KNOWLEDGE BASE
SEO knowledge base
Straight answers to the questions people actually ask about SEO — grouped by topic. Start with a theme below.
Keywords & search volume
How keyword ideas, volume, and difficulty actually work — and where free tools fit.
Can I get real search volume for free?
Yes, with a caveat. Google Keyword Planner reports official monthly volume as ranges without requiring an active Ads campaign, and Google Trends shows relative demand and seasonality at no cost. Rule-based generators produce the idea list; Google’s own free tools confirm the numbers.
Why do idea generators skip volume figures?
Volume comes from a licensed clickstream and search index that costs money to maintain — that is the core of what paid platforms sell. A browser tool stays free by generating variations, then handing volume validation off to Keyword Planner or Trends.
Should I bother with terms under 100 searches a month?
Frequently, yes. Specific long-tail phrases convert better and rank faster because competition is thin. Aggregate tools also round small numbers down to “low” or zero, so real demand is often higher than reported — particularly for local and niche queries.
Why does keyword difficulty differ from tool to tool?
Difficulty is a model, not a measurement. Each platform estimates it from its own backlink index and authority formula, so the same term can score very differently. Only compare difficulty scores produced by a single tool.
Meta tags & search snippets
Titles, descriptions, and how Google decides what to display.
Are meta tags measured in characters or pixels?
Google truncates by pixel width, not character count, so two titles of equal length can display differently. Aim titles under roughly 580px and descriptions under about 990px — the counters in our meta tools measure pixels directly.
Why does Google rewrite my meta description?
Google frequently replaces descriptions when it judges a passage from the page a better match for the query. A strong, keyword-relevant description raises the odds yours is kept, but it is never guaranteed — treat it as a strong suggestion.
Does the meta description affect rankings?
Not directly. It is not a ranking factor, but it heavily influences click-through rate, and click behavior does feed back into performance. A compelling description earns clicks even when it does not move rankings on its own.
Crawling, indexing & AI bots
robots.txt, llms.txt, and controlling who reaches your site.
What is llms.txt and do I need one?
llms.txt is an emerging plain-text file that tells AI engines what your site is about and which pages matter, helping them summarize and cite you accurately. It is optional and early-stage, but low-effort to add and increasingly worthwhile as AI search grows.
Should I block AI crawlers in robots.txt?
It depends on the bot’s job. Blocking training crawlers like GPTBot or CCBot stops your content feeding model training, but blocking answer or search crawlers such as OAI-SearchBot or PerplexityBot removes you from AI answers entirely. Separate the two decisions deliberately.
Does robots.txt remove a page from Google?
No. Disallow only asks crawlers not to fetch a page; a blocked URL can still be indexed from links. To keep something out of the index, allow crawling and use a noindex tag, or restrict access — not robots.txt alone.
Canonicals, redirects & hreflang
The technical tags that prevent duplicate content and route users correctly.
When should I use a canonical tag versus a redirect?
Use a canonical when both URLs should stay reachable but one is the master version — such as filtered or tracking variants. Use a 301 redirect when the old URL should no longer exist and every visitor and signal should move to the new one.
What is the difference between a 301 and a 302?
A 301 is permanent and passes ranking signals to the destination — use it for moved or merged pages. A 302 is temporary and tells search engines the original will return, so it does not consolidate signals the same way.
Do I need hreflang for a multi-country site?
If you publish similar content for different languages or regions, hreflang tells Google which version to show which audience, preventing the wrong-country or duplicate-content problem. Every version must reference every other, including an x-default fallback.
Content length & readability
Word counts, character limits, and what actually matters for SEO.
Is there an ideal word count for ranking?
No fixed number. Length should match intent — a definition needs a paragraph, a buying guide needs depth. Longer content often ranks because thorough coverage earns links and satisfies more queries, not because word count itself is a factor.
Why do character limits matter per platform?
Each surface truncates differently — a title tag, a tweet, and a Facebook post all cut off at different points. Writing to each platform’s limit keeps your message from being clipped mid-sentence where it matters most.
Using these free tools
How the suite works, and what “free” really means here.
How are these tools free with no sign-up?
Every tool runs entirely in your browser with rule-based logic and no server calls, so there is no per-use cost to pass on. That is why there is no account, no usage cap, and no watermark — the economics simply do not require them.
Do the tools work on mobile?
Yes. The whole suite is responsive and runs in any modern mobile browser with no app to install. Because processing happens on your device, results appear instantly even on a phone.
Is my data sent anywhere?
No. Since the logic executes in your browser, what you type into a tool is not uploaded to a server. Your content stays on your device.
