      bobjonkman favorited something by blacksam: For me, the most interesting piece of future human technology in The Expanse is the ubiquitous “recycler”. It’s a mysterious contraption that you can throw basically anything into (food, utensils, clothing, guns) and it presumably “recycles” them. It works so efficiently that nobody seems to bother to clean or re-use […]

    • New note by bobjonkman 19 September 2021
      Reminds me of a riddle I heard in high school (around the time Canada switched to metric): If it's 0 Celsius here, and twice as cold in Ottawa, what's the temperature there? Conflating both the #ZeroIsNotMinimum problem and a negatively worded question about positive values. Think of "If it's 273 Kelvin here, and twice as […]

      bobjonkman favorited something by lxo: both C and F lead to such nonsense as "temperature has doubled/halved in just a few hours" if it did, we'd be in deeper trouble. but that's how misleading temperature scales get with a zero that isn't really zero imagine if we used height or weight units whose fake-zero was […]

Invalid HTML considered harmful

Posted by Bob Jonkman on 28th April 2009

Screenshop of HTML Dog Web SiteValid HTML is not just useful for browsers. One of the big benefits of having valid HTML is that search engines can properly index your site. If the HTML is invalid, then the search engines may index you incorrectly, or not at all. Google isn’t the only search engine out there, and you want to drive as much traffic to your site as possible.

There appears to be some contention whether valid HTML makes a difference to search engines or not. Some say it doesn’t; or that it depends on the search engine; others have evidence it matters a lot.

Even if you’re not coding by hand, I urge you to have a look at HTML Dog, a set of tutorials on creating valid HTML. When things don’t work as expected you can turn here for examples in XHTML.

If you’re going to be using an editor for your Web pages, pick an editor that creates proper HTML code. Abandon FrontPage. I suggest using KompoZer, which is based on the same rendering engine as Firefox (Gecko).

You should also be checking your pages in Opera, which is a browser that is even better for standards-compliance than FireFox. The Chief Technology Officer for Opera is the same guy that wrote the Cascading Style Sheets specification, so it has a good pedigree.

If you’re using Firefox then be sure to check your pages with the HTML Validator addon:

Favicon - Skynet.behttp://users.skynet.be/mgueury/mozilla/

Screenshot - HTML ValidatorAnd when you think your site is done, check each page with the full-strength validator:

Favicon - W3C HTML Validatorhttp://validator.w3.org/

Favicon - CSS Validation Servicehttp://jigsaw.w3.org/css-validator/
