In the world of SEO, it is commonly accepted that SEMrush is among the most powerful tools available and that it uses a range of features covering all SEO optimization needs. It’s an all-in-one tool, as powerful in keyword research and keyword suggestions as it is in thebacklink analysis.
But SEMrush is not the only tool available for SEO: there are many other tools, different from SEMrush and at a lower price (and sometimes completely free).
At the end of SEMrush's trial period, you must pay a monthly subscription to continue benefiting from its features. Depending on the functions you want in your dashboard, the price starts at €69 per month.
Often, at the end of the free version, many users look for alternatives to Semrush not because they're dissatisfied, but because they have to pay — and rather expensively at that. Among the alternatives, these users may find a plethora of software, but rarely as effective as this one, and they may need to combine several tools…
So here is a selection of tools that, in at least some respects, can replace SEMrush.
Free alternatives to SEMrush
1. UpCity

The "SEO Report Card" from UpCity analyzes your site to see how it compares to its competitors. Small businesses seeking simple, easy-to-understand metrics to evaluate the success of their SEO strategy may find it sufficient.
For a free tool, it still provides fairly in-depth data on your site's ranking (across several search engines), as well as on the success of your keyword strategy.
The platform also provides trust metrics and information about site accessibility, allowing the user to evaluate key data such as your site's authority level and its loading time.
2. Neil Patel’s Ubersuggest

From Neil Patel, one of the most prominent thought leaders in the field, Ubersuggest is a free tool with basic attributes comparable to Google Keyword Planner, although somewhat different: indeed, unlike Google Keyword, Ubersuggest it displays only 3 metrics: the search volume associated with the query, the PPC price (CPC) and the ranking difficulty, but all three are fairly accurate and similar to SEMRush.
In addition, it recently created a new attribute «Content ideas», where it will suggest topic ideas, as well as useful metrics such as the number of backlinks created by identical articles and estimated monthly visits.
Compared to SEMRush or Google Keyword Planner, it doesn't give many keyword ideas. You can however search for your keyword suggestions in Google Keyword Planner and replicate them on Ubersuggest to get more accurate metrics (and article suggestions).

Conclusion
SEMrush is often considered the gold standard among SEO platforms. However, if you are new to the field, its high cost can be prohibitive, and the huge number of features and tools can overwhelm a beginner.
That said, even for an experienced SEO professional, it can be worthwhile to review the competition to see if there are new features you may be missing.
Before making a decision, think about the features you need most, the number of sites you will monitor, the size of your team, and your SEO budget.
And of course, before committing to a subscription, don’t forget to take advantage of all the free features and trial periods. Once you’ve found a platform that fits your business, go for it, but still keep an eye on alternatives.
You can also delegate the management of your SEO to a freelance SEO consultant. That way, you won’t have to find SEO tools yourself: your provider will take care of them and deliver the results of their analyses and recommendations directly to you.
