How to choose the right tool

Start with the problem you are trying to solve:

• Your pages do not get clicked in Google. Use the SERP Snippet Preview and the Meta Title & Description Checker to write titles and descriptions that fit and stand out.
• Pages are missing from Google, or you changed your website. Use the Robots.txt Generator to check crawler rules and the Redirect Checker to make sure old URLs lead to the right new pages.
• You want search engines and AI tools to understand your business. Use the Schema Markup Generator, the Local Business Schema Generator and the llms.txt Generator.
• You are writing or improving content. Use the Word Counter to check length, readability and keyword use.
• You need more reviews. Use the Google Review Link Generator to give customers a one-tap review link.
• You want to know which marketing works. Use the UTM Builder to track campaigns and the SEO ROI Calculator to estimate the value of organic traffic.
• Your website is slow. Use the Image Compressor & WebP Converter to shrink images without uploading them anywhere.

Built for real businesses

These tools were built by the SEMRS team for the same jobs we do for clients every day. They focus on the checks that make a real difference for small and growing businesses in the US, UK, Canada and Australia, rather than vanity metrics. Every tool page includes a short guide with a worked example, best practices, common mistakes and answers to frequent questions, so you understand the result as well as get it.

Private by design

Most of the tools run entirely in your browser. Text you paste, images you compress and campaign links you build are processed on your own device and are not uploaded. The Redirect Checker is the exception, because it has to request the URL you enter; it only checks public websites and keeps results briefly to stay fast for everyone.

When to bring in help

Free tools are perfect for checking and fixing individual pages. When you need a plan for the whole website, ongoing content or help turning traffic into enquiries, our team can take it from there, with prices published openly and a person approving every change before it goes live.
