Let’s start with on-site SEO. Screaming Frog SEO Spider allows you to check if your page titles (it is a title tag that appears in the top of a browser window) are over 65 characters long, whether you have duplicates, and if you have multiple page titles. Next, it shows you how many duplicate meta descriptions you have and how long they are so that you can make changes if required. It will also check the same features for your h1 and h2 tags. The great thing about the tool is that it helps you to generate an XML sitemap for your website. The XML sitemap is a document that enables Google crawlers to understand how many links are there on your site. For WordPress blogs, you can also create XML sitemap by using Yoast SEO Plugin.
If your images are too big, they may slow down the loading time of your website. Slow sites do not rank high in Google. Screaming Frog shows you which images need to be resized. Resizing images in the dashboard to desired dimensions will not help at all. Their actual size is still big. They will be loaded with their exact size first and then will get scaled by the browser to dimensions you set in the dashboard (if you are using WordPress or other CMS system). All images should also have an alt tag. The alt tag is important for search engines because it helps them to understand what an image displays.
Broken links and Canonicals
A broken link is when a link on a web page does not work. It may be due to incorrect URL or because the destination page does no longer exist. Screaming Frog SEO Spider allows you to check for broken links on your website. You can also generate reports in CSV file format so that you can work in Excel if it is better for you. Canonical URL tells search engines that particular URL is the original one. It is very helpful when you have several pages with the same content (good for e-commerce websites with multiple pages displaying certain product category in different colors, for example). You set canonical URL for the subpage of your choice, and you point other subpages (with the same content) to that one. It allows avoiding the duplicate content issue. Screaming Frog SEO Spider checks your website for any errors regarding your canonical links.
Screaming Frog SEO Spider is a great tool for on-site SEO. It will crawl your website and will show you where you can introduce changes. You can filter data by categories such as duplicates, character limit, missing descriptions and more. The tool will check your meta descriptions, h1 and h2 tags, meta keywords, page titles, internal and external links and more. You have an option to open listed links in a browser as well as export reports on individual data (canonicals, error codes, images missing alt tags, internal and external links and other). You can use the tool to create an XML sitemap. It will help search engines understand better how your site works. You then need to upload your sitemap to Google Search Console. There is also an option to integrate Screaming Frog SEO Spider with your Google Analytics Account. All in all, it is a perfect tool for either competitor analysis, your website improvement or both.
