SEO Keyword Tool
Helps you discover, evaluate, and organise search terms so you can target content that matches what people actually type into Google.
If you have ever picked a keyword on a low difficulty score and still failed to rank, you already know the number is not the whole story.
Key points
- Start with a seed keyword, then expand into long-tail phrases and questions.
- Check the live SERP before trusting any difficulty or volume estimate.
- Group keywords by topic and intent, not just by volume.
- Treat keyword tool metrics as signals, not guarantees; even a free keyword tool can give misleading difficulty scores.
- Update your keyword lists regularly because search behaviour shifts.
The same keyword, three different scores
You search for 'best running shoes' in three keyword research tools. Tool A shows 22,000 monthly searches and a difficulty of 68. Tool B shows 18,500 searches and difficulty 74. Tool C shows 25,000 searches and difficulty 55. All three are estimating the same query. The real SERP is dominated by Amazon, Nike, and Runner's World. No tool tells you that the first organic result is a 2023 buyer's guide with 2,000 backlinks. The volume number is roughly right; the difficulty number is a guess.
Three situations where this changes your decision
- High volume, high difficulty A term like 'SEO services' may show 5,000 monthly searches but a difficulty of 92. You will likely waste effort unless you have an authoritative domain and a budget for links.
- Low volume, low difficulty A phrase like 'SEO keyword tool for small business' might have 200 searches but a difficulty of 12. That is often a faster path to page-one visibility.
- Volume drops over time A keyword that had 1,000 searches six months ago may now have 300. Historical trends in the tool catch this before you invest in content for a declining topic.
Four ways it goes wrong
- Ignoring search intent A tool lists popular keywords like 'buy running shoes' and 'best running shoes' with similar volume. The first is transactional, the second is commercial. Targeting the wrong intent wastes the page.
- Trusting difficulty blindly Keyword difficulty is a proprietary estimate. Two tools can give opposite scores for the same query. Always validate against the actual SERP.
- Chasing only head terms Broad keywords like 'marketing' have huge volume but extreme competition. Long-tail variants like 'B2B marketing automation for startups' are easier to rank for.
- Not grouping into clusters Collecting 200 isolated keywords without mapping them to topics leads to thin, disconnected pages. Grouping them into clusters builds topical authority.
What to check before acting
- Live SERP features Check if Google shows featured snippets, knowledge panels, or video carousels. These change the click-through rate and the type of content you need.
- Competitor page quality Open the top three ranking pages. Note their word count, backlink profile, and freshness. If they are strong, your page must match or exceed that.
- Seasonal or location bias Volume estimates may be annual averages. A term like 'Christmas gifts' spikes in November. Location-specific queries need localised data.
