Tools Seobook

Quick keyword discovery – paste a URL or a topic and within seconds you get a list of related terms. I tested a page about 'vegan protein powder' and got 50 long-tail suggestions in under three seconds. That speed beats opening a full suite like [Ahrefs](/ahrefs/) for a quick brainstorm when you just need ideas to expand a cluster.

Page comparison – this is the feature I use most. Enter two URLs and it shows their titles, meta descriptions, and common two- and three-word phrases side by side. I ran a comparison between my client's landing page and a competitor's. The competitor had 'free shipping' in their meta description while my client didn't. That took two seconds to spot. I now open the tool before writing any new page to see what the ranking page covers that mine misses.

Keyword density checker – I've stopped treating this as a target, but I still use it as a rough sanity check. If I'm writing about 'best running shoes' and the density hits 8%, I know the text is stuffed. I rewrite until it sits around 2–3%. The number itself means nothing to Google, but it flags when I've gone overboard.

Lightweight and fast – no registration, no installation, no account needed. I can pull it up on a client's laptop during a meeting and run a check without logging in. The spartan interface is actually a relief after the bloated dashboards of commercial tools.

Keyword density as a ranking factor – this is the mistake I made early in my career. I optimised a page to hit 5% density for 'plumber London' and watched the page drop from position 6 to 12. Google doesn't calculate density. The tool shows a text-analysis metric, not a ranking signal. I now use it only to catch accidental stuffing, never as an optimisation target. If you see a guide telling you to hit a specific percentage, ignore it.

Modern rank tracking – the old Rank Checker was a Firefox extension that hasn't been updated in years. SERPs are personalised, location-based, and dynamic. I tried running it for a London-based client and got different results on three consecutive runs. You cannot make campaign decisions on that data. Use a dedicated [rank tracker](/rank-tracker/) or, even better, rely on Google Search Console's first-party impression data.

All-in-one SEO – SEOBook is a collection of utilities, not a platform. There is no backlink analysis, no site audit, no crawl visualisation. I once tried to piece together a full workflow using just these tools and ended up with five tabs open, manually cross-referencing data. It's not efficient. For technical audits you need something like [Screaming Frog](/screaming-frog/), and for competitive backlink research you need a subscription tool.

Surface-level data – the page comparison shows common phrases but gives no search volume, trend, or competition metrics. I compared two pages and saw they both used 'organic cotton', but I had no idea whether that term had any search demand. You need a keyword research tool to go deeper.

Ahrefs for keyword research and backlink analysis. It's paid but I consider it the best value for serious work. I use the Content Gap feature to find terms that competitors rank for that I don't. SEOBook's page comparison is a free, lightweight version of that – but it lacks volume data and backlink profiles. If you do monthly SEO work, budget for Ahrefs.

Semrush for competitive research and PPC data. I've used it to reverse-engineer a competitor's paid ad strategy. The domain overview report is faster than digging through SEOBook's tools. For organic work I still prefer Ahrefs, but Semrush wins for advertising intel.

Google Search Console – non-negotiable and free. It shows exactly what Google crawls, indexes, and ranks for your site. I check impressions and clicks before I open any third-party tool. SEOBook cannot replace first-party data.

Keywords Everywhere browser extension – cheap and integrates where I browse. I see search volume, CPC, and trend data right in the SERP. For under ten dollars, it's a better complement to SEOBook than buying another suite.

Moz for domain authority and spam score. I don't love the metric, but clients expect it. SEOBook doesn't offer any domain-level authority signal. If you need to report a benchmark, [Moz](/moz/) gives you something consistent across industries.

Screaming Frog for technical crawls. SEOBook has no crawler. I run Screaming Frog to find broken links, duplicate titles, and missing alt text. The two tools work well together: SEOBook for quick content checks, Screaming Frog for site structure.
