Great, your website directs www.three.co.uk and three.co.uk to the same URL.

Redirecting requests from a non-preferred domain is important because search engines consider URLs with and without "www" as two different websites.

Great! You have clean (user-friendly) URLs which do not contain query strings.
Clean URLs are not only SEO-friendly but are also important for usability.

Good, your website's IP address is forwarding to your website's domain name.

To check this for your website, enter your IP address in the browser and see if your site loads with the IP address. Ideally, the IP should redirect to your website's URL or to a page from your website hosting provider.

If it does not redirect, you should do an htaccess 301 redirect to make sure the IP does not get indexed.

Great, your website has a robots.txt file.

A robots.txt file allows you to restrict the access of search engine robots that crawl the web and it can prevent these robots from accessing specific directories and pages. It also specifies where the XML sitemap file is located.

Click here to check your robots.txt file for syntax errors.

Your website does not have an XML sitemap - this can be problematic.

A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.

We recommend that you generate an XML sitemap for your website and submit it to both Google™ Webmaster Tools and Bing Webmaster Tools. It is also good practice to specify your sitemap's location in your robots.txt file.

Great, your title contains between 10 and 70 characters.

Make sure your title is explicit and contains your most important keywords.

Be sure that each page has a unique title.

Great, your meta description contains between 70 and 160 characters (spaces included).

Meta descriptions allow you to influence how your web pages are described and displayed in search results.

Ensure that your meta description is explicit and contains your most important keywords.

Check your Google™ Webmaster Tools for any warning messages on duplicate meta descriptions.

Great, your website is structured using HTML headings (<H1> to <H6>).

Use your keywords in the headings and make sure the first level (<H1>) includes your most important keywords. Never duplicate your title tag content in your header tag.

For more ‪‬effective SEO, use only one <H1> tag per page.

Alternative text (the alt attribute) is missing for several images. Add alternative text so that search engines can better understand the content of your images.

Remember that search engine crawlers cannot actually "see" images, so the alternative text attribute allows you to assign a specific description to each image.

Alternative text describes your images so they can appear in Google™ Images search results.

Check the images on your website and make sure ‪‬‬effective alternative text is specified for each image.

Restrict the number of characters in alt text to 150, including spaces, and minimize the size of images to optimize your website's page load times.

This page's ratio of text to HTML code is below 15 percent, this means that your website probably needs more text content.

A ratio between 25 and 70 percent is ideal. When it goes beyond that, the page might run the risk of being considered spam.

As long as the ‪‬‬content is relevant and gives essential information, it is a plus to have more of it.

Flash content has been detected on this page.

Flash should only be used for specific enhancements. Although Flash content often looks nicer, it cannot be properly indexed by search engines. Avoid full Flash websites to maximize SEO.

This advice also applies to AJAX.

Nevertheless, here are some quick SEO tips for websites using Flash.

Great, there are no frames detected on this page.

Frames can cause problems on your web page because search engines will not crawl or index the content within them.

The more pages that search engines index, the better, as this offers more opportunity for your website to be found.

A low number (relative to the total number of pages/URLs on your website) probably indicates that your internal link architecture needs improvement and is preventing search engines from crawling all of the pages on your website.

Check Google™ Webmaster Tools under Health and Index Status, to keep track of the status of your site's indexed pages.

A descriptive URL is better recognized by search engines. A user should be able to look at the address bar and make an accurate guess about the content of the page before reaching it (e.g., http://www.mysite.com/en/products).

Keep in mind that URLs are also an important part of a comprehensive SEO strategy. Use clean URLs to make your site more "crawlable" by Google™.
