SEO tools — what they do and when to use them

Meta tags are HTML elements that search engines and social platforms read before displaying your page in results. A well-written title tag (50–60 characters) with a relevant keyword and a compelling meta description (150–160 characters) can improve click-through rate by 5–20% even without a ranking change — because CTR is a factor in ranking, this creates a compounding effect. The meta tag analyzer audits your title, description, canonical tag, robots directive, Open Graph tags, and Twitter Card tags in one pass, flagging missing or out-of-range values instantly. UTM parameters are query string parameters (utm_source, utm_medium, utm_campaign, utm_content, utm_term) appended to URLs to track which campaigns, channels, and pieces of content drive traffic in Google Analytics 4 or any UTM-aware analytics platform. Without UTM tracking, GA4 lumps all referral traffic into "direct" or misattributes it, making it impossible to calculate true ROI by channel.

Structured data (schema markup) in JSON-LD format tells search engines the semantic meaning of your content — distinguishing a recipe from a review from a job posting. Pages with valid schema markup become eligible for rich results: star ratings, FAQ dropdowns, event cards, and product prices displayed directly in search results, which typically increases CTR significantly above plain blue links. The robots.txt generator creates the file that controls which pages search engine crawlers can access; incorrect rules can accidentally block entire sections of your site from being indexed. Keyword density analysis ensures your target keyword appears naturally in content without over-optimisation — the generally accepted guideline is 1–2% density, with primary keywords appearing in the title, first 100 words, at least one subheading, and the meta description. The sitemap generator produces a valid XML sitemap that you submit to Google Search Console to accelerate discovery of new or updated pages.

An XML sitemap accelerates discovery of new pages. Structured data (schema markup) makes your content eligible for rich results — star ratings, FAQ dropdowns, and event cards directly in search results. UTM parameters let you track exactly which campaigns, channels, and content drive traffic, without guessing in Google Analytics. Meta tag analysis catches common issues — missing descriptions, title length violations, absent canonical tags — that silently hurt indexing and click-through rates. Keyword density analysis helps you write naturally and spot over-optimisation before publishing.
