  • http://cdn.sigmatex.nl/media/catalog/category/Aanbiedingen_1.jpg
The "alt" attribute provides a text equivalent for the image. If the browser cannot display an image the alt description will be given in its place. Furthermore, some visitors cannot see images as they might be blind in which the alt tag provides a valuable image description. Finally, search engines utilize the alt attribute for image search indexing. (www.w3.org/QA/Tips/altAttribute)


We have found following title:

"Serverkast kopen? Patchkast of wandkast? Sigmatex.nl serverkast leverancier."

Length: 76 characters
The <TITLE> element provides a short piece of text describing the document. The title is very important as it shows in the window title bars, bookmarks and search results. Title should be between 60 to 80 characters long. (www.w3.org/QA/Tips/good-titles)

Description Metatag

We have found following description:

"Serverkast Kopen? Bestel patchkast, wandkast, serverrack,19 inch rack, server rack of server kast bij sigmatex.nl. Sigmatex.nl serverkast leverancier."

Length: 150 characters
The description attribute should provide a concise explanation of a Web page's content. Also, the description is often displayed on search engine results and can indirectly affect page ranking.

Keywords Metatag

We have found 10 keywords:
  • serverkast
  • patchkast
  • wandkast
  • serverrack
  • 19 inch rack
  • server rack
  • server kast
  • serverrack
  • sigmatex
  • 18u
    Length: 109 characters
    The keywords attribute was utilized by search engines to provide more accurate search results. Due to the over usage and spamming the keywords attribute has been phased out and is no longer relevant. Google doesn't use the "keywords" meta tag in web search ranking.

    Text to HTML Ratio

    The Text to HTML ratio is 20.47%
    Original content is by far the single most important element to search engines. Low Text to HTML ratio indicates little content for search engines to index. We consider it to be good practice to have a Text to HTML ratio of at least 10% and ideal above 20%

    Keyword Density & Consistency

    Consistent Keywords % Density # Count T Title D Desc. H <H> A ALT B <b>

    Keywords density and consistency are notable factors for optimal page SEO. Preferred keywords should have higher keywords density indicating their importance. Optimally, preferred keywords should also be consistently utilized in multiple essential areas of the page such as title, description meta tag, h1 through h6 headings, alt image attributes, backlinks and internal links anchor text. Keyword density of above 6% can indicate that the word or a phrase appears too many time in the content.


    No frames detected.
    It is not recommended to use frames or iframes because they can cause problems for search engines. It is best to avoid frames and inline frames whenever possible (searchenginewatch.com/article/2064573/Search-Engines-and-Frames). If frames must be utilized consider <noframes> tag. (www.w3schools.com/tags/tag_noframes.asp).


    No flash detected.
    Flash and other reach-media technologies should primarily be utilized for decorative purposes. This makes your site more search engine friendly and improves accessibility (support.google.com/webmasters/bin/answer.py?hl=en&answer=72746#1).

    Page Rank

    PR: 4 out of 10 (Above Average)
    PageRank is Google's measure of the importance of a page. It is based on complex algorithmes evaluating page content, authority, keyword density, back links, traffic, demand and more.

    Indexed Pages

    Estimated number of pages indexed by Google™: 2,590
    Estimated number of pages indexed by Bing™: 3
    The higher number of indexed pages the more content search engines can index, which increases overall value of the website.

    Domain Age

    Data could not be obtained.
    Age of the domain is one of the many signals that search engines utilize for ranking. Brand new domains generally have more difficult time to rank high for the first few months. (http://www.coconutheadphones.com/does-domain-agematter)

    Domain Expiration

    Data could not be obtained.
    Domain expiration far in to the future is considered a good practice as it promotes confidence in your website, decreases chances of losing domain and in certain cases might help with search engine ranking. (https://www.hover.com/blog/three-reasons-to-renew-your-domain-names-for-five-years/)
