Your HTML title tag appears in browser tabs, bookmarks and in search result pages.

Make your title tags clear, concise (20-70 characters, 200-569 pixels) and include your most important keywords.

Meta descriptions allow you to influence how your web pages are described and displayed in search results. A good description acts as a potential organic advertisement and encourages the viewer to click through to your site.

Keep it short and to the point; the ideal meta description should contain between 70 and 160 characters - spaces included (600 - 940 pixels).

Ensure that each of your web pages have a unique, straightforward meta description that contains most important keywords. These keywords are especially important because they appear in bold when they match the user’s search query (See the Google Preview below).

Check your Google Search Console (Search Appearance > HTML Improvements) for any warning messages to identify meta descriptions that are too long/short or duplicated across more than one page.

This is a representation of what your Title Tag and Meta Description will look like in Google search results.

Search engines may create their own titles and descriptions if they are missing, poorly written and/or not relevant to the content on the page and cut short if they go over the character limit. So it’s important to be clear, concise and within the suggested character limit.

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.

While it is important to ensure every page has an <H1> tag, only include more than one per page if you're using HTML5. Instead, use multiple <H2> - <H6> tags.

The Keyword Cloud provides an insight into how relevant a topic or keyword is to the content on your page.

It's important to do keyword research to get an understanding of the keywords that your audience is using. There are a number of keyword research tools available online to help you choose which keywords to target.

Alternative text allows you to add a description to an image. Since search engine crawlers cannot see images, they rely on alternative text attributes to determine relevance to a search query. Alternative text also helps makes an image more likely to appear in a Google image search and is used by screen readers to provide context for visually impaired users.

It looks like most or all of your images have alternative text. Check the images on your website to make sure accurate and relevant alternative text is specified for each image on the page. Try to minimize the number of alt text characters to 150 or less (including spaces!) to optimize page load times.

We've discovered 3 pages on usedasa.com.

A low number can indicate that bots are unable to discover your pages, which is commonly caused by bad site architecture & internal linking, or you're unknowingly preventing bots and search engines from crawling & indexing your pages. An unusually high number could be an indication of duplicate content due to URL parameters.

Make sure your website's XML sitemap is present and that you've submitted it to the major search engines. Building backlinks to your website's internal pages will also help bots to discover, crawl and index them, while building authority to help them rank in search results at the same time.

Check Index Status and Crawl Errors in Google Search Console to track the status of your crawled/indexed pages.

If you use parameters in your URL like session IDs or sorting and filtering, use the rel="canonical" tag to tell search engines which version of those pages is the original.

Links pass value from one page to another. This value is called 'link juice'.

A page's link juice is split between all the links on that page so lots of unnecessary links on a page will dilute the value attributed to each link. There's no exact number of links to include on a page but best practice is to keep it under 200.

Using the Nofollow attribute in your links prevents some link juice, but these links are still taken into account when calculating the value that is passed through each link, so using lots of NoFollow links can still dilute PageRank.

Broken links send users to non-existent web pages. They hurt a site's usability and reputation, which impacts SEO.

Fortunately your page doesn't contain any broken links.

Be proactive in checking your pages to make sure they don't have any broken links.

Search engines see www.usedasa.com and usedasa.com as different websites. This means they could see a large amount of duplicate content, which they don't like.

Fortunately your website redirects www.usedasa.com and usedasa.com to the same site.

A robots.txt file allows you to restrict the access of search engine crawlers to prevent them from accessing specific pages or directories. They also point the web crawler to your page’s XML sitemap file.

Your site currently has a robots.txt file. You can use Google Search Console's Robots.txt Tester to submit and test your robots.txt file and to make sure Googlebot isn't crawling any restricted files.

XML sitemaps contain the list of your URLs that are available to index and allow the search engines to read your pages more intelligently. They can also include information like your site’s latest updates, frequency of changes and the importance of URLs.

Be sure to only include the pages you want search engines to crawl, so leave out any that have been blocked in a robots.txt file. Avoid using any URLs that cause redirects or error codes and be sure to be consistent in using your preferred URLs (with or without www.), correct protocols (http vs. https) and trailing slashes. You should also use your robots.txt file to point search engine crawlers to the location of your sitemap.

URL parameters are used to track user behaviors on site (session IDs), traffic sources (referrer IDs) or to give users control over the content on the page (sorting and filtering). The issue with URL parameters is that Google sees each unique parameter value as a new URL hosting the same thing - meaning you could have a duplicate content problem. Sometimes, it’s able to recognize these URLs and group them together. It then algorithmically decides which URL is the best representation of the group and uses it to consolidate ranking signals and display in search results. You can help Google recognize the best URL by using the rel="canonical" tag.

