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.

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.

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.

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 (return on investment). If you can’t clearly see a positive ROI from the efforts your SEO company is providing, that’s a red flag.

What should you see from a successful SEO campaign?

• Improved keyword rankings – The keywords most relevant to your business should be moving in the right direction. While the major keywords will take the longest, you should start to see positive trends within 2-3 months. Depending on the competitiveness of your industry, time frames will differ, but the positive trends should be there.
• Increased organic traffic – With improved keyword rankings should come improved organic traffic. If your organic traffic is improving, that’s great news. However, be mindful of what pages are attracting the organic traffic. If the traffic is going to blog pages, the organic traffic increase will be misleading because the visitors are going to a blog to read an article that is completely unrelated to the products or services being sold. Organic traffic to key landing pages (product, service, category, etc.) is the type of organic traffic that truly matters.
• Improved conversion rate – What good is organic traffic if it doesn’t convert? A skilled SEO company will help improve the conversion rate of your website by improving on-page elements, user experience, and the overall quality of your website. If the increase in organic traffic is specific to blogs, articles, etc., the campaign will not be a success even though your website has more organic traffic.

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.
