HTML 5 SEO Good Pratices

Posted: May 30, 2012 in Anouncements

In HTML 5 Universe when we talk about Good Pratices we always associate to the struture of our markup to be strict or to the excellent template initiative of Boilerpart (http://html5boilerplate.com/) .

But their are other good Pratices to think about when developing for the WEB…One of the things few people talk about is SEO, let’s take a look in to some good pratices for the HTML 5 and is friend SEO.

SEO & HTML 5

First of all HTML 5 per sí, is not a solution for every SEO problems and quests. From a usability perspective HTML 5 have the quality to maximize user’s experience without extra plugin’s. This is really good foremost searchbot’s since they could arawl and index our site even if we have a ritch experience (this was a gap in the RIA web app’s based on flash Silverlight and other’s).

Other good notice that HTML 5 brings to SEO are their new Tag’s, let’s take a look at some of them:

  • <article> specifies an independent block of content. The contents of an article tags should be entire self-contained. A blog post or new article could be wrapped in an <article> tag, for example.
  • <section> specifies a subsection of a block of content, such as an <article>. If a blog post was broken into several sections by subheaders, each section could be wrapped with a <section> tag. Just as books have chapters, blocks of content can have section.
  • <header> could server two purposes: (1) to specify the header of a page or (2) to indicate the header section of a self-contained block of content (an <article>). <header> tags might contain navigation, branding or the document headline.
  • <hgroup> is used to wrap a section of headings (<h1> through <h6>). A great example would be an article with both a headline and subheadline at the top:
  • <footer> is a bit like the <header> tag. It could specific the <footer> of an entire HTML document or the footer of an <article>. This may contain things like footer navigation or meta-data about an article (author, data, etc)
  • <nav> is mean to enclose site navigation. This can be used anywhere: main site navigation, previous/next article links, or pagination.
  • <aside> is for content related to the parent element in which is resides, but not strictly part of the main document. In other words,could be used on a website sidebar or it could be used within an <article> for special call outs – like the “did you know” call outs found in many books.
  • <video> is for video content. Its purpose is to provide a cross-browser compatible way to display video.

But this is just one vector of SEO in HTML 5, the other vector is maintain all the good practices you already had in the past.

i will give some off the topic’s i consider as the most important pratices to have at a SEO level that are equal true to HTML 5 as it was in the past.

Use Title Tags

The <title> tag make a web page more meaningful and search-engine friendly. In HTMl 5 consider how this relates with the different outlines you have in a page

Use Descriptive Meta Tags

Meta tags make your web page more meaningful for user agents like search engine spiders.

<meta name="description" content="This blog talks about Technology and how to understand it and live with her" />

The keywords meta attribute contains a comma-separated list of key words and phrases that relate to your web page. These keywords make your web page even more meaningful.

<meta name="keywords" content="type here your important and meanfull keywords" />

attention don’t spam your descriptions and keyword’s.

Minify, Unify and Move Down JavaScript

This is one off the most important rules that many people often forget.

Use Heading Elements in a smart way

Don’t forget that heading have also a related semantic in the outline where they live, so don’t forget to take that in consideration when choosing your headings.

 

Hope this posts help to ignite your SEO and kill some off the half trues around about HTML 5 and is relation with SEO.

I was invited as a speaker to talk about Offline Webapplication at the private talks of Open software development teams.

Is funny to get back to their stage to talk about Web technologies…In the past they were one of my first class client’s when i was a freelancer core developer.

Thanks for the invite, will be a pleasure to get back, this time to speak about technology in a house where technology and sotware was always viewed as something free and important to make things go futher.

 

Today i had a great talk with some wordpress developer’s who had a good site of e-commerce, and had seem that rentable site hacked…and all their valuable business ruined…

After that was impossible for me to stop thinking about the subject…And after a big trip of subway i remember some couple of things that answer why so many wordpress sites are hacked.

Sometimes technology create us a fake feeling that everything is easy and we don’t need to think out of the box…Great tools of advertisement and social are like that, but with great power comes great responsibility like spiderman said 😉 .

In this post i will present to you some good security prtaices about WordPress CMS, do your own checklist and when you have an installed wordpress server never forget to check this.

  • When manual installing the WordPress plataform in the wp-config.php file (in the installation named wp-config-sample.php), find the section that deal with the secret keys.  these keys will be added only once…remember this keys will  be the secret to hack your site. Use the link https://api.wordpress.org/secret-key/1.1 if you want to generate complex passwords. Put that passwords in the wp-config file.
  • Keep your WordPress up to date, is true that this makes you keep working, but enable you also to cover the bugs correction and security walls on.
  • Keep all your secret keys in the wp-config.php file.
  • Hide your WordPress version, this can give some valuable clues to your web presence enemies. Check the file header.php, and if the code “php add_action(‘wp_head’,’wp_generator’)” is there  remove it. This code line outputs the version of WordPress. This represents an additional risk to your site.
  • admin user is comfortable but not a good username. The first thing you should do after installing wordpress should be to create a new user with administration privileges and delete the admin user. This way you hide the administrator, by default the administrator of a wordpress backoffice is admin and every one know that.
  • The My SQL user you create to deal with wordpress should not have to have full writing capabilities in the database engine.
  • Keep your My SQL backups up to date.
  • Your MYSQL users should be aimed with strong passwords.
  • Grant that in every folder of your solution, you have a empty index.php file.
  • Force SSL encryption when logging to the WordPress admin dashboard, do that by adding to the wp-config.php file the following code: define(‘Force_SSL_ADMIN’,true); for this you need to grant also that SSL is supported by your Web Server HOST.
  • Don´t allow the directories of your wordpress core to be avaible for browsing, this is done at your webserver level (apache, internet explorer…).
  • WordPress administration files reside in wp-admin directoryuse .htaccess to restrict access and allow only specific IP address to this directory and file. If you have static IP address and you always blog from your computer, this can be an option. This is done in the .htaccess file in wp-admin with the following code:
    Order Deny,Allow
    Allow from ww.xx.yy.zz
    Deny from all
  • Restrict file access to the contents folder (wp-content directory) this is done on the  .htaccess file with the following instructions
    Order Allow,Deny
    Deny from all
    <files  ?\.(jpg|gif|png|js|css)$? ~>
    	Allow from all
    </files>
  • There are also some plugin’s who can help you to add an extra layer of security agains sql injection and other atacks i use normally this http://wordpress.org/extend/plugins/bulletproof-security/And that’s all for now, with this simple tricks you can add a lot of extra layers of security to your WordPress website and if your site is your life i would strong recommend you to do this. Hope this post can be helpfull.
