A founder's SEO workflow, in order
Run these four steps in sequence and this page covers the whole early-stage SEO job. Nothing here needs a budget, only an afternoon at a time.
Know where you stand
Check your site with the Domain Rating Checker, then read what Domain Rating actually measures so the number cannot mislead you. A low score on a young domain is normal, not a verdict. Check monthly: DR moves slowly, and day-to-day changes are noise.
Audit a page and fix what fails
Run your homepage through the SEO Checker. Every failing check names the problem and links to the generator that fixes it: title tags, meta descriptions, Open Graph tags, FAQ schema. Because most sites share a layout across pages, auditing one page per template covers the whole site in a few runs. Our SEO checklist has the page-by-page version if you want to go deeper.
Build authority deliberately
Rankings are decided mostly by backlinks, so treat link building as a weekly habit rather than a launch-week sprint. Rank your submission targets with the Bulk Domain Rating Checker, start from our verified directory list, and confirm the links you earn are dofollow, because the other kind passes nothing.
Show up where AI answers
A growing share of product discovery now happens inside ChatGPT, Perplexity, and Gemini, where there are no blue links to rank for. The mention trackers show whether the assistants know your brand exists, and how to get your startup recommended by LLMs covers how to change the answer when they do not.
Learn the language first
Every tool on this page is easier to use well when the vocabulary is clear. These plain-English explainers cover what each metric actually measures, what counts as good, and the mistakes the numbers tend to hide.
Frequently asked questions
Are these tools really free?
Yes. Every tool is free with no account and no credit card. The AI generators have a fair-use limit per hour so the collection stays free for everyone; the Domain Rating Checker and the calculators have no limits.
Is there any limit on the AI tools?
Only a fair-use one: each AI run costs real compute, so there is an hourly cap per visitor. Normal use never hits it, and results for the same input are cached so re-running is instant.
Do I need an account?
A free account is required for the AI generators, which is what makes the one-free-run system work. Calculators and the Domain Rating Checker work without logging in.
Which tool should I start with?
The Domain Rating Checker. It takes ten seconds, shows where your site stands today, and tells you whether your priority should be authority building or on-page fixes. From there, the title tag and meta description generators are the highest-leverage next step.
What is a good Domain Rating for a startup?
New domains start at or near zero, and that is normal. Most early-stage startup sites sit somewhere between 0 and 20 in their first year. Getting past 30 usually takes months of consistent backlink building through directories, launches, and content.
How accurate is the Domain Rating Checker?
It pulls live data from Ahrefs, the same source most SEO professionals use. DR moves slowly, so checking monthly is enough; day-to-day changes are mostly noise.
What do the AI mention trackers actually check?
They send six real questions to the engine, four about your category that never mention you and two about your brand by name, and show you the actual answers: whether you were named, next to which competitors, how you were described and, for Perplexity and Gemini, which sources were cited. Read the full method in our guide to tracking brand mentions in ChatGPT, Perplexity and Gemini.
Will AI-generated meta descriptions or titles hurt my SEO?
No. Google does not penalize metadata for being AI-assisted; it cares whether the tag matches the page and earns the click. Treat the generated options as strong drafts, pick the one that fits your page best, and adjust a word or two so it sounds like you.
How do I add the generated tags and schema to my site?
Title tags, meta descriptions, and Open Graph tags go in the <head> of your page; every framework and CMS has a field or component for them. The FAQ schema output is JSON-LD: paste it into a script tag anywhere on the page and validate it with Google's Rich Results Test.
Can I suggest a new tool?
Yes, and we ship fast. Send ideas through the contact page or the community feed; several tools in this collection started as user requests.
