SEO Tools for a Small Blog: What You Need and What to Do With Each One Every Week

A small blog, one person publishing four to eight posts a month, needs four kinds of SEO tool: Google Search Console, a keyword tool, an on-page helper and an AI assistant. Two of those can be free forever. The other two can be free until your publishing rhythm gives you a reason to pay.

The problem is rarely a missing tool. It is having six logins and no routine. So this post does two things: it names the tool for each job, and it tells you what to do with each one every week. Then it shows three stacks at €0, about €50 and about €150 a month, and the signal that tells you when to move up.

All prices below were checked on the vendors' own pricing pages in September 2026. SEO pricing changes often, so check again before you buy.

The four jobs, and the tool for each

Think in jobs, not brands. A small blog has four SEO jobs:

1. See what you already rank for. Your own data.
2. Check demand for new topics. Other people's searches.
3. Make each page complete. Title, headings, answer, links.
4. Do the thinking work faster. Clustering, briefs, outlines, rewrites.

Here is what covers each one, and what it costs.

Job 1: Google Search Console (free)

Google Search Console is the only SEO tool that shows your real data: the queries you appear for, your clicks, impressions, click-through rate and average position. The Performance report keeps 16 months of history. It is free, and no paid tool beats it for your own site, because paid tools estimate and Search Console measures.

What to do with it every week: open Performance, set the range to the last 28 days, and look for queries with impressions but few clicks at average position 8 to 20. Those are your near-wins. A page that already sits on page one or two for a query is much cheaper to push up than a new page is to start. Our guide to keyword research with free tools walks through the filters step by step.

Job 2: a keyword tool (free to start)

Search Console only knows about queries you already show up for. For new topics you need demand data from outside your site. Two free options cover a small blog:

• Google Keyword Planner. Free, inside Google Ads. You need to finish setting up a Google Ads account first, and switch it to Expert Mode if it opened in Smart Mode. It gives keyword ideas and search volume estimates, built for advertisers but useful for bloggers.
• Ahrefs Free (formerly Ahrefs Webmaster Tools). Once you verify your site you get Site Audit (5,000 crawl credits per project a month), Site Explorer for your own keywords and backlinks, and web analytics. It is about your own site, not your competitors.

If you want competitor keyword data without a full suite, Ahrefs also lists a Starter plan at €27/month, which it pitches for seeing what people search and looking at competitors.

What to do with it every week: take the two or three topic ideas you have for next week and check that people actually search for them. You are not hunting for big numbers. For a small blog, a specific question with modest demand beats a broad term you cannot rank for.

Job 3: an on-page helper (a checklist first)

On-page work is making each post complete: one search intent, the answer in the first 100 words, a title that matches how people phrase the search, descriptive headings, internal links in both directions and an FAQ built from real questions.

You do not need software for that at first. You need a checklist and fifteen minutes per post. Ours is the on-page SEO checklist for small sites, twelve checks you run before you hit publish.

Software earns its place once you publish every week. A content optimizer like Surfer scores your draft live against the pages that already rank for your term: structure, terms, headings, length. Its Discovery plan is €49/month billed yearly and covers 120 documents and 10 tracked pages. Treat the score as a guide. Chasing a perfect number makes prose stiff.

What to do with it every week: run every draft through the checklist (or the optimizer) before it goes live, and run one older post through it as well.

Job 4: an AI assistant (free or about $20/month)

An AI assistant does the thinking work that paid SEO tools charge for: grouping 200 queries into clusters by intent, turning a query list into a brief, drafting an FAQ from real questions, suggesting sharper titles. We use Claude and ChatGPT for this.

Both have free plans. Claude Pro is $20/month billed monthly ($17/month billed yearly). ChatGPT Plus is $20/month, and ChatGPT Go is $8/month in the US. If you already pay for one of these, it is already your SEO assistant.

What to do with it every week: paste your Search Console export and ask it to cluster the queries by intent and flag which cluster your blog does not cover yet. Then ask it for a brief for next week's post: the question to answer first, the H2s, and the FAQ questions.

A warning that saves you rankings: use the assistant for structure and research, not for publishing pages at volume. Ten answer-first posts you checked yourself beat a hundred thin ones.

The weekly 60-minute SEO routine

Tools without a routine are just subscriptions. Put one hour on your calendar, same day each week. Friday morning works well because the week's data is in.

