Clean HTML codes for better indexing?

I would like to know if clean HTML codes provide for better indexing? Also where can I check this?


I am new to coding and do not know how to clean my HTML codes on my own. Is there any service that provides this? Thank you

 

I think so. I've read that you should transfer Scripts and CSS codes into an external file because it can make a page bigger. This is beneficial to spiders since they do not read and spiders crawl only a limited size of data from the pages.

 

1. Validate every page with this tool _http://validator.w3.org_
2. Use divs, not tables.
3. Use SSI, not iframes.

etc...

 

<div>s do not automatically give you cleaner mark-up. Nor should they be looked at as a replacement for <table>s. <table>s are for tabular data. A <div> is a generic block-level container.

This:

<div id="container">
  <div id="title">Page Heading</div>
  <div>Content</div>
</div>

Code (markup):

is no better than:

<table id="container">
  <tr>
    <td id="title">Page Heading</td>
  </tr>
  <tr>
    <td>Content</td>
  </tr>
</table>

Code (markup):

Use semantic mark-up. Separate presentation from content through CSS.

Frames offer functionality that is simply not possible to achieve with Server Side Includes.

 

Thank you guys. I will look into this.

 

for the most part, I don't think it matters much for SEO.

it has tons of other advantages-- ease of changing the layout without modifying the content, among other things-- but SEO isn't really at the top of the list.

I've got some horribly coded, old sites that get tons of traffic from google.

 

Thanks -- Interesting website
