Hi, I have a doubt. If we want to hide unwanted text in a web page its possible with "" tag. And my question "does a search engine crawl those text? help me.

I want to hide a lot of text behind my site page. I know its possible with that tag. But in what way a search engine looks at those text? Hidden or they are crawled and indexed.

What you're trying to achieve is called cloaking, which will get your site banned - unless you decide to do it using comment delineators (as you mentioned).

If you do it using those delineators, good news! You won't get banned!!
(bad news though: you'll be totally wasting your time).

you will not be penalized why that text is not indexed, it will be as a comment line in html (I think)

Can you say why you want to hide this text? If you could give us an example, it'll help us help you a bit more.

If the text is unwanted remove it completely from the page as this will improve fractional page load speed which does effect ranking. Having comments in your HTML other than for development reasons is pointless. Google will ignore anything commented.

Hi,

I have lots of keywords. I know violations of google in hiding keywords behind a page using different ways. So, i want to go for another way which was apart from that. Is there any way to add more keyword excluding Alt tags, meta tags. And i have a lot text which we want to display periodically, so hiding text in that location is a best idea for us.

The best idea maybe is write this keyword in your content with bolded text or insert in h1,h2,h3. Your need a logical content, not only keyword, your content need give some to your visitors. And adding some backlinks with your keywords variety to your website.

Try create some landing page with a specific keyword and link this page with your project principal page. I recommend use de moz One-page Optimization for gets more information.

Important don't hide text in your website

What you have proposed in your question is using the comment tag, which is generally meant for comments to someone who is reading the source code of the page and working on the HTML of a website. For example, identifying that the following section is the Google Analytics script and please don't remove it.

If you want Google to see the keywords, you need to show your users the keywords.

Yeah hiding keywords in your page is definitely not cool with Google.  Many people do it by making the text the same color as the background.  No one can see it, unless they highlight the area.  Used to be effective, now it's just spammy and will get you banned.
