Hi,

I am currently building an online application using PHP, where I need to calculate the text to html ratio of a website.

Anyone has a good PHP class or script to calculate this?

Thanks!

    I see a few examples of use after doing a search. I don't see code examples though.

    I did find
    javascript:alert('text/html = '+(b=document.body).innerText.length/b.innerHTML.length);void(0);

    in a comment at Search Engine Optimization: Textarea and HTML comments - CodingForums.com

    Unfortunately I'm not proficient in Javascript :/

    I don't want to cut the possibility of doing Javascript - but I need a better tutorial in order to implement it ...

    Anyone with a better solution?

      What exactly do you mean by "text to HTML ratio"?

        The ratio of the number of text characters that the browser actually displays to the total number of characters in the HTML doc. Essentially, the number of characters between the closing tag symbol > and the opening tag symbol.

          And why would you want to know this?

          Any way load the page into a string and save its size.
          Then use the strip_tags function to remove the html and then check its size.
          Compare as you see fit.

          Gotcha. I guess a better question then would be why would anyone ever need to know this?

    I am currently building a tool to analyse this as it is an important factor for SEO.

    jassmee, I am not looking for the actual size in pixels - I need the ratio of html characters to content characters.

    KirkMcD is the one who got the closest ... thought there might be something ready for use out there though!

    You can try something below, if your real intention is to find out keyword density.

    $content = strip_tags($html_content);
    $len = strlen($content);

    foreach($keyword_array as $keyword)
    {
    $found = substr_count($content, $keyword);
    $keyword_density[$keyword] = ($found / $content);
    }

    Well, I really don't think keyword density is really important now, since Google just changed its SEO algo again.

    I was searching for Content/HTML ratio - followed KirkMcD's suggestion and it worked.

    Yeps, keyword density is next - traderookie's code gave errors. Will see how to go about it.

    I am sure both factors still affect Google's algorithm.
