How Each Online SEO Tool Works
1. Data & List Cleaner
Clean your URL or domain lists in one go. Paste your list, and the tool will trim each line to the root domain (e.g. example.com), add https:// if needed, and remove duplicates. You get a clean list you can use for outreach or analysis. No software to install. It runs online in your browser.
- Get root domain only (example.com) so you can spot duplicate sites.
- Add https:// so links work in Excel or Google Sheets.
- Remove duplicates so you know the real size of your list.
2. Bulk URL Opener
Paste a list of URLs and open all of them in new tabs at once. No need to copy and open one by one. Great for checking many pages quickly. There is also a WP Admin option: it adds /wp-admin/ to each domain so you can open WordPress dashboards in bulk. Free online tool, no sign up.
3. Duplicate Backlinks Checker
Paste your backlink URLs (the pages that link to you). The tool finds which domains appear more than once. So you can see who is linking to you from many pages. That helps you spot sitewide links or over optimized links. Simple to use. Runs online in your browser.
4. Bulk Hyperlink Generator
You have URLs and anchor text in two columns. This tool turns them into HTML links in one go. Paste URLs in one box and anchor text in another. You get ready to use HTML you can copy into a page or CMS. Saves time when you need many links at once. Free online.
5. Duplicate Checker
Paste a list of lines (URLs, keywords, or any text). The tool finds duplicate lines and shows how many times each appears. You can see which items are repeated and clean your list. Useful for keywords, URLs, or any list you need to deduplicate. Works online, no install.
6. Google Index Checker
Check if your pages are in Google. Paste a list of URLs. The tool looks up each one with a site search so you see which are indexed. So you know which pages Google has and which it does not. No API key. Free online index checker.
7. Column Combiner
You have two or three columns of words or phrases. This tool combines them into one column with a separator you choose (comma, dash, etc.). One column + second column + third column = one combined row per line. Good for merging keyword lists or building variations. Free online.
8. On Page Audit
Enter a URL. The tool fetches the page and shows you the title tag, meta description, and how many H1 and H2 headers it has. So you can do a quick SEO audit of a page without opening dev tools. Use it to check your own pages or competitors. Simple online on page audit tool.
