Visibility:hidden

[Meggy B]

Here is a tag we are testing - does anyone have any info on if Google or others will skip this tag or downgrade the site for it.
We use a tag ie: <div align="center" style="visibility:hidden; line-height:0px; ">bla bla bla</div>
Anyone here!

Actually, the visibility:hidden trick is one of the worst to use.

For sure you can increase substantially the amount of text in your web pages, with hopes bots will like it, but as spam indexing checks are becoming more and more accurate, doing so is taking great risk to get blaklisted by at least Google.

Again the Google Webmaster Guidelines are to be followed if you want your site to last in serps.

SEO number one matter is time : how long to wait until you get first spidered, to reach this amount of backlinks, to reach this ranking etc ...

Using visibility:hidden tag to hide content to human and spam search engine Bots is the kind of thing that could at first make things a little bit faster, but your take great risk to loose all the time spent online.
If you get blacklisted, you'll most likely have to fight harder to reach again the position you had just before.

I think a better way is to directly work on content, why hiding copies of it, making it longer and better will even work better as you won't just repeat things.

My advice is to avoid them right away, they are like keywords hidding (not visible but takes place in the layout) google warned about the use of such methods, eventhough they can be great for CSS layouts, they are still considered as back hat techniques.
In my opnion it's hard to say is it right or wrong to why google forbid that kind of practice (i mean the use of CSS technology) it sounds to be unfair but it is a trade-off that you should be wiling to take.

Thanks for information. But according to seo you will not use it because if it is come notice of google, your website will be ban because its come in Black hat SEO.

Google will penalize your website if they think you are tricking them. Doing fraud with CSS, divs or frames are all known so I would not recommend it to use..
