Every one of these gets recommended by someone with a stake in you buying it. Most of them you will open twice and never again.

The concepts underneath are in list of things about the web. This list assumes them.

Grouped by what they do, not by price.

storing and publishing

1. Git

Version-tracking software that runs on your own laptop. Not a website. Nothing to log into.

The problem it solves: homepage-final.html, homepage-final-2.html, homepage-FINAL-actually.html. Git replaces all of that with one file and a history behind it.

You take a snapshot whenever you finish something, and attach a note explaining what changed. In practice that is three commands:

git add .              stage everything you changed
git commit -m "fixed the pricing table"
git push               send it to GitHub

git add . marks which changes belong in this snapshot, the dot means all of them. git commit takes the snapshot and attaches your note. git push uploads it.

The message matters more than it looks. Six months later, "fixed the pricing table" is how you find the moment something changed. "update" and "asdf" are how you lose an afternoon.

Do you need it? Yes, and you already have it whether you know it or not. Anything that deploys from a repo is running Git underneath.

2. GitHub

The online copy of that folder, plus its whole history.

The cleanest analogy: Git is Word's track changes, GitHub is Google Drive. One records what changed, the other stores it somewhere that is not your laptop and lets other people reach it.

The vocabulary, now that it means something:

Term	What it means
Repository (repo)	The project folder, with its history attached. One site, one repo
Commit	One snapshot plus its note
Push	Send commits from your laptop up to GitHub
Pull	Fetch changes someone else pushed. The opposite of push
Clone	Download a repo onto a new machine
Remote	The GitHub copy, as referred to from your laptop. Usually nicknamed origin
Branch	A parallel copy for experiments
Pull request	"Please merge my branch into the main one"

Branches. Your history is a line of commits. main is the default line, and it is the one that goes live. To redesign something without risking the live site, you create a branch, a parallel line that splits off from main. You commit freely on it. main is untouched the whole time. When it works, you merge back.

main      ●───●───●───────────●
                   \         /
redesign            ●───●───●

Merge conflict is the one scary-sounding term, and it is not scary. Two branches changed the same line of the same file and Git will not guess which one you meant. It shows you both and you pick. That is the whole thing.

Do you need it? Yes. It is free for what you will do, and it is what your host reads from.

3. Vercel

The shopfront. It watches your GitHub repo, and every push to main triggers an automatic rebuild and redeploy.

You never upload anything to Vercel. You only ever push to GitHub.

What you will actually use in the dashboard:

Build logs. When a deploy fails, the reason is here. Read it before you guess.

Preview deployments. Every branch gets its own private URL, built automatically. Check the redesign on a real phone before it goes public.

Environment variables. API keys and passwords must never sit in your code, because your repo may be public and everything you commit is permanent. You paste them into the dashboard instead, and the code refers to them by name.

Domains. You buy the name from a registrar, point its DNS records at Vercel, and Vercel handles the HTTPS certificate automatically.

Rollback. Every deploy is kept. Find yesterday's, click promote, live in about ten seconds.

One warning worth having in advance: if you use an AI coding tool that can connect to Vercel, authorise that connection. Without it the tool can see that your live site is serving something stale but cannot see why, because it has no access to the build logs. That turns a five-minute diagnosis into an unanswerable question.

Do you need it? One of Vercel, Netlify, or Cloudflare Pages. Not all three.

4. Netlify and Cloudflare Pages

The same job as Vercel, from different companies. All three watch a repo, build on push, serve globally, and have a free tier that covers a personal site comfortably.

Vercel is the natural fit if you are on Next.js, since the same company makes both. Cloudflare Pages has the most generous free bandwidth. Netlify has the friendliest forms and redirects.

Do you need them? Only as an alternative to Vercel. There is no reason to run two.

measuring, the free first-party layer

This is the section that matters. Everything here reports what actually happened on your site, and all of it is free.

5. Google Search Console

The single most valuable tool on this list, and it costs nothing.

You verify you own the domain, and Google shows you its own records of your site. Not an estimate. Its records.

Performance. every query real people typed that showed your page, with impressions, clicks and average position. Filterable by page, country, device. Exportable, though it truncates at 1,000 rows, which matters more than it sounds.

Pages. how many URLs were crawled, how many were indexed, and the specific reason each excluded page was excluded. This is where you diagnose the crawl/index/rank distinction. When a page ranks nowhere, this report tells you whether it is a ranking problem or whether the page was never indexed at all.

Sitemaps. submit it here, check it was read.

URL inspection. paste any URL, see exactly what Google has stored for it, and request a re-crawl.

Data goes back 16 months. Export it before that window rolls.

Do you need it? If you have a website and you do not have this, set it up today. There is no substitute and no paid tool that replaces it.

6. Bing Webmaster Tools

The same idea for Bing, plus one thing Google does not give away: free keyword research with actual volume numbers.

Bing's index is smaller, so its traffic data matters less. But the keyword tool is genuinely useful, and it is the free answer to "what should this page target" when you have no first-party data because the page does not exist yet.

It also matters more than its market share suggests, because Bing's index is what several AI answer engines read from.

Do you need it? Yes. Free, ten minutes to set up, and it fills the one gap Search Console leaves.

7. Google Analytics 4

Search Console tells you how people arrived. Analytics tells you what they did after arriving. Pages per visit, time on page, where they left, what they clicked.

Two honest caveats. GA4 is markedly harder to use than the version it replaced, and its numbers will not match Search Console's, because they count different things at different points. Do not spend an evening trying to reconcile them.

