Is Semrush Free Tier Enough for a New Blog?

The short answer: yes — for the first 3 to 4 months of a new blog,
Semrush's free plan is sufficient. Ten keyword searches per day is
more than enough when you are publishing one or two articles per week.
The free tier becomes a genuine constraint only when your publishing
pace increases past two articles per week or when you need ongoing
site audit data.

Here is what the free plan actually gives you, what it does not, and
the exact point where upgrading makes financial sense.

What Semrush Free Tier Gives You

The free plan at semrush.com includes:

• 10 keyword searches per day — enter a keyword and see its
  monthly search volume, keyword difficulty score, and the top
  10 ranking pages
• 1 domain tracked — you can track your own site's ranking
  positions for up to 10 keywords
• Limited site audit — crawls up to 100 pages of your site
  to identify basic technical SEO issues
• 1 project — one active campaign covering your site

For a new blog targeting 1–2 articles per week, the maths works.
Each article needs one target keyword. Ten searches per day means
you can research 10 potential keywords per day — more than enough
to plan a full week of content in a single session.

What It Does Not Give You

The free tier blocks access to:

• Keyword Magic Tool in full — the tool that shows thousands
  of related keyword variations is limited on free
• Competitor keyword research — you cannot see which keywords
  a competitor site is ranking for
• Backlink analysis — the link building research tools are
  paid-only
• Historical data — trend data over time is restricted
• Unlimited site audits — the 100-page crawl limit is a
  constraint for larger sites

For months one through four of a new blog, none of these
limitations are critical. You are not yet building backlinks
at scale, you do not have a large enough site to audit beyond
100 pages, and competitor research becomes relevant only once
your own content is established.

The Exact Point to Upgrade

Upgrade to a paid Semrush plan when two of these three apply:

1. You are publishing more than 2 articles per week and running
   out of your 10 daily keyword searches
2. You want to analyse which keywords a competitor is already
   ranking for — to find content gaps you can target
3. Your site has grown past 100 pages and you need a complete
   technical audit

The Pro plan starts at $139.95/month (annual rate lower). That
is a meaningful cost for a new blog. Do not upgrade before the
free tier is genuinely insufficient — most new bloggers upgrade
too early and pay for capacity they are not using.

💡 Golden Tip: Semrush offers a free 7-day trial of the Pro
plan with no commitment. Run it when you have a batch of 20+
articles to research — you can extract months of keyword data
in a single trial week before reverting to free.

The Workflow That Works on the Free Tier

The She Made £940/Month blog case study documented on NerdStake
used Semrush's free tier exclusively for the first four months.
The workflow: one 20-minute keyword research session per week,
using 4–6 of the 10 daily searches per article. Remaining daily
searches banked for competitor checks and topic discovery.

At month five — when the publishing pace increased to three
articles per week and competitor analysis became relevant —
the free tier became a constraint and a paid plan was warranted.

The Bottom Line

Free Semrush is enough for months 1–4 of a new blog publishing
1–2 articles per week. Use the 10 daily searches deliberately —
one research session per article, not scattered searches
throughout the day. When you hit the constraint naturally,
time a 7-day Pro trial to a heavy content planning week.
