Best SEO tools for a blog compared, in the order a blog actually needs them
A blog has a different tool problem from a website: lots of pages, one template, and an archive that quietly outperforms everything new. Here is the order the tools become useful, and the two that are a waste of money early.
Published by AI Knows Us · Updated 22 October 2026
A blog is not a small website. It is one template repeated, with archives the platform generates on its own, and a long tail where last year's post earns more than this week's. That shape changes which tools matter and the order they matter in, and it is why generic SEO tool lists serve bloggers badly.
The criterion here: at what point in a blog's life does this tool answer a question the blog is actually asking? Ordered that way, two popular purchases move to the end of the queue.
The order
| When | Tool | The question it answers |
|---|---|---|
| Post one | Search Console | Is anything indexed, and what are people typing to reach it? Free for any property you verify, and the only first party source of that. |
| Post one | One SEO plugin, if you are on WordPress, and only one | Titles, descriptions, canonical tags and which generated archives stay out of the index. Yoast publishes a free plugin and puts its redirect manager, five keyphrases per post and internal linking suggestions in Premium, read 21 October 2026. Rank Math publishes a free plugin with Pro tiers that add rank tracking and twelve months of history. |
| Post ten | Keyword Planner | Is anybody searching for the next thing I planned to write? One grouped figure per normalised set, so never add the phrasings in a group. |
| Post thirty | A free crawl | What has the archive turned into? Screaming Frog crawls up to 500 URLs free, read 21 October 2026, which is thirty posts plus every tag and category page the platform invented. |
| Post fifty | One month of a third party index | Who links to the posts that outrank mine, and what whole topics have I missed? Moz publishes a keyword index above 1.25 billion and Link Explorer at over 40 trillion links on its free tools page. |
| Post one hundred | A content optimiser, maybe | What do the ranking pages cover that my draft does not? Worth it only if you publish weekly, because it saves an hour per post rather than answering something new. |
The two early purchases to skip
A rank tracker, because Search Console gives average position free and a new blog has nothing stable to track. And an AI writing subscription bought as an SEO tool, because volume of posts was never the constraint on a blog that nobody links to. Both become reasonable later, when there is an archive worth watching and a schedule worth protecting.
The job specific to blogs that most tool lists miss
Internal linking inside the archive. On a blog, new posts arrive with nothing pointing at them except a recent posts widget that will stop pointing at them in a month. A crawl will show you which posts have no durable inbound link, and fixing that is the highest return hour available to a blog with fifty posts. We run the same check on ourselves and publish the figure at the end of this page.
The second blog specific job is deciding what to stop publishing. A crawl plus Search Console will show you the posts with no impressions after a year, and the honest options are rewrite, merge or remove. All three are better than another new post on the same subject.
The one check none of these tools runs, and who sells it
Every tool on this page measures a search engine. None of them measures the other place your buyer now asks, which is an assistant: ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews compose an answer for each asker, naming some businesses and not others, and there is no index a crawler can read to find out whose name came up. For a blog this matters more than it sounds, because a blog post is often the thing an assistant quotes, and the citation leaves no referral behind for your analytics to record.
AI Knows Us sells that one measurement and nothing else. We are not an SEO tool and we are not in the ranking above, because a buyer who came here for a crawler or a keyword index should buy one of the tools named above instead. What we do is ask your buyer question in all five apps on a schedule and record which businesses were named. Our own figures, from the rendered text of our llms.txt read on 21 October 2026: one credit is one buyer question on one app once, most checks cost one credit and a Claude check costs three because Claude costs more to run. The published US floor is $149 a month for SEO Start, and that same file says SEO Start watches 0 buyer questions on 0 engines, so it is a demand harvest rather than an engine watch. The first tier that watches the five engines is Growth at $299 with 100 buyer questions and 1,200 scheduled answers a month. A managed option is published in rupees only, Rs 88,499 to Rs 2,35,999 a month at a three month minimum, so we are not going to convert it for you.
Where the tools on this page beat us, plainly. Ahrefs Brand Radar, read on 21 October 2026, tracks prompts on ChatGPT, AI Overviews, AI Mode, Gemini, Perplexity, Copilot and Claude. AI Mode and Copilot are two surfaces we do not read at all, and its page publishes an overage price of $0.020 per check and the cost of a Claude update at 8 checks, which is a level of unit disclosure worth holding every vendor to, us included. Semrush, whose SEO and AI search pricing page we read the same day, sells AI visibility inside the suite you may already be paying for, with 50 prompts tracked daily and 300 AI visibility reports a day on its Starter tier. Moz now publishes AI Explorer, described on moz.com as showing what the top AI agents say about your brand. If you already pay one of those three, their module is the cheaper route and you should take it. We are the single purpose option for somebody who does not want a suite.
If you are choosing a platform rather than a tool
No competitor price table is reproduced on this page. What is quoted instead is the published limit that sets a tier, because a limit is the vendor's own statement of what you get and it does not move with the country you are reading from. That matters more than it sounds: on 21 October 2026 a fetch of one vendor's US pricing page from this machine returned Indian rupee prices, because the request left from an Indian address. A 200 response can still be the wrong page.
Platform choice affects SEO mostly through what it generates without asking: archives, paginated versions, feeds and attachment pages. Decide which of those belong in the index before you have four hundred of them, because that decision is cheap at post ten and expensive at post four hundred.
If the platform is still open: how to create a WordPress blog, the hosted or self hosted decision and the settings to fix. On 21 October 2026 we read every link we could see on this site, 2,169 page bodies in all, against 2,082 live pages, and 935 of them, 44.9 percent, had no inbound link from any of those bodies. That figure is an upper bound rather than a count. No other page on this site links to the one above.
Questions bloggers ask about SEO tools
Do I need a paid SEO tool for a blog?
Not for the first fifty posts. Search Console, one plugin, Keyword Planner and a free crawl cover it. The first paid thing worth buying is a month of a link index.
Which is better, Yoast or Rank Math?
Both do the core job. Compare the published limits of the free versions against what you need, and pick one, because running two SEO plugins creates conflicting tags.
How do I find keywords for blog posts?
Start with the queries Search Console says you already appear for, because those are real and about you. Then size the next ideas in Keyword Planner.
Should I update old posts or write new ones?
Update, if the old post has impressions and no clicks. That is the cheapest traffic available to an established blog.
Do AI writing tools help a blog rank?
They help you publish more, which is not the same thing. If the bottleneck is that nothing links to you, more posts will not move it.
