20i SEO tools

Learn SEO: The SEO tools, blogs & podcasts we love at 20i

SEO is an extremely broad topic. From content & keywords, down to the most in-depth technical audits, there is a wide variety of areas to cover if you want to learn SEO. 

With so many tools and learning resources to choose from, finding the right ones for you can be a bit of a minefield. 

We work hard on SEO ourselves here at 20i – we’ve used a wide array of tools and watched hours of webinars – and we have our favourites. 

So, to help you out if you’re looking for some inspiration, here are the SEO tools and resources we utilise here on 20iLet us know your favourite SEO tools or blogs in the comments below. 


I’m personally a huge fan of Ahrefs and it is the go-to SEO software for a lot of our research and performance monitoring. 

It isn’t cheap, and I wouldn’t use it for non-revenue generating websites, but it is packed with powerful features and useful tools. 

I much prefer the UI and UX of ahrefs to the likes of SEMRush and Moz, which I’ve both used and have never felt as comfortable interacting with the data. 

The reports we use a lot include: 

Keyword research 

Ahrefs keyword research tool is one of the most advanced out there, with loads of options to expand the data or drilldown further. 

As you can see below, web hosting is incredibly competitive with a very high difficulty score (Keyword Difficulty gives an estimate of how hard it is to rank in the top 10 organic search results for a keyword on a 100-point scale). 

Also, ‘web hosting uk’ is a more popular search term than ‘uk web hosting’: 

Site Audit 

Ahrefs will crawl all the pages on your website and flag any SEO issues it finds, as well as recommendations on how to fix them.

The reports cover issues related to: 

  • Performance: slow pages, too-large CSS or HTML 
  • HTML tags: missing, duplicate or non-optimal length of title tags, meta descriptions and H1 tags 
  • Social tags: incomplete or missing Open Graph tags and Twitter cards 
  • Content quality: low word counts, unconsolidated duplicate pages 
  • Localization: all issues with Hreflang 
  • Incoming links: detecting orphan pages, issues with nofollow links 
  • Outgoing links: detecting links to redirects, broken pages 
  • Resources: issues with images, JavaScript, CSS 

We’ve set up a daily report to make sure any issues that may crop up are identified and fixed asap. 


How many new links have we gained in the past x days? 

A lot of these links come naturally, but we do occasionally conduct a bit of outreach, especially when we publish something meaty like the web designer survey

This report let’s us know how successful that has been. 

Although proprietary and totally unconnected to Google’s ranking algorithm, the ‘Domain Rating’ metric is useful to gauge how much ‘authority’ a linking domain has, the higher the better. 

This report isn’t limited to your own site. It can also be used to track competitors’ links and identify opportunities for your brand. 

Best pages by incoming links 

This report is great for identifying your top pages by external links (do more content like that) as well as other sites’ links. 

With this information you can apply a few well-trodden tactics to acquire some of those links yourself (skyscraper technique anyone?). 


Although ahrefs is an important part of our SEO tool set, it isn’t perfect. 

The biggest downer is the frequency of updates for your tracked keywords’ SERP rankings. 

At best you’ll get updates every 3 days on the agency plan, which is a whopping $999 per month. 

To plug that gap, we use SERanking for daily updates. 


We use SERanking to monitor how our target keywords are performing in Google’s SERPs daily. Are there any unwelcome drops we need to investigate or are there are increases thanks to changes we’ve made? 

Getting set up is easy, and the interface is clean and easy to use.

It also comes with website audit, backlink checker and social media management tools, but we don’t use those. 

Other keyword research tools 

It’s always good to get second opinion, so sometimes we make use of SEMrush, AnswerThePublic, and AlsoAsked. These all present results in different ways – for example, some of these concentrate on questions – but they can help to widen your scope. 

Schema markup tools 

We have developed our own Schema generator which can be used for free by anyone and it’s the only one that includes entity and website hierarchy markup. 

With just a few clicks and inputs it will spit out valid schema markup for you to add to your site. 


Like the above, SEO Review Tools includes lots of free online tools. It’s useful for ‘filling in the gaps’ in our toolset. For example, they offer a useful keyword density checker to make sure that we’re not over-optimising to the point of getting spammy! 

Google’s tools 

Google Search Console (GSC) provides us with insight in to how successfully Google is crawling our content along with how we are performing against the market (search impressions and clicks). 

We tend to use GSC to identify the areas where we could improve, such as Core Web Vitals, schema and mobile usability. 

We use Lighthouse to test page speed – more information about that tool here. 

For diagnosing Cumulative Layout Shift, we use web.dev’s CLS debugger. This is really useful for our developers to narrow-down the source of a poor CLS score. 

Screaming Frog 

This site crawler – or ‘SEO spider‘ – offers great bulk metrics about our website, for example, if we want to know PageSpeed Insights scores of all our pages. 

