Tool FAQs
- Are these SEO tools free?
- Yes. All tools on this page are free, need no sign-up, and run entirely in your browser — nothing you type is sent to a server or stored.
- Do I need an account to use them?
- No. There is no login, no email wall, and no usage limit.
- Which tool should I use first?
- If you are planning a campaign, start with the ROI calculator. If you already have links, run the anchor text checker to spot over-optimisation before it becomes a ranking problem.
- Where does the anchor text checker get its safe ratios?
- The ranges reflect commonly observed healthy profiles: roughly 40–60% branded, 20–30% generic or naked URL, and under 10% exact-match commercial anchors. They are directional benchmarks, not thresholds Google publishes.
- How accurate is the meta previewer?
- It approximates Google's rendering using pixel-width estimates for the default desktop result. Actual truncation varies by device, query, and whether Google rewrites your title.
- Can I use the outputs in a client report?
- Yes, with attribution to guestpostwebsite.com. Treat calculator outputs as directional estimates rather than guarantees.
- Are more tools coming?
- Yes — tools are added based on what readers ask for most. Tell us what you need through the contact page.