Do you need it? Only if you will act on behaviour data. For a list blog, arrival data answers most of your questions and this is optional.

8. Plausible and Fathom

Lightweight alternatives to GA4. No cookies, no consent banner needed in most jurisdictions, one screen that loads instantly and is readable without training. Paid, roughly $9–14/month.

The trade-off is depth. You get visitors, sources, top pages, and very little else.

Do you need it? If GA4 has defeated you and you would actually look at a simpler dashboard, this is money well spent. If you would not look at either, save it.

9. Vercel Analytics

Built into the host. Visitors and page views with no extra script, plus Core Web Vitals measured on real visits rather than simulated ones, which is the part the free alternatives cannot give you.

Do you need it? The free tier is worth switching on. Do not pay for the upgrade until the free one has told you something you acted on.

auditing, the paid platforms and their free doors

10. Ahrefs Webmaster Tools

The one genuinely free door into a paid platform, and almost nobody uses it.

Verify a domain you own and you get Ahrefs' site audit, so broken links, redirect chains, missing metadata and slow pages, plus its backlink index for that domain. Free, permanently, for verified sites only.

Do you need it? Yes. It is the best free technical audit available and it takes fifteen minutes to set up.

11. Ahrefs

The full platform, from $129/month. The strongest backlink index in the industry, which is the one thing it is genuinely best at.

A backlink index is a vendor's own stored crawl record of every link between pages it has found. Ahrefs crawls more, more often, so it finds links others miss and notices dead ones sooner.

Google will not tell you who links to a competitor. Nobody will, for free. That is the entire reason this product costs $129 a month, and it is the only reason.

Do you need it? Not for your own site, Webmaster Tools covers that free. Only when competitor backlink research becomes a job you do weekly.

12. Semrush

The broadest platform. Keyword research, rank tracking, site audit, competitor analysis, content tools, ads data.

Tiers as of August 2026: SEO $139, Starter $199, Pro+ $299, Advanced $549.

The API trap is worth knowing before you get excited about automation. There is no free API tier. API access requires the Advanced plan at $549/month, and that plan includes zero API units. Units are bought separately at roughly $50 per million and expire monthly. Realistic floor to make your first API call: around $600.

The free account is a demo, not a tool: one site, ten keywords, 100 URLs a month, about ten requests a day.

Do you need it? Almost certainly not. It is priced for agencies billing clients for the output.

13. SE Ranking

The same categories as Semrush and Ahrefs with thinner data, from $44/month. API access included at a much lower tier.

Do you need it? If you have genuinely concluded you need a platform and $139 is not happening, this is the sensible compromise. Start by concluding you do not need a platform.

14. Screaming Frog

A desktop crawler. You run it on your own machine, point it at your site, and it walks every page the way a crawler does, reporting status codes, redirect chains, duplicate titles, missing metadata, orphan pages, broken links.

Free up to 500 URLs. £199/year beyond that.

It is the single best tool for the question "what is actually wrong with this site, structurally". It does not do keywords, rankings or backlinks. It only crawls, and it crawls better than anything else.

Do you need it? If your site is under 500 pages, the free version is excellent and you should run it once a quarter.

diagnosing, free and no account

15. Lighthouse and PageSpeed Insights

The same engine, two doors. Lighthouse is built into Chrome. Open DevTools, Lighthouse tab, run. PageSpeed Insights is the web version.

You get scores for performance, accessibility, best practices and SEO, plus specific fixes ranked by how much time each would save.

PageSpeed Insights adds one thing Lighthouse cannot: field data from real Chrome users who visited your site, alongside the simulated lab test. When the two disagree, the field data is the truth.

Do you need it? Run it after any significant change. Free, no account, thirty seconds.

16. Rich Results Test and the Schema Validator

Schema is structured data you add to a page, a machine-readable block declaring "this is a product, this is its price, this is its rating", that helps engines display your page as something richer than a link.

These two tools tell you whether yours is valid and what it would produce. Free, no account.

Do you need it? Only when you have added schema. Then, yes, every time, because invalid schema is silently ignored, so you get no error and no benefit.

---

raw data, the APIs

17. SerpApi, Serper.dev and DataForSEO

Three services doing the same job. They fetch a search results page and hand it back as JSON instead of HTML, sold by the call rather than by the month.

DataForSEO is the one to pick if you are picking one. $0.60 per 1,000 SERPs, $50 minimum deposit, and unlike the other two it sells both SERP data and keyword volume from the same account. It has an open-source MCP server, so an AI coding tool can query it directly.

Serper.dev is the cheapest way to try the idea. 2,500 free queries, no card. Watch two things: asking for 11 to 100 results costs two credits rather than one, and credits expire after six months.

SerpApi is the most expensive of the three. 250 free searches a month, then $25 per 1,000. Unused searches are wiped at renewal, and running out early triggers an early renewal, so you pay the full plan again.

Do you need any of these? Only if you are building something that runs on a schedule. For looking things up by hand they are the wrong shape entirely.

the honest summary

If you have a website and no budget, the stack is:

Search Console + Bing Webmaster Tools + Ahrefs Webmaster Tools + Lighthouse + Screaming Frog free tier.

That is five tools, all free, and together they answer every question about a site that already exists.

The only gap they leave is choosing target queries for pages that do not exist yet, because none of them can show you data for a page you have not written. Bing's keyword tool fills most of that, free. DataForSEO fills the rest for a few dollars.

The $139-to-$549 platforms are not a scam and they are not useless. They are priced for people who audit fifty domains they do not own. Buying one to check your own site is paying a subscription for a worse version of a report Google gives you for nothing.