It’s most well known for being able to find broken links on sites. This is useful for looking for link opportunities. It has a bunch of other features – too many to list here! It’s available in both free and paid versions. 

20i Website Acceleration Suite 

Pagespeed is a key part of SEO, and a large part of this is underpinned by the size of your web pages and avoiding bloat. 

As such, we created our very own 20i Website Acceleration Suite – a tool which is included for free in all of our hosting 

The website acceleration suite improves website load times by automatically implementing web performance best practices to a website. This includes optimising images, JavaScript minification and combining CSS – all to improve website load times and the Google PageSpeed Score. This in turn positively impacts SEO and helps you develop high-performing websites at scale. 

SEO Pro 

SEO Pro is a simple Chrome extension, which can be used to quickly and easily to check the basics of a page, such as headings, alt-text and schema. 

SEO blogs we read 

Because we’re huge marketing nerds (and because it is our job) we regularly check in with top SEO blogs/news sites to get the latest news and ideas. 

There are countless SEO blogs out there, so here are the ones we’d recommend checking out: 

  • Backlinko: Not as frequently updated as it used to be but there’s loads of really good content to go through 
  • Google Search Central Blog: Get the news straight from the horse’s mouth as well as future developments 
  • Marie Haynes: Specifically if your site is heavily impacted by EAT or in a YMYL sector 

SEO Blogs 

Newsletters and the other sources above are a good way to keep up to date with the recent chatter in the SEO community. But for diving deeper into the nitty-gritty of a topic, blogs offer often a more detailed view and analysis. 

First is the blog from Olaf Kopp – https://www.kopp-online-marketing.com/blog. Olaf is well known in the German SEO scene and recently started publishing his content in English – it’s really worth reading.

SEO Newsletter that are worth reading: 

Aleyda Solis: #SEOFOMO 

Aleyda Solis has won several awards over the past years and has established herself as one of the most respected experts in the world of SEO. Her weekly newsletter #SEOFOMO is one of the few that doesn’t pitch her own service and delivers useful insights and tools: 

Google Developers Newsletter 

If you want to know what is happening at Google, what better place to look at their own newsletter? Stay up to date with changes and development and get all the Info directly from the big guys. 


Search Engine Land 

If you need the daily buzz (and can handle it) of what is happening in Search – Search Engine Land serves you with a daily roundup of the news and stories around SEO and Digital Marketing. A lot (I mean really a lot) of information, provided by some of the big names in our industry. 


These are great sources of information to stay on top of what’s going on in the always evolving SEO universe. 

If you’d pefer a more light hearted, easily digestible way to keep your finger on the pulse, then SEO YouTube channels and podcasts may be for you. 

Best SEO YouTubers and Podcasts 

As SEO’s, we like our written content, but there are also tons of vlogs, channels, and podcasts available to keep you informed too. 

Google Search Central on YouTube 

Straight from the horse’s mouth. You can watch the Google SEO Office Hours and Google Search News with John Mueller and find lots of other valuable info on this channel. Google can often be slightly reserved with how much information they’re willing to share with people, but if it comes from any of these sources then you know it’s official. 


302 of a kind 

Every Friday at 4pm (CET) before we 302 off on the weekend, Marcus Tandler and Izzi Smith round up the week. An entertaining hour with jokes and beers but nevertheless some serious reviews of what is going on in and around the world of SEO. It’s broadcasted live on YouTube, LinkedIn and Facebook. 

302 of a kind – YouTube 

Authority Hacker Podcast 

SEO nerds chat with peers. The really nice thing about this podcast is, that it features examples and case studies showcasing a lot of practical tips.

What it says on the tin. Podcast with Jason Barnard (aka The brand SERP guy). Discussion with guests (mostly well known in the industry) on SEO and wider digital marketing topics.

Rankable Podcast – iPullRank 

20i SEO guides 

We’ve also produced some great, in-depth guides to help you improve your SEO: 

No one knows it all! 

There’s a whole goldmine of information to be found within these sources, but it’s important to remember that nobody knows it all. No matter how good you are, I don’t think anybody can cover all the vast variety of topics that are needed to be successful by themself. SEO is such a broad, rapidly changing, and sometimes vague topic, that sometimes there isn’t always an answer to your question! 

Over to you 

Are there SEO-related tools/blogs that you use that you’d recommend? Any that you wouldn’t? Do you prefer to dive into keyword research, or is fixing technical errors your bag? Let us know in the comments below. 


  • Nicely put together.
    We use both Ahref and SEMrush in tandem. Ahrefs for Backlinks and Keyword Research and SEMrush for everything else. But I certainly can relate to these burning a hole through your pockets.

    • The cost can soon mount up. Why do you prefer using ahref’s backlink and keyword data?
