The best free online marketing tools

1. Canva

Images are of extreme importance to catch people's attention when scrolling through social media feeds. People are more likely to remember information after three days if a relevant image is paired with this information. Add images to a message and viewers will be 65% more likely to remember, compared to when they only hear information (10%). Canva is a free tool that allows users to create compelling images for social media. Users can choose different backgrounds, add filters, text overlay, create infographics and more. You can also use templates to create posters, banners, business cards, etc.

5. Phrase Builder

Phrase Builder will be your best friend whenever you need to come up with a long list of keywords but are feeling uninspired. You just need to create two sets of sentences that are related to the topic you are working on and Phrase Builder will create a list with a variety of keywords by mixing the two sets of sentences. Use a keyword explorer to check which combinations represent a better opportunity and, voilá, you will be ready to produce great content to reach your target audience.

6. Moz keyword planner

Moz is a reference in the SEO world. The company has a paid proprietary software but allows you to try their tools for free online. The Moz keyword planner is one of these tools. You can research up to two keywords a day and get a report suggesting other similar keywords, detailing the strength and search volume for each one. Besides offering SERP analysis, it offers a list of mentions of a certain topic and data on the opportunity available for the keyword.

7. Facebook's free text overlay tool

This tool allows you to test your advertisement’s image before it runs to ensure it has the right proportions. This is important because too much text negatively affects how well the ad reaches your intended audience. The Facebook Text Overlay Tool was more helpful back in the day when Facebook ads could only be 20% text. Many advertisers will be happy to know that this rule was changed months ago. However, the 20% rule shouldn't be overlooked. While you may be able to run an ad with more than 20%, its reach may be significantly lowered.