Use the URL Parameters Tool in Google Search Console to tell Google how your URL parameters affect page content and how to to crawl URLs with parameters. Use this tool very carefully - you can easily prevent Google from crawling pages you want indexed through overly restrictive crawling settings, especially if you have URLs with multiple parameters.

Using underscores in your URL makes it hard for search engines to determine your site's relevance to a search. Google sees hyphens as word separators while underscores are ignored. So the search engine sees http://usedasa.com/wp-content/uploads/2013/12/cisco_logo-600x316.jpg as all one word. Use hyphens in your URLs instead: http://usedasa.com/wp-content/uploads/2013/12/cisco-logo-600x316.jpg.

We've detected underscores in your URLs. Change underscores to hyphens to maximize your SEO.

Great, you aren't using Flash or frames on your site.

While it often looks nicer, Flash content can't be properly indexed by search engines. Maximize your SEO efforts by avoiding Flash.

Search engines also have problems with frames because they can't crawl or index the content within them. Avoid them if you can and use a NoFrames tag when you can't.

Your domain is the human-readable address of your website on the Internet. How long your domain name has been registered does have a limited impact on your rankings in search results.

Mobile friendly pages make it easy for users to complete their objectives and common tasks and use a design or template that is consistent across all devices (uses responsive web design).

Google released a new mobile ranking algorithm that expanded the use of mobile-friendliness in its mobile search rankings. With almost half of all Google search queries originating on a mobile device, it is important to make sure your mobile site is optimized for these users.

80% of adult Internet users now have a smartphone. You should definitely be optimizing your website to render on the most popular mobile devices.

Touchscreen readiness is an important aspect of your site’s mobile friendliness. Your tap targets should be at least a 48 pixels in height and width with at least 32 pixels of extra space on all sides. You can further improve your User Interface by adding size and density buckets to accommodate varying device sizes and screen densities.

Great, your website does not embed any special types of web content, such as Flash, Silverlight or Java, so your content can be accessed on all devices.

The text on usedasa.com is too small, impacting your mobile friendliness. To fix this, first make sure your viewport is configured. You can do this using our Mobile Viewport criteria below.

Next, implement the recommendations below:

• Use a base font size of 16 CSS pixels.
• Use sizes relative to the base size to define the typographic scale.
• The general recommendation for spacing between characters is 1.2em.
• Restrict the number of fonts used and the typographic scale.

The viewport is an element of a page’s responsive design. It’s the area of a webpage visible to the user and varies between devices.

It looks like usedasa.com could be missing a meta viewport.

Use the meta viewport tag in the <head> to set the viewport to the device’s screen size. It should look like this: <meta name="viewport" content="width=device-width, initial-scale=1.0">.

Mobile or responsive frameworks are an important part of website optimization as they assist developers in creating applications which are applicable to multiple devices.

Keep your URLs short and clean and avoid long domain names when possible.

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.

Resource: Search for a good domain name. If no good names are available, consider a second hand domain. To prevent brand theft, you might consider trademarking your domain name.

Tips for multilingual websites:

• Define the language of the content in each page's HTML code.
• Specify the language code in the URL as well (e.g., "mywebsite.com/fr/mycontent.html").
• Use hreflang tags to specify language and country for Google, and the "content-language" meta tag to specify the language and country for Bing.

The Doctype is used to instruct web browsers about the document type being used. For example, what version of HTML the page is written in.

Declaring a doctype helps web browsers to render content correctly.

Specifying language/character encoding can prevent problems with the rendering of special characters.

Using an SSL certificate creates an encrypted connection between your visitor's browser and your website's server adding an extra layer of security. In 2014, Google announced that HTTPS would become part of their ranking algorithm and since your website is not HTTPS, it will likely rank below your HTTPS competitors. When moving to HTTPS, follow these best practices for a smooth transition:

• Use a serious issuer to purchase your SSL certificate
• Redirect all of your HTTP pages to the HTTPS version of your website
• Use HTTP Strict Transport Security in your headers
• Renew your SSL certificate every year, before it expires
• Make sure that all of your content (CSS, etc.) is linked to HTTPS
• Update your XML sitemap to ensure the URLs include HTTPS and update the robots.txt file to reference this version
• Register the HTTPS website in Google & Bing Search Console/Webmaster Tools