1. Minutes 0 to 15: Search Console. Open Performance, last 28 days, compare to the previous period. Note three things: the pages that gained clicks, the pages that lost clicks, and your top five near-win queries (impressions, low clicks, position 8 to 20). Write them in one running document.
2. Minutes 15 to 30: next week's topics. Paste the near-win queries into your AI assistant and ask it to cluster them by intent. Pick your next one or two posts from the clusters. Check demand for any new idea in Keyword Planner. Decide the one question each post answers first.
3. Minutes 30 to 45: on-page checks. Run this week's drafts through the on-page checklist or your optimizer. Fix the title, the first 100 words and the headings. Add two internal links from each new post to your most important pages, and two links to it from older posts.
4. Minutes 45 to 60: refresh one old post. Take the page behind your best near-win query and improve it: match the title to the query, answer it sooner, update stale facts with dates, add the missing section or FAQ. Our full method is in how to refresh old blog posts. Request indexing in Search Console when you are done.

That is the whole routine. It works at four posts a month and at eight. What changes as you grow is how much data each step has to chew through, and that is the moment tools start to matter.

Three stacks: €0, about €50, about €150 a month

Here is how the four jobs map to three budgets. Prices checked September 2026, as listed on each vendor's pricing page. Currencies are as the vendor shows them: the AI assistants price in dollars.

Job	Free stack (€0)	About €50/month	About €150/month
Your own data	Search Console	Search Console	Search Console
New-topic demand	Keyword Planner, Ahrefs Free	Keyword Planner, Ahrefs Free	Semrush SEO plan (€134/month billed monthly, €112.52 billed yearly)
On-page	The checklist	Surfer Discovery (€49/month billed yearly)	The checklist, or Surfer if budget allows
Site audit	Ahrefs Free Site Audit	Ahrefs Free Site Audit	Semrush Site Audit
Rank tracking	Search Console average position	Surfer (10 tracked pages)	Semrush Position Tracking (500 keywords)
AI assistant	Claude or ChatGPT free plan	Free plan, or the $20 plan you already pay for	Claude Pro or ChatGPT Plus ($20/month)

A few notes on reading this table.

The free stack is not a demo. Search Console plus an assistant plus a checklist is enough to find near-wins, write complete posts and refresh old ones. Most small blogs lose rankings to missing routines, not missing tools.

The €50 stack buys production, not research. Surfer makes each post you write more complete. That is the right first upgrade when you publish every week and rankings feel random. It is the same call we make in Surfer vs Semrush for small sites: the small-site bottleneck is usually producing pages good enough to rank.

The €150 stack buys research. Semrush's entry plan (called SEO on its pricing page) includes keyword research, competitor analysis, Position Tracking for 500 keywords and Site Audit. That is worth it when you are in a crowded niche and competitor data decides what you write every week. An alternative at a similar price: Surfer Discovery plus Ahrefs Lite (€98.58/month billed yearly, €119 billed monthly, 750 tracked keywords).

Running both suites is overkill for a one-person blog. Semrush plus Ahrefs costs more than most small blogs earn from search.

When a paid tool starts paying for itself

Do not upgrade on a date or a traffic number. Upgrade when a specific question comes up every week and free tools cannot answer it. Four signals:

1. You publish every week and rankings feel random. Posts that you checked against the checklist still stall on page two. An optimizer that compares your draft to what ranks is the answer. Buy Surfer.
2. You do not know what to write next, and you are in a crowded niche. Search Console only shows what you already rank for. When your near-win list runs dry and the obvious topics belong to big sites, you need competitor gap data. Buy Semrush or Ahrefs.
3. You track more than a handful of important terms. Search Console's average position is fine for a few pages. When you care about fifty terms, a rank tracker saves real time.
4. The blog makes money. If one extra ranking post a month is worth more than the subscription, the math is simple. If it is not, the money does more in your content budget.

If none of these fire, stay free. There is no prize for owning the tools.

Tools a small blog can skip for now

Some tools are good and still wrong for a one-person blog at four to eight posts a month:

• A full suite before you publish weekly. You would pay for the whole department and use a fifth of it.
• Several keyword tools at once. They estimate differently. Pick one and learn its quirks.
• AI writing tools that publish at volume. The assistant you already have writes better briefs than a one-click article generator writes posts.
• Link-building services. Buying links is against Google's spam policies and a risk a small site does not need.

Start this week: the 15-minute version

No time for the full routine yet? Do this today:

1. Open Search Console, go to Performance, and set the date range to the last three months.
2. Click the Queries tab, turn on Average CTR and Average position, and sort by Impressions.
3. Write down five queries at position 8 to 20 with impressions but few clicks.
4. For the page behind the top query, rewrite the title so it matches the query's wording and move the direct answer into the first two sentences.
5. Request indexing, put a reminder in your calendar for four weeks from today, and compare.

That is one near-win improved with one free tool. Do it every week and you have an SEO practice. For the full picture of which tools cover content and search in 2026, see our AI content and SEO tools hub, and for the whole month-by-month path, the plan rank in Google with a small site.
