At its heart SEO (Search Engine Optimization) developed as an extension to web accessibility by following HTML 4 guidelines, in order to better identify the purpose and content of a document.
This meant ensuring that web pages had unique page titles that properly reflected their content, as well as keyword headings to be better highlight the content of individual pages, and that other tags were treated the same accordingly.
This was necessary, not least because web developers were often only focused on whether their coding worked, rather than the user experience, let alone following web publishing guidelines.
This slowly changed as it became increasingly known that search engines used these "on-page" signals to provide their "Search Engine Results Pages" (SERPs) - and that there was an advantage to ranking higher on these to tap into free and natural organic traffic.
The internet has evolved a lot since those early days, and major search engines such as Google now process far more "off page" information when determining their search results, not least by using semantic processing, collating user data, and applying neural networks for the machine learning of patterns, trends, and personal preferences.
Even still, the core ideals of SEO remain the same as they always have - that of ensuring pages have the correct tags for targeting keywords, not just for natural search results, but also for PPC (Pay Per Click) and other marketing campaigns, where call-to-action (CTA) and conversion rates are essential indicators of success.
But how does a business know which keywords to target on its sales pages? How does a website filter transactional traffic from general site visitors? And how can that business increase its ability to capture targeted traffic from across the internet? Here we list a number of tools that will help do exactly that.
Best SEO tools - at a glance
1. Google Search Console
Who better than the search giant Google to improve your SEO?
Google Search Console (GSC) is an excellent way for newbie webmasters to get started with SEO.
Even if you're not headstrong on SEO, whatever the size of your site or blog, Google's laudable Search Console (formerly Webmaster Central) and the myriad user-friendly tools under its bonnet should be your first port of call.
The suite of tools gives you valuable information about your site at a glance: it can assess your site's performance and observe potential problems to troubleshoot (like negative spammy links), help you ensure your site is Google-friendly and monitor Google's indexing of your site.
You can even report spam and request reconsideration if your site has incurred a penalty. Plus, if you don't refer to their Webmaster Guidelines now and again, well, you've only yourself to blame if you go wrong. Search Console is constantly updated, and new features are on the way, such as new URL inspection tool or the new sitemaps report.
Help is available via the Webmasters Help Community, a place for webmaster's to connect and share troubleshooting and performance tips.
2. SEMrush SEO toolkit
Advanced SEO tools, all accessible from a masterful dashboard
SEMrush SEO toolkit was originally developed in 2008 by SEMrush. In 2018, the project received funding of $40 million for expansion.
The keyword research tool is accessible from SEMrush's super elaborate dashboard. You can view detailed keyword analysis reports as well as a summary of any domains you manage.
More crucially, the SEO toolkit allows you to compare the performance of your pages to see how you rank against the competition. For instance, you can analyze backlinks from other websites to yours. (this process is sometimes as 'link building').
Traffic analytics helps to identify your competitors' principle sources of web traffics, such as the top referring sites. This enables you to drill down to the fine details of how both your and your competitors' sites measure up in terms of average session duration and bounce rates. Additionally, "Traffic Sources Comparison" gives you an overview of digital marketing channels for a bunch of rivals at once. For those new to SEO slang 'bounce rates' are the percentage of visitors who visit a website then leave without accessing any other pages on the same site.
The domain overview does much more than provide a summation of your competitors' SEO strategies. You can also detect specific keywords they've targeted as well as access the relative performance of your domains on both desktop and mobile devices.
SEMrush has received many positive mentions online but has been critiqued for use of SEO jargon such as 'SERP' which may alienate inexperienced users. A 'Pro' subscription costs $99.95 per month which includes access to all SEO tools.
3. SEO Spider
SEO Spider is an effective web crawler but the free version is slightly limited
SEO Spider was originally created in 2010 by the euphemistically named "Screaming Frog". This rowdy reptile's clients include major players like Disney, Shazam and Dell.
One of the most attractive feature of SEO Spider is its ability to perform a quick search of URL's, as well as crawl your site to check for broken pages. This saves you the trouble of manually clicking each link to rule out '404 errors'.
The tool also allows you to check for pages with missing title tags, duplicated meta tags, tags of the wrong length, as well as check the number of links placed on each page
There is both a free and paid version of SEO Spider. The free version contains most basic features such as crawling redirects but this is limited to 500 URLs. This makes the 'Lite' version of SEO Spider suitable only for smaller domains. The paid version $180 per year and includes more advanced features as well as free tech support.
