Choosing The Best SEO Company for Your Search Marketing Campaign

Choosing an SEO company for your project can seem like a tough task. Each company seems to have different pricing and different types of SEO packages. If you’re a marketing director, you know it’s quite easy to get lost in a sea of competing digital marketing agencies and SEO firms, with more popping up every day as the SEO industry continues to flourish and attract more professionals. Below are some tips on choosing an SEO agency.

Here’s what to look for from an SEO company

  • SEO experience within your industry

    An SEO company with experience in your industry can be beneficial as they can leverage past successes, but is not always necessary. Remember, no matter what products or services you sell, the Google algorithm is still the same. With that being said, if you’re an eCommerce business be sure to select an SEO agency focused on eCommerce SEO. The same goes with lead generation – if generating leads is your primary goal be sure the agency is experienced in increasing leads through organic search.

  • Proven SEO strategies and results

    A reputable SEO company should utilize SEO strategies they’ve proven to move the needle. The best SEO strategies are built based on proven methods, meaning those strategies are currently working for other clients with websites and businesses similar to yours. If you ask, they should have no problem providing case studies, examples, and testimonials of businesses like yours.

  • Ability to provide related digital marketing services

    At OuterBox we offer website design, development, PPC management, and other digital marketing services under one roof. It can be quite beneficial to have one company handle all of these services, not only from a communication perspective, but you should see better results across all marketing channels. SEO and paid search work hand-in-hand, making its extremely important these marketing efforts are coordinated.

  • They rank for competitive SEO keywords

    The best SEO companies know how to do SEO for their website. Ask the SEO company you are considering hiring to tell you about their SEO efforts on their company website. You can also look up any agency’s SEO statistics using tools such as Ahrefs, Spyfu, or SEMrush. You’ll want to see which keywords they rank for, how competitive those keywords are, and how much traffic SEO brings to their website. The SEO company you choose should hold top positions on Google for competitive SEO industry keywords.

  • SEO is their primary service

    Be sure to work with a true SEO firm and not an agency that offers SEO services on top of their other main offerings. If they are a social media marketing company or PR firm, it’s better to not engage in an SEO campaign with them. Leave SEO to the true SEO professionals.

SEO Company Results

What Does a Successful SEO Campaign Look Like?

Many SEO companies will try to paint a pretty picture that simply doesn’t exist while you wait for tangible results. If your SEO company is constantly giving you excuses, remember that SEO is about your ROI. Your SEO strategy should be clear and you should understand where the agency is taking you.

What should you see from a successful SEO campaign?

  • Increased Keyword Rankings

    The easiest way to measure the success of your SEO campaign is to look at the positions of your most important keywords. You should have a baseline report of your keyword positions before the campaign started to look back at. Are your keywords now higher in the SERPs (search engine results pages)?  If you’re moving up, your SEO campaign is on the right track.

  • Increased Organic Traffic

    Does Google analytics show a significant increase in organic traffic as a result of those keyword ranking improvements? Be sure to check your most important pages. These pages are typically the landing pages that drive the most leads, revenue, or whatever you’re considering a conversion. To see your organic traffic in Google Analytics navigate to “Acquisition” > “Campaigns” > “Organic Keywords”.

  • Increased Organic Conversions

    Is the increase in organic traffic qualified? If so, you better see a significant increase in organic conversions! If your SEO company is only driving unqualified traffic to blogs, articles, etc., the campaign will not be a success even though your website has more organic traffic.

  • Increased Sales & Revenue from SEO

    If your site is eCommerce, your ultimate ROI can be broken down to organic revenue. If your total organic revenue isn’t improving at a rate that can justify your monthly SEO spend, it’s likely time to reconsider the agency you’re working with.

SEO Companies FAQs

What is an SEO company & what do SEO companies do?

An SEO company provides search engine optimization (SEO) services. The goal of an SEO company is to increase the visibility of a website in organic search engine results to increase the amount of organic traffic to the website. There are a plethora of services rendered by the SEO company to help achieve this goal.

