Link Building Service #2: Digital Olympus

The second link building service on our list is Digital Olympus.

Again, like we did with the previous link building service we presented, we’re going to do an overview of what Digital Olympus is, what the price range of the agency is, as well as have a look at their case studies.

Without further ado, let’s get right into it.

What is Digital Olympus?

Digital Olympus is yet another link building services agency that focuses on building quality links for their clients.

To use their very own words;

“We’re a link building agency that gets you links you can be proud to have.”

This link building company is specifically helping their clients acquire high authority links.

Let’s now have a closer look at pricing and then analyze their link building approach.

Pricing

The Digital Olympus pricing model is based on the Domain Authority (DR) of the referring domain’s website.

In other words, the price per link depends on how authoritative the referring website – that is, the website where the link is placed to – is.

The more difficult it is to receive a link, based on the Ahrefs DR, the more expensive the link will be.

Online reviews

Digital Olympus’s client reviews are all phenomenal and highlight the team’s professionalism and hard work.

What’s visible from the client testimonials one finds online is that the agency, and more specifically its founder, Alexandra Tachalova — who’s well-known in the digital marketing field — is heavily focused on its relationship-focused approach when it comes to link building.  

That, alongside their high-quality service, seems to be making a huge difference in terms of how their clients feel about the agency and the work they deliver.

Clutch reviews: N/A

Approach to link building

The Digital Olympus team follows their own rules when it comes to link building.

They’re not focusing on spammy email outreach or low-quality links, but on building links manually and performing relationship-based link building.

Doing manual outreach and building links only through white-hat tactics is one of the strong points and main differentiators between Digital Olympus and other link building agencies.

We could say that Digital Olympus works towards creating personalized and tailor made link building strategies that work individually and more efficiently for each company depending on their needs.

Here are some keys points of the process they follow:

• Link prospecting
• Client’s approval and participation in the process of finding links and websites
• Monthly link building report
• Tracking link status – to make sure links remain dofollow and aren’t turned into nofollow
• Fast link delivery through the company’s well established connections with a number of sites across different industries.

To be more specific, these are the five main steps they follow in terms of their link building strategy:

Case studies and overall reputation

After having seen some of the agency’s clients and approach in terms of link building strategies they’re following to help get the results they want, we’re looking at a few case studies.

These prove the agency’s efficiency in acquiring links based on relevancy and quality.

More specifically, we couldn’t skip over mentioning one of the company’s greatest success stories.

It comes as a result of the collaboration between Digital Olympus and EdX.

What the team did in this case was they managed to build over thirty links to a specific category page on the client’s website.

This resulted in an incredible boost in terms of the website’s organic traffic.

To be more precise, the link building strategy doubled the page’s organic traffic from ten to twenty thousands visitors per month.

The Alternative to Link Building Services

We’ve presented you with eight link building services that we think can help you get the job done.

However, we couldn’t miss mentioning that there’s an equally efficient way to deal with link building.

That is, to run your link building campaign on your own.

Respona is an efficient link building software that could totally be your ally in terms of running your own campaign.

Our process for helping you build high-quality backlinks is explained in the most simple way here:

First of all, you can use Respona to identify outreach opportunities.

Running your campaign through Respona can be beneficial for you in terms of making sure you’re following the right steps to make a killer link building campaign.

Still not convinced?

We hope that the following chart will help you understand the difference between doing link building by yourself in comparison to hiring a link building service.

This isn’t to say that there’s no value in building links through a link building service like the ones we’ve shown you in this guide.

In fact, hiring such a service can be really beneficial for your business.

However, at the same time, we can’t over-emphasize the benefits of building and launching your own link building campaigns.

Let’s wrap this up and close with some final thoughts.

Wrapping Up

The purpose of this guide is to help you choose a reliable link building service.

Having said that, now that you know some of the best link building services out there, you should go on to evaluate them for yourself.

Ask questions, request case studies, read online reviews, and try to find the best service for your business.

On the other hand, knowing that there’s an alternative to link building services such as the ones we presented, you can choose to do link building by yourself.

Both options can be effective.

Evaluate the pros and cons of each and make a decision that will help you grow your business.

Good luck!
