On-Page SEO Checklist 2015

The on-page SEO checklist has been specifically designed for our new SEO scan tool. With this tool you can check the SEO score for your website and make improvements where needed based on the advice that the tool generates.
The tool focuses primarily on the layout and structure of your website. Points are included for the following: Content analysis, Meta tags, link extractor, and loading speed.

Meta Tags

  • Title
    Optimum title of your page should contain between 10 and 70 characters (without spaces). The most important keywords should be placed in the front of your title.
  • Description
    An optimal description of your web page should contain between 70 and 160 characters and just like the title, the important keywords should appear in the front.
  • Keywords
    The use of Meta tag keywords are not used by Google but it is important to use keywords as other search engines may make use of them. Try to use between 5 and 8 keywords and place the most important ones in the front.
  • OG Meta
    Open Graphic Meta is intended to give social media links more value. With these tags you can decide which title, description, and picture are placed. For example Facebook, Linkedin, and Twitter. For more information, see the Open Graphic Protocol.
  • Dublin Core
    With Dublin Core Meta tags you give extra information to a web page. For more info on this see: Dublin Core.
  • Language Website
    Language Meta tags make clear what language your website uses.


  • Headings
    The H1, H2, and H3 tags are important to indicate what the website is about. The H1 tag can only be used once on your website and should contain your primary keywords. You should also place relevant keywords in your H2 and H3 tags. This will ensure that the website is also found for broader terms.
  • Pictures
    You should always provide keywords in your images alt tags and title attributes. Be sure to use your most important keywords so that the search engines can read your images.
  • Text/HTML Ratio
    Make sure there is a content to HTML ratio of between 25% and 70% on your webpage.
  • Flash
    Flash objects cannot be read by search engines so try to avoid using Flash wherever possible.
  • Iframes
    Iframes cannot be read by search engines, try to avoid them. Alternatively you can use JavaScript or PHP on your website.

Link Structures


  • Use friendly URLs and leave the keywords visible. Google looks first for the keywords in your URL. Try to avoid using underscores in your permalinks.
  • In-page Links
    Try linking to at least 5 relevant web pages within your site. Enter a “rel=nofollow” attribute along with links to a file or PDF.

Keyword Ratio

As mentioned above, it is important that your keywords appear in your URL, Meta tags, and image descriptions. The SEO Scan tool checks the density of the keywords and displays it.

  • URL
    Provide a clear and short URL. Try to explain what the website is about in preferably 1 to 2 words.
  • Favicon
    A Favicon is a small icon to the left of what your browser is for your URL. This also provides a convenient image for visitors that want to bookmark your site.
  • Print Friendly CSS
    Make sure you print CSS-friendly for the search engines by entering a “media=print” attribute in the CSS link.
    Document Formatting
  • Doctype
    Specify the type of documents your webpage has.
  • Encoding
    Please specify the type of encoding your document contains, it is usually UTF-8.
  • W3C Validity
    Check your website for W3C errors and try to improve it. See more info: W3C Validity
  • Web Speed

    The speed of your website has become very important to your search engine ranking according to Google. Try not to use too much Java on your site and avoid HTML tables if at all possible.
