Free digital marketing resources: SEO guides, analytics help, courses and research tools

Which free digital marketing resources are worth your time?

Nine are worth knowing about, and they cover four jobs: learning how search works, setting up measurement, taking structured courses, and doing planning or research. All but two state that they are free. The other two, Google Skillshop and Mailchimp’s resource hub, do not say on their landing pages, so they are marked as unconfirmed.

This page is a short guide, not a ranking. Each entry says what the resource covers, who publishes it and what I could and could not confirm.

Where should you start with SEO?

Start with Google’s own SEO Starter Guide, then add one other explainer. The Starter Guide is published by Google Search Central and explains how Search discovers pages, how to organise a site and its URLs, how to write useful content and how titles and snippets appear in results. It also covers images and video, promoting a site and common SEO misconceptions, and ends by pointing to Search Console (Source: Google Search Central: SEO Starter Guide, accessed Oct 24, 2026). The page shows a last-updated date of 10 December 2025.

If you would rather watch than read, the Ahrefs SEO Course for Beginners has 14 lessons in 5 modules and takes around two hours. It covers SEO basics, keyword research, on-page SEO, link building and technical SEO, and the first lesson can be started without signing up (Source: Ahrefs: SEO Course for Beginners, accessed Oct 24, 2026).

The Semrush SEO Basics Guide is a roughly 20-minute article dated May 2026. It adds search intent, local SEO and how to measure results, including citations in AI search tools (Source: Semrush: SEO Basics, accessed Oct 24, 2026).

How do you set up analytics for free?

Use Google’s help article on setting up Analytics. It is a step-by-step page that explains how to create an account, create a property with a time zone, currency, industry and business size, and add a data stream for a website or an iOS or Android app. It then describes three ways to add the Google tag to a site: through a CMS integration, by pasting the tag into your pages, or through Google Tag Manager (Source: Google Analytics Help: Set up Analytics, accessed Oct 24, 2026).

Do this early. Measurement only helps from the day it is switched on, and the other resources on this page are easier to apply once you can see what visitors actually do on your site.

The article describes the setup, not what to measure or how to read the reports. For that, pair it with a course such as HubSpot Academy or Google Skillshop, described in the next section, or with a tool from the analytics category of the directory.

Which free courses cover marketing more broadly?

Three sites offer courses beyond SEO, and they differ in how much I could confirm.

HubSpot Academy offers on-demand courses organised by role and topic, plus certifications such as Inbound, Social Media, Email Marketing and Content Marketing. The site describes its training as free and online (Source: HubSpot Academy, accessed Oct 24, 2026). It is unclear from the landing page whether an account is needed for every course.

Google Skillshop offers self-paced courses taught by Google product experts, and some lead to product certifications. The areas listed include Google Ads, Google Marketing Platform, Google Analytics, Google My Business, Ad Manager and AdMob. The landing page does not state the cost or whether a sign-in is needed. I have not re-verified this entry, so check the site before planning around it.

Mailchimp Marketing Resources gathers how-to articles, downloadable reports, case studies, tutorials and on-demand webinars, and links to Mailchimp Academy courses. The page does not say which items are free or which need a form or account, and I have not re-verified it.

What free tools and references help with planning and research?

Two HubSpot pages are useful for planning, and both are free to use.

Make My Persona turns a short description of your ideal customer into a structured buyer persona. You describe the customer and answer a few questions, and the tool fills in demographics, goals, pain points, information sources and communication preferences. You can edit the fields, then export the result as a PDF or share it by link. HubSpot describes the tool as completely free, with no subscription or credit card needed, and the page saves up to three personas at a time. Whether an account is required is not stated (Source: HubSpot: Make My Persona, accessed Oct 24, 2026).

HubSpot Marketing Statistics and Trends collects figures by topic: SEO, content, social media, video, email, lead generation, advertising, marketing technology and sales. The 2026 edition draws mostly on HubSpot’s State of Marketing Report, with other figures from sources such as Statista, DataReportal and Wyzowl (Source: HubSpot: Marketing Statistics and Trends, accessed Oct 24, 2026).

It is a quick place to find a cited figure. Check the original source before you reuse a number.

How do you choose between them?

Pick by the job in front of you, not by the publisher. Work down this list and stop when you have enough to act on.

Doing one resource properly beats opening all nine. Pick the first step that matches where you are, and come back to the rest when you need them.

What should you watch out for with free resources?

Free resources are written by organisations with something to sell, and that shapes what they say. The Semrush article, for instance, also promotes Semrush’s own paid tools, so its recommendations are worth reading with that in mind.

Three habits help:

• Check the date. Search and analytics products change often. A page with no visible date, or an old one, needs a second source.
• Follow statistics back to the source. A compiled statistics page is a starting point. Open the original report before you quote a figure to a client or put it in a deck.
• Separate learning from buying. Finishing a vendor’s course does not mean you need the vendor’s product. Use the course for the method and decide on tools separately.

Where should you go next?

Once you have the basics, move from reading to doing. Choose one job, such as getting found locally, and apply it to your own site for a few weeks before you start another.

If you are not sure which type of business plan fits you, start with what this site is and how to use it, or read a full guide for your business type, such as digital marketing for dentists or digital marketing for lawyers.

When you are ready to pick software for a specific job, browse the tools directory, the categories or the use cases. Each listing links to the vendor’s official site and shows the date its facts were last checked.
