What does this meta tag do?

what does this meta tag do and is is good / bad for seo?

<meta http-equiv="cache-control" content="no-cache" />

 

I think it doesn't allow SE to cache the page

 

it wont allow SE to cacde your pages, nor to cache them in visitors computer, if i am not mistaken.

advantages - visitors see updates right away and never land on a cached version
disadvantages - more bandwidth wasted as the page will get reloaded full size every time.

 

Cheers, i think i will edit it out of my site then.

 

Meta tags for good for SEO. (too some extent). Without good content and back links, meta tags are nothing. But a good meta tag gives high CTR as people read title/description before clicking.

<meta http-equiv="cache-control" content="no-cache" /> doesn't allow SE to cache the page

 

Good for contantly updated site like stock news but may be unsuitable for an article or content-based site.

 

It has advantages and disadvantages. If your website is modified on a daily basis than it's good.
