Enter Your Seed Keyword
Type your main topic or keyword into Trendly. Choose your target country and time range. Start with the past 12 months for a reliable interest trend baseline.
Analyse the Trend Line
Look for keywords with steady or rising interest over time. Avoid keywords with declining or highly seasonal trends unless your content strategy accounts for seasonality.

Trendly shows you rising and top related queries from Google. These are gold — they reveal new keyword angles your competitors may not be targeting yet.
Collect Autocomplete Suggestions
Use the Google autocomplete suggestions section in Trendly to find long-tail keyword variations. These longer phrases often have lower competition and higher conversion intent.
Check Competitor DR Scores
Use our free Domain Rating Checker to see how authoritative the sites ranking for your target keyword are. If top results have DR 70+, you will need significant backlinks to compete.
Write and Optimise Your Content
Use your keyword research to write thorough, authoritative content. Include your target keyword in the title, H1, first 100 words, meta description, and image alt text for best results.
What is Ahrefs Domain Rating — Our Free SEO Tool Explained
Our free SEO tool for domain authority checking uses Ahrefs Domain Rating (DR) — a metric that measures the strength of a website's backlink profile on a logarithmic scale from 0 to 100. Created by Ahrefs, one of the world's leading SEO platforms, DR is the industry-standard measure of website authority used by SEO professionals, digital marketers, and content creators worldwide. A higher DR score generally indicates a stronger, more authoritative website. While DR is not an official Google ranking factor, extensive research consistently shows that higher DR correlates strongly with better search engine rankings. Use our free Domain Rating Checker to check any website instantly.
Just getting started. Focus on creating great content and building first backlinks.
Growing site. Target long-tail keywords and build links from directories and niche sites.
Established site. Can compete for moderately competitive keywords. Guest posts help here.
Strong site. Competitive for most keywords. Editorial backlinks from major publications.
Elite sites — major news publishers, universities, government sites. Extremely hard to reach.
DR is particularly useful when using our free SEO tools to evaluate link-building opportunities. When a high-DR site links to yours, it passes significantly more link equity than a low-DR site. Use our free Domain Rating Checker to vet guest post and backlink prospects before reaching out. According to Moz's backlink research, pages with more high-quality backlinks consistently outrank those without. For a complete backlink profile including referring domains, URL Rating and anchor text breakdown, the full Ahrefs platform offers comprehensive paid tools starting at $99/month. Our free SEO tool gives you the essential DR score at zero cost.
