And last but not least, as we reach the end of our recap into the wonderful world of online advertising tools to make 2021 sparkle and shine, let’s take a look at the core building block of any solid campaign. That of course, being…

SEO Tools

Any campaign that’s worth its weight in digital gold has to, and I mean HAS TO, be acknowledged by Google (and a few other key search engines). If your campaign is not ranking, it will not be seen and likewise, if your campaign is not seen, it’s certainly not ranking (a little virtual paradox to keep in mind). So, how do you rank? Well, the good news is that SEO tools these days are so advanced, they tend to do most of the legwork for you. Here are two of them.


If you haven’t heard of these guys, you have now. SEMrush is one of the top SEO tools on the market today and the undisputed don of all things digital. It is a tool that works around the clock to improve your site’s online visibility, discovering marketing insights along the way and providing you with an almost endless list of tools and reports to help you step up your SEO, in line with keyword research, campaign management, marketing insights, and campaign rankings. 

Some of the features in the SEMRush platform include…

Position Tracking Tool
Improve your search rankings straight out the gate with this nifty tool. Track your site/campaigns position for a host of different keywords and group them according to various high impact tags. 

Competitor Research
This tool gives you a window into what your competitors are doing in terms of their own SEO. It shows you where they are currently ranking on Google and for what. This gives you a unique opportunity to pinpoint and target similar (or identical) keywords, which in turn gives you the potential to rank higher and attract more users to your content. 

Keyword Magic Tool
One of the most comprehensive keyword research tools in online advertising. This tool allows you to pinpoint new and exciting keyword opportunities to use in your latest or upcoming campaign. This tool has a built-in competition score, so you can identify keywords that are a little more niche and would ultimately rank better.

Surfer SEO

A go-to platform for all things SEO, specifically known for its ability to assist in fully optimizing written content. The Surfer SEO tool automatically analyzes your site or campaign content by sifting through 500+ on-page signals. From there, it provides you with the metrics to rank higher and optimize for better keyword placement. The platform also has a fully integrated keyword research tool with the ability to analyze and recommend page 1 SERPs for the specific words you are targeting. 

A few of the features that make your SEO optimization a whole lot easier include…

The SERP Analyser
The platform’s signature tool and a game-changer in “Do it Yourself” SEO for the masses. The SERP Analyzer feature breaks down your  SERPs (Search Engine Results Pages) and refines them according to the keywords that carry the most in page traction. The SERP feature gives you access to a host of different insights, including. 

  • The average word count.
  • The keywords frequency on a given page.
  • The page speed.
  • The character count in title tags.
  • The potential of the given Alt text.

Sentiment Analysis
So, this is an interesting one and a must-have when running campaigns in different regions. The Sentiment Analysis feature identifies natural language and implements it across all content. It uses cutting-edge algorithms to predict and replicate different regional figures of speech, dialect restriction, and the like. Now you can see if the content you’re putting out is construed as positive, negative, or neutral. Granted, this doesn’t help much in the way of hardcoded SEO gains, but it can go a long wait to knowing whether your speaking to the right region and how the audience is reading your messaging, especially if you have limited characters or space to play with.

And then you’ve got the…

Content Editor Tool
In a nutshell, this awesome feature allows you to outline and write content that’s entirely optimized for a host of different search engines. Once you’ve written your content, a built-in crawler will scan the content for LSI keywords, and where applicable suggest them. LSI’s are basically signified, that alert search engines that the copy is genuine, original, and that it’s been written with a keen knowledge of the given subject. All very good indicators for Google. It’s as simple as that really. The tool will give you the exact keywords you need as well as analyzing page 1-5 search results for further insights. All that’s left then is for you to add them in and presto! You’re an SEO whizz before you even know it.

Phew! That’s it for now. With so many online advertising tools on the market today, we’ll refine this list as we go. What’s important now is that you hit the ground running in your 2021 online advertising journey and rake in bigger and better ROI’s as you go. 

Let us know how it’s going? We’re keen to hear it, and as always, you can reach out to us any time of the day or night for questions, queries, and heck, just to say hi! 

Wishing you the best for 2021 and a profitable road ahead.
