The first tool you should
consult is the
HTML5 Validator.nu -
This is a great tool. It is totally free.
You don't have to register or provide an
email address to use it. It does not have one
of those annoying captcha things that asks you
to input a string of letters and numbers that
no human being can read.
Know Your Audience ... and always
keep them in mind. After all, every
thing you are doing, you are doing for them.
While you are validating your
markup, it is a good time to think
about search engine optimization
(SEO). Take a quick look at this
most simplified but true example.
The "Perfectly" Optimized Page
If you will follow the simplistic
approach outlined here, it will pay
big dividends for your webpage.
Of course the W3C people have a
validation service here that you can
test against as well.
Nu Markup Validation Service
If you are transitioning to HTML5,
you should take the little extra
time to include some microdata on
your pages. A good resource page to
help you out may be found at
Use the schema.org reference to
create data that will be read by
Google, Bing and Yahoo.
Google has a testing tool here that
will verify your markup
also has a testing tool in their
. I have gotten
different results with microdata
code comparing the results with
these two tools. In particular,
Google would verify more of the code
than Bing and took a few tries at
manipulating the code and testing to
get thee same results from both.
If you are using Wordpress, there is a
plugin that will automatically do the
microdata markup for you. I use it on
the news blog portion of our website.
Just search for Opengraph and Microdata
Generator. Speaking of Opengraph, that is
the code pushed by Facebook. The last two
versions of this site included a lot of it
in the headers. With this rework I opted to
drop it from every page and only include it
on a few selective pages. Why? Fewer than a
dozen Facebook shares.
The Big Compromise - Fancy frills
or speed? Some of both please.
Tools That Test Page Speed
Although the primary purpose of the
following three tools is to test
your page for speed, they all will
provide insight into much more
details of your page.
Google's PageSpeed Insights
PageSpeed Insights analyzes the content
of a web page
, then generates suggestions
to make that page faster.
Run a free website speed test
multiple locations around the globe
using real browsers (IE and Chrome)
and at real consumer connection speeds.
You can run simple tests or perform
advanced testing including multi-step
transactions, video capture, content
blocking and much more. Your results
will provide rich diagnostic information
including resource loading waterfall charts,
Page Speed optimization checks and
suggestions for improvements.
Testing Tip That May
Not Be So Obvious
Most people will test their home page to the
exclusion of all other pages. Some
"so called" SEO Experts will stress
the load-time of your home page
because they say it is the initial
page that most people visit.
Actually, most of our visitors hit
other pages of our site as the
landing page first. Only fifteen
percent or less of our first time visitors view
our home page first. Return visitors have it cached.
Visitors that view our home page after first
viewing another page, have the benefit of a

Those files require the jquery library in
order to work. I reference that library at
Google instead of this server. Why? Because
there is a good chance that your browser already
has the Google instance of the file cached.

I hope you find these tools as
helpful as I have. Improving the web
one website at a time is a great
thing for everyone. Maintaining a
website is a never-ending
proposition. This is the seventh
iteration of our site since it was
launched many years ago. I'm very
excited about HTML5 and the things
it brings to the table.
Check your robots.txt file here
Having a correctly formatted
robots.txt file is crucial.
After you have tested your html and server,
take a look at other resources to
