B2B SEO vs B2C SEO - What’s the Difference?

There are some major differences between B2B and B2C SEO, which includes:

• B2B SEO targets decision-makers who represent their organization’s interests, while B2C can target literally anyone.
• B2B keywords tend to have lower searches, as less people look for business-related topics than lifestyled-related ones.
• B2B traffic can have a significantly higher ROI.
• SEO can be very, very hard in B2B competitive industries (e.g. email marketing SaaS).

What Can a B2B SEO Agency Help With?

A B2B SEO agency can help you with every step of the SEO process, including:

• Keyword research - Identifying keywords relevant to your business and prioritizing them by difficulty and likelihood to convert.
• Content audit - Analyzing all content published on your website and ensuring that it’s optimized for a keyword, and follows SEO best practices.
• Content creation - Coming up with content ideas, ensuring that articles fit search intent, and creating high-quality, long-form content.
• Link-building - Acquiring backlinks for your website through guest posting, outreach, and broken link-building (among other tactics).
• SEO management - Keeping constant track of your rankings and ensuring that your search traffic is growing over time. Making adjustments to articles, headlines, and pages in case something doesn't rank.

How to Hire The Right B2B SEO Agency

When choosing a B2B SEO agency, evaluate the following criteria.

#1. How Does the Agency Run Their Own SEO?

Check how the B2B SEO agency you’re interested in is doing in terms of their own SEO. Some things you can look out for include:

• Content quality. Do they create high-quality SEO content for their blog? Or is it just short-form, 500-word generic articles?
• On-page SEO. Do they follow SEO best practices? E.g. meta descriptions on images, keyword-specific URL slug, etc.
• Rankings. Do any of their pages rank on Google? For example, at Apollo Digital, we rank for some competitive keywords like “SEO case study” and “digital marketing case studies.”

#2. What Are Their Results in B2B SEO?

Make sure that the B2B SEO agency has a track record of success.

After all, you don’t want to be working with someone that only talks big.

Check for the following:

• What results have they achieved for their clients? Over what timeframe?
• Do they have published case studies? Are the case studies well-written? Does the client still rank well?
• Have they worked in the B2B industry before? Do they have experience in your specific field?

#3. Is Their Proposal Strong?

A lot of B2B SEO agencies have a very generic, copy-paste proposal template they submit for every lead.

If you receive something like that, it means that the agency didn’t even look into your case all that much. So, whatever results they may be promising may be full of hot air.

Instead, you want to receive a proposal that outlines the following:

• The current situation with your website. What are your current SEO strengths? Weaknesses?
• What’s their action plan (with a timeline)? What are they going to do for you in the first month, and every month after that?
• Are their results forecast realistic? E.g. if they promise to get you results in 6 months, and your website is completely fresh, chances are, they either don’t know what they’re talking about.

#4. Do They Understand Your Business?

The agency should have a good understanding of what your business is and how it works.

This will allow them to prioritize keywords that are more likely to convert and lead to sales.

A good indicator here is if the agency is asking you a lot of questions about your business, product, or service.

B2B SEO FAQ

Have some more questions on B2B SEO, or working with a B2B SEO agency?

We’ll answer them here!

#1. What’s B2B SEO?

B2B SEO is an online marketing strategy that helps you rank for search terms related to your B2B business.

If you manage to succeed with B2B SEO, you’ll be able to drive hundreds or even thousands of qualified leads to your website every month, all without spending 5-figures on ads.

#2. Is B2B SEO dead (or dying)?

Nope - SEO is not dead, and it’s not going to die anytime soon. There’s no real argument for “SEO being dead” other than some media websites wanting to drive clicks by writing about something controversial.

Blackhat SEO, though, is definitely dead. In 2021, you just can’t “hack” Google - you need to play by the rules and get results organically.

#3. How much does B2B SEO cost?

It depends if you’re looking for local or global B2B SEO.

If, for example, you’re a local B2B accounting firm, you’d be looking at a spend of $1,000 to $5,000 per month to work with a qualified B2B SEO agency (depending on the competition in your location).

On the other hand, if you’re a B2B SaaS (e.g. accounting software), you’d need to utilize global SEO, which is a lot more competitive (and accordingly, expensive). To get some serious results, you’d need to spend anything from $5,000 to $15,000 per month (again, depending on competition and SEO vendor).

#4. How long does B2B SEO take?

Depending on how competitive your niche is, you’d need anything from 6 months to 3+ years to see results with SEO.

Yep, it’s a wide range, but it really depends on a lot of factors.

For example, if your website is aged and has a TON of backlinks, you’d be able to get results in a competitive field in 6 months to a year.

On the other hand, if your website is completely fresh, it might take 2 to 3 years.

#5. Should I hire a B2B SEO consultant or an agency?

If you’re looking for full-service SEO management, you’re better off with an agency. They’ll help with every step of the SEO process, from strategy to content creation.

If, on the other hand, you already have a strong marketing team, you can hire an SEO consultant, who’ll help drive strategy while you’re in charge of execution.