4. Majestic SEO Tools
A royal offering for all backlink tinkerers
Majestic SEO tools has consistently received praise from SEO veterans since its inception in 2011. This also makes it one of the oldest SEO tools available today.
The tools main focus is on backlinks, which represent links between one website and another. This has a significant influence on SEO performance and as such, Majestic has a huge amount of backlink data.
Users can search both a 'Fresh Index' which is crawled and updated throughout the day, in addition to an 'Historic Index' which has been praised online for its lightning retrieval speed. One of the most popular features is the 'Majestic Million' which displays a ranking of the top 1 million websites.
The 'Lite' version of Majestic costs $50 per month and incorporates useful features such as a bulk backlink checker, a record of referring domains, IP's and subnets as well as Majestic's integrated 'Site Explorer'. This feature which is designed to give you an overview of your online store has received some negative comments due to looking a little dated. Majestic also has no Google Analytics integration.
5. Moz Pro
Community supported search marketing tools
Moz Pro is a platform of SEO tools that aim to help you increase traffic, rankings, and visibility across search engine results.
Key tools include the ability to audit your own site using the Moz Pro spider, which should highlight potential issues and recommend actionable insights. There's also the ability to track your site rankings over hundreds or even thousands of keywords per website.

Even if you don't sign up to Moz Pro, a number of free tools are available. There's also a huge supporting community ready to offer help, advice, and guidance across the breadth of search marketing issues.
Best free SEO tools
Although we've highlighted the best paid-for SEO tools out there, a number of websites offer more limited tools that are free to use. Here we'll look at the free options.
SEOquake is one of the most popular toolbar extension. It allows you to view multiple search engine parameters on the fly and save and compare them with the results obtained for other projects. Although the icons and numbers that SEOquake yields might be unintelligible to the uninformed user, skilled optimisers will appreciate the wealth of detail this add-on provides.
Gauge details about number of visitors and their country, get a site's traffic history trended on a graph, and more. The toolbar includes buttons for a site's Google index update, backlinks, SEMRush ranking, Facebook likes, Bing index, Alexa ranks, web archive age and a link to the Whois page. There’s also a useful cheat sheet and diagnostics page to have a bird’s view of potential issues (or opportunities) affecting a particular page or site.
Knowing the right keywords to target is all-important when priming your web copy. Google's free keyword tool, part of Adwords, couldn't be easier to use. Plug your website URL into the box, start reviewing the suggested keywords and off you go. Jill Whalen, CEO of HighRankings.com is a fan and offers advice to those new to keyword optimisation: "make sure you use those keywords within the content of your website."
However, while useful for keyword research purposes it's important to realize the numbers provided are approximations rather than exact figures, and intended to provide a guide to popularity rather than exact real-time search volume.
Yet another Google tool on that list (not a surprise isn’t it). Optimise is not for the faint hearted and will make even seasoned SEO experts uncomfortable. SEO isn't all about rankings and without the right balance of content that engages with your visitors and drives conversions, you're earnest optimisation could be wasted.
Google’s free service helps take the guesswork out of the game, allowing you to test your site's content: from simple A/B testing of two different pages to comparing a whole combination of elements on any given page. Personalization features are also available to spice things up a bit. Note that in order to run some of the more complicated multivariate testing, you will need adequate traffic and time to make the results actionable, just as you do with Analytics.
Any seasoned search engine optimisation specialist will tell you keywords matter, and while simply clawing keywords into your text arbitrarily can do more harm than good, it's worth ensuring you have the right balance. Live Keyword Analysis is a breeze to use: simply type in your keywords and then paste in your text and your keyword density analysis will be done on the fly. Don't forget to proof and edit your text accordingly for optimum readability. A must for website copywriters especially as you don’t need to register or pay for anything.
Understanding backlinks (sites linking to you) allows website owners and publishers to see what link opportunities they might be missing out on. Enter Ahrefs, arguably one of the most powerful players out there.
They maintain one of the largest live backlink indexes currently available with over 17 trillion known links, covering 170 million root domains. While Ahrefs isn't free, the backlink checker feature is, which provides a useful snapshot that includes your domain rating, the top 100 backlinks, top 5 anchors and top 5 pages, the strict minimum to provide with a feel of what Ahrefs has to offer.
