  • JQuery for easier JavaScript

  • XML

Search engines

Search Engines

  • Search Engines operate by identifying pages that have search terms that match someone’s interests

  • KEYWORDS are these search terms.

  • KEYWORDS are one word or a group of words

  • Search Engines consider a few things including:

    • Your page CONTENT (the HTML)

    • Other people’s links to your page (A tags)

    • Keywords

  • Search Engines offer two types of traffic:

    • Organic (based on indexed content) = free

    • PPC (pay per click) = not free


Meta tags

Meta Tags

  • Meta Tags apply “behind the scenes” descriptors to your pages (not the site…the page!)

  • These exist in the HEAD tags of your HTML document and are NOT seen by the users.

  • Each META tag requires a NAME attribute and a CONTENT attribute.

    <meta name="description" content="Description you write." />

    <meta name="keywords" content="keyword, another keyword, yet another keyword, descriptive keyword" />

    <meta name="robots" content="noindex, nofollow, noarchive" />


Seo tips

SEO Tips

  • The CONTENT (actual words seen by users) should include your KEYWORDS used.

  • The predefined TAGS in HTML should be used to put emphasis where needed

    • Heading tags (H1, H2, H3, etc.), STRONG, EM, etc.

  • If possible, your DOMAIN NAME (whatever.com) should contain a keyword you’d like to have

  • Your file names and folder names should use keywords as well (use hyphens to separate)

SEO Tips

  • Search Engines ONLY see TEXT

    • No Images, Flash Animations, Movies, etc.

    • You can see how it looks by using a text browser (you can use the Google cache)

  • When someone links to your pages, request that the CLICKABLE TEXT should use your keywords

  • They CAN see hidden text with CSS of display: none;

  • GOOGLE Analytics can help you analyze your keywords and site traffic.


Specialized stylesheets

Specialized StyleSheets

  • By default, a stylesheet that is linked in the HEAD of an HTML document is used for ALL devices.

  • We can change this with the MEDIA attribute of the LINK tag.

    <link rel="stylesheet" type="text/css"href="site.css" media="screen"/>

    <link rel="stylesheet" type="text/css" href="site.css" media="print" />

    <link rel="stylesheet" type="text/css" href="site.css" media="handheld" />


Jquery

JQuery

  • JQuery is a FRAMEWORK built on JavaScript.

  • Basically that means another language developed based on an existing language.

  • If you include the JQuery JavaScript file then you can use the JQuery Framework.

  • JQuery is available on Google Code:

    <script type="text/javascript"src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>


Jquery basics

JQuery Basics

  • JQuery has a HUGE site that describes the framework and what you can do with it.

  • With a intermediate understanding of JavaScript and programming, you can probably use JQuery.

  • Some Basics:

    • You select by using the dollar symbol and the CSS selector you’re interested in quotes: $('#sidebar')

    • Then use the DOT operator to perform an action:

      $('#sidebar').hide();

      $('#sidebar').show();

      $('#sidebar').fade('slow');
