Initial SEO analysis
To start with, you might want to get an overview of the SEO issues on your site. You might want to test your site’s speed, check rankings, see if there are any crawl issues or errors in your robots.txt files.
Here are some of the tools you can use to:
Run complete scans to evaluate your entire siteâ€™s SEO healthÂ The 123-reg Search Engine Optimiser tool lets you run in-depth scans for dozens of SEO factors so you can get a complete overview of your siteâ€™s health. This allows you to spot problems without having to check every page on your site manually and also get SEO recommendations to fix them. Itâ€™ll let you know if you have pages with missing or duplicate titles and descriptions, which keywords to focus on to optimise your site, the backlinks youâ€™re getting and more. This tool is perfect for beginners as it doesnâ€™t require much technical knowledge. You can start with a free report and then choose the package that best suits your needs.
Check site rankingsÂ Â To check your siteâ€™s rankings in search engines I recommend one of the following tools:
- SeoBook’s rank checker (free)
- Authority Labs (free 30-day trial)
- Moz’s rank checkerÂ (free 30-day trial)
- Advanced Web RankingÂ (free 30-day trial)
- SEMRush â€“ Unlike the four tools above, SEMRush allows you to see what keywords a page ranks for, instead of you having to add a list of keywords and seeing how they rank. (With the free version, you can only check ten keywords).
Detect SEO issuesÂ Itâ€™s important to know if your site has any issues, like broken links, missing meta data and more. A free tool like SEO Site Checkup allows you to check all issues with your site so you know what needs fixing.All you need to do is enter your website URL, select which issues youâ€™d like to check (or leave it to default to All factors) and click “Checkup”.
Other tools you can use:
Check the number of pages indexed by GoogleÂ Google Search Console (formerly Webmaster Tools)Â includes various invaluable tools that help you identify issues with your site as well as opportunities to improve its performance and boost website traffic. So, to find out how many of your siteâ€™s page Google has indexed, go to Â Google Index -> Index Status.
If you want to find out what else you can do with Search Console, make sure you read our in-depth beginnerâ€™s guide.Â Bing Webmaster ToolsÂ (BWT)Â is also a valuable resource that provides loads of insightful information about on-site issues and more, and itâ€™s also free. Here’s a good guide on how to add your site to BWT, how it works and what other information you can retrieve from it.
Website crawlingÂ A crawl tool is used to analyse your site’s links and check for issues like missing title tags, 404 not found pages, duplicate content or anything else that might affect your site being properly crawled and indexed by search engines. To find out if your site has any issues, you should run a full crawl. Here are a few tools you might consider using:
- Screaming FrogÂ (free version limited to crawling up to 500 URLs)
- Site CondorÂ (free 30-day trial)
- Moz Crawl TestÂ (paid)
- Xenu’s Link Sleuth (free, without any limits or restrictions)
Generate and validate a sitemapÂ A sitemap is a file where you list all the web pages on your site that you want Google and other search engines to index. Google offers a plethora of free sitemap generators which can generate new sitemaps automatically. If you have a multilingual website, a good tool to create your XML sitemap is HREFLANG. To validate your XML sitemap and ensure it’s error-free before you submit it to Google, you can use a free tool like the XML Sitemap Validator.
Find errors in robots.txt fileÂ Robots.txt are files where you specify web pages that you don’t want search engine spiders to access and index. This Robots.txt Checker analyses the format of a robots.txt file and checks to see if it contains errors. Find out more about robots.txt files and how to create one from this tutorial.And, of course, letâ€™s not forget the robots.txt Tester tool from Google Search ConsoleÂ which checks your robots.txt file and shows you whether it blocks Google web crawlers from specific URLs on your site. Hereâ€™s how to use this tool.
Is your site accessible to both visitors and search engines? Is it loading quickly so your visitors donâ€™t get frustrated and leave? Have you checked all your links to ensure they work properly and arenâ€™t broken?
The following tools will help you to:
Check your siteâ€™s speed Google recommends a page load time of under three seconds, and that loading time will be a ranking factor for mobile websites.Â Also, an Amazon study showed a 1% decrease in sales for every 0.1s decrease in response times. In addition, page speed is linked to better rankings and user engagement. So itâ€™s important to check your siteâ€™s speed and improve it if necessary.Here are a few free tools you can use to check how fast your pages are loading and to get recommendations to reduce page load speed:
Find 404 pagesÂ A 404 page is what users see when they try to reach a page on your site that isnâ€™t found â€“ either because they have clicked on a broken link, mistyped a URL or the page has been moved or deleted. You donâ€™t want to have any 404 not-found pages on your site which is why you need to constantly check for this error and fix it quickly. Google Search ConsoleÂ detects these pages for you and you can find a list with 404 pages on your site in Crawl-> Crawl Errors -> Not Found:Other tools you can use to find broken links on your site:
Analytics tools allow you to see how your visitors are interacting with your website and find detailed information about the number of unique visits, most visited pages, the average time a visitor spends on your page and/or site, and more.
Here are a few tools you can use for this purpose:

By checking your inbound (external sites linking to your site) and outbound (links going out from your site to other sites) links you get to see where most of them come from or which sites youâ€™re linking to, if youâ€™ve experienced a decline in inbound links, if there are any broken links on your site, and more.
