# Website Launch Final Review > Pre-launch website checklist for broken links, mobile responsiveness, SEO tags, and performance. **Category:** Checklist **Keywords:** checklist, website, launch, seo, web development, go live, qa **URL:** https://complete.tools/website-launch-final-review-checklist ## How it works The tool evaluates website inputs using predefined criteria for each checklist item. For broken links, it utilizes HTTP status codes to identify links that return errors such as 404 or 500. Mobile responsiveness is assessed by determining if the website adapts to various screen sizes using CSS media queries. SEO tags are verified by checking for the presence and correctness of title tags, meta descriptions, and header tags, ensuring they comply with search engine guidelines. Performance is measured using metrics like page load time, which is calculated by tracking the time from request initiation to full rendering of the page. These evaluations produce a checklist of issues that need addressing before launch. ## Who should use this Web developers reviewing a site before client handoff. SEO specialists ensuring a site is optimized for search engines. Digital marketers preparing a landing page for a promotional campaign. Quality assurance testers verifying site functionality across different devices. ## Worked examples Example 1: A web developer checks for broken links on a new e-commerce site. Using a link checker tool, they find 5 out of 200 links are broken, leading to 404 errors. They replace these links with correct URLs, ensuring a 97.5% link success rate. Example 2: An SEO specialist evaluates the homepage for SEO tags. They find that the title tag is 60 characters long, which is optimal for Google, while the meta description is 150 characters, also within the recommended length. They suggest modifications to header tags to include targeted keywords, improving potential search rankings. Example 3: A digital marketer assesses performance metrics using Google PageSpeed Insights. The homepage loads in 2.5 seconds, but they identify that optimizing images could reduce load time by up to 1 second. After image compression, the load time improves to 1.5 seconds, enhancing user experience and reducing bounce rates. ## Limitations The tool primarily checks for common issues and may not identify complex site-specific problems such as JavaScript errors or server-side issues. It assumes that all external links are reliable, which may not always be the case. The mobile responsiveness check relies on CSS media queries but may miss issues with JavaScript-driven layouts. Performance assessments may not account for variations in user internet speeds or server loads, which can affect real-world load times. Additionally, the tool does not analyze content quality or user engagement metrics. ## FAQs **Q:** How does the tool identify broken links? **A:** The tool utilizes HTTP status codes to check the response of each link, identifying those that return errors like 404 (Not Found) and 500 (Server Error). **Q:** What criteria does the tool use to evaluate mobile responsiveness? **A:** The tool checks whether the website's layout adapts seamlessly to different screen sizes through CSS media queries and viewport meta tags. **Q:** How are SEO tags validated in the checklist? **A:** SEO tags are validated by ensuring the presence, length, and relevance of title tags, meta descriptions, and header tags, in accordance with best practices for search engine optimization. **Q:** What performance metrics does the tool analyze? **A:** The tool analyzes metrics such as page load time, server response time, and the number of requests made during the loading process to evaluate overall site performance. --- *Generated from [complete.tools/website-launch-final-review-checklist](https://complete.tools/website-launch-final-review-checklist)*