These SEO services include:

  • Keyword research
  • On-page optimization
  • Off-page optimization / link building
  • Content planning
  • Content writing
  • Optimization of current content
  • Technical optimization / code optimization
  • Landing page creation
  • Internal link building
  • Conversion rate optimization
  • Video optimization
  • and much more

While the services an SEO company provides are important, in the end, it’s important to evaluate the impact of the company’s SEO efforts on your bottom line sales.

Is hiring an SEO company worth it?

If you’re asking this question, you are likely too early in the research process to understand the value of SEO services. However, that doesn’t mean you shouldn’t hire an SEO company. If your website stands to benefit (financially or otherwise) from improved keyword rankings and increased traffic from organic search engines like Google, hiring the right SEO company can be a game-changing decision.

The first step you must take to determine whether or not you should hire an SEO company is to figure out if your website would benefit from SEO services. Once you make that determination, you need to figure out if it makes sense to hire an outside agency or attempt to perform these services in-house. Whether or not SEO agencies are “worth it” or not depends on a tremendous variety of factors. Contact us today to schedule a free SEO visibility audit and discuss your needs in person or over the phone.

How do I choose an SEO company?

Choosing an SEO company is no easy task. We’ve put together this list of the top SEO companies in an attempt to make it easier to find reputable and reliable SEO agencies. When deciding on an SEO company, you should look for a company that has experience working within your industry and can provide examples of tangible results. Be sure you feel comfortable with their team, the people you’re talking to, and their responsiveness to your requests. Remember, if all goes well, you’ll be working together for years to come!

How do I find the best SEO company?

The truth is, there isn’t one “best SEO company”. You need to find the best SEO company for your business. Look for a company that specializes in optimizing websites with goals (b2b, lead generation, eCommerce, etc.) that are similar to your website. For example, OuterBox consistently ranks as a top eCommerce SEO provider, so if you sell products in an online store, we are an ideal SEO services partner for your business.

You’ll also want to look for a company that can provide examples of tangible results, case studies, and testimonials from satisfied clients. If the SEO company you are considering cannot provide these, you should look elsewhere.

Why is SEO important?

Ranking at the top of Google and other major search engines when the keywords most associated with your products and services are searched creates a huge boost in leads and online sales. With billions of searches each day, internet users start at Google when looking for anything to buy. If you don’t rank organically you may be reliant on paid search or other advertising methods that can get very expensive. Rankings organically is one of the highest ROI providing forms of advertising available.

What are the most common SEO services that agencies provide?

The best SEO agencies provide a wide range of services to help businesses improve their online visibility and increase traffic to their website. Some of the services they provide include:

  • Keyword research: Identifying the most relevant and popular keywords that people use to search for products and services related to a business is key to any SEO campaign. These keywords are then used in content, title tags, ALT tags and other areas of a website to help it rank higher in Google and other search engines.
  • Competitor research: Understanding your competitors and their strategies are key in creating an SEO strategy. An SEO agency should look through your competitors content, site structure and backlink profile to determine how your strategy can place your website above theirs.
  • SEO Audit: Creating a detailed SEO audit is an important part of the SEO process and one an SEO company shouldn’t skip. Sometime audits will be a paid service or will often be delivered during the proposal process.
  • On-page optimization: On-page SEO involves optimizing the content and structure of a website to make it more search engine friendly. This includes optimizing titles, meta tags, headings, and alt tags.
  • Off-page optimization: This services include building high-quality links from other websites back to a business’s website as it helps to improve the authority and credibility of a website, which can lead to higher search engine rankings.
  • Local SEO: Optimizing a business’s website and online presence for local search results is important, especially for local businesses. The process of optimizing business listings on local directories, such as Google My Business, and building local citations is a key to ranking in map results and other local search results.
  • Content marketing: To rank for competitive keywords creating and promoting high-quality content that is valuable to a business’s target audience is a must. This can include blog posts, articles, infographics, and other types of content that are relevant to a business’s products and services. Content marketing is a critical part of any SEO campaign.
  • Technical SEO: This involves optimizing the technical aspects of a website, such as the website’s speed, mobile-friendliness, and security, to help it rank higher in search engine results. It can also include adding or optimizing schema and other tags on your website that help Google understand what the page is all about.
  • Detailed Monthly Reporting: Understanding what your SEO agency is doing and the results you’re getting from SEO is very important. Any top agency you choose should deliver detailed reporting.
