate your schedules.

Budget

Financial viability is one of the biggest concerns of running a project with service providers, especially considering that SEO isn't usually a one-off project. As you search for a service provider it's important to match with a partner that fits within your budget to avoid spending beyond your business’ financial capacity.

When you discuss your project with them they should be able to provide a clear cost breakdown to help you effectively allocate your resources and avoid unexpected expenses.

Moreover, sometimes the cheapest option isn't the best option when it comes to partnering with service providers. Since there are plenty of options, take your time finding the firm that brings the best value for your investment. That means the cause of their services should match the quality of their work and their support services.

Look For A SEO Firm With The Right Expertise

SEO is a pretty diverse service and every project requires different expertise, skill sets, and technical knowledge to successfully pull off. Here at the focus areas in SEO that you should weigh up:

• International SEO: The process of optimizing your website’s performance on a global or international scale, focusing on different languages and countries to drive organic traffic from your target locations. Just like geotargeting, international SEO is for businesses that are looking to expand their reach or penetrate foreign markets.
• Local SEO: Contrary to international SEO, local SEO is centered around attracting local consumers, helping any business that has a physical location in a specific area make themselves visible to prospective customers there. Local SEO is arguably one of the most important digital marketing strategies for small businesses or brick-and-mortar stores looking to drive foot traffic and sales.
• Link Building: A popular and effective SEO tactic that involves getting other websites to link to your website to boost its authority and help rank higher on search results. Consistent link building is important to establishing a trustworthy perception for your business, propping its relevance to browsers.
• Multilingual SEO: It’s often misconstrued as international SEO but multilingual SEO focuses on localizing your website’s content into another language. It prioritizes languages rather than location.
• On-Page SEO: The process of optimizing websites and web pages for both users and search engines. It aims to help the site rank higher on relevant search queries and drive strong organic traffic.
• SEO Content Creation: The key to a strong SEO strategy is content creation combines technical SEO strategies with creativity. It requires thorough keyword research, keyword optimization, and content organization.
• SEO Mobile Optimization: Also known as mobile SEO, it’s the practice of optimizing your website, strategy, and content to rank better on mobile search engine results pages (SERPs). It focuses on providing a better experience for smartphone and tablet users.
• Technical SEO: As its name suggests, technical SEO focuses on the technical requirements of search engines such as crawling, rendering, and website architecture.
• Website Migration: Basically, website migration is the process of transferring a website to another online location. In SEO, it means ensuring that the website retains its search engine ranking and domain authority so it doesn’t lose its online visibility.

5 Questions to Ask SEO Firms

Asking about their approach will give you insights into their process and how they personalize their solution to fit your website’s needs. By asking this, you’ll see if they truly understand your project, needs, and goals. Listen carefully to their answers and see if they already have a proven structure for analyzing and personalizing their SEO strategies.

Effective SEO teams don’t just execute, they should have a regular, transparent, and structured reporting process to ensure that all efforts remain aligned with the project’s overall goals. They should give you examples of how detailed their reports are, how frequent they will report to you, and what key metrics they closely monitor.

Adding a question about the tools they use gives you a glimpse into their processes and helps you see if they’re maximizing the latest and best tools. This question gives you a feel of how in tune they are with the latest trends as different innovations have become integral to the entire SEO process.

Project timelines are always a big talking point for outsourced projects. Asking when you can expect to see results doesn’t necessarily mean that you’re rushing them, it’s a great way for you to gauge whether they can provide a realistic timeline for you. SEO doesn’t deliver instant results, but it’s important to know their expected time frame to effectively track their progress.

Additionally, if they promise you concrete results in just a few weeks, don’t take that as a good sign. Ask them further questions as to how they can make that possible. Be wary because SEO typically requires six or more months to see substantial results.

If you think that mobile SEO won’t be helpful to your business, then think again because it’s one of the most important foundations in modern SEO. By asking about the approach to mobile SEO, you gain insights into how cohesive they can tie your web and mobile SEO efforts together.
