Is hidden content bad for SEO?
-
I am using this plugin to enable Facebook comments on my blog:
https://wordpress.org/plugins/fatpanda-facebook-comments/This shows the comment in an Facebook iFrame. The plugin author claims it's SEO friendly, because the comments are also integrated in the WordPress database. The are included in the post but hidden.
Is that bad for SEO?

Providing an alternative way for search engines to access content that is not otherwise available to them, but is clearly available to anyone who "sees" the page is a legitimate use of the Display: None tag. Here is what Google has to say about it: http://www.seroundtable.com/google-hiding-content-17136.html .

Hm, I admit it's not so easy to explain the topic. Let me summarize it like this:
My site: WordPress
Issue: Regarding comments on a blog postComments: Usually WordPress uses it's own commenting system. Google can see the comments and this helps for SEO.
Comments on Facebook: To increase my comment rate, I am using a Facebook commenting plugin.
How does it work: Facebook uses an iFrame for comments, so they are visible in Front-End, but not in source code. But: The plugin is smart and takes those comments and puts them into the WordPress database. So WordPress shows the comments in the source code, but not in the Front-End. Only the Facebook comments are shown in the Front-End, but since it's an iFrame not in the source code.
So from Googles perspective the comments are visible in the source code, but they can't find them displayed in the front-end. The question is if that's a bad thing. The reason for me asking is, that some time back I read that lot's of black hats are using hidden content and that you should not do it.

Now I'm confused, you said "But it's not visible on front end side (except the Facebook comment iFrame)." Then "the hidden text is not inside the iFrame"
In the source code do you actually see the word iFrame?
-
In this case the hidden text is not inside the iFrame (WordPress comment database), and visible in the source code.
But it's not visible in the front-end.
-
Generally speaking anything in an iFrame will not be indexed for your site and therefore will provide no SEO benefit. So if the hidden text is within the iFrame this will have no positive or negative effect for your site.
-
That's a cool tool, didn't know that yet.
I used it and also checked in the source code. The hidden content is there. But it's not visible on front end side (except the Facebook comment iFrame).
Now is that bad?
-
A quick test for this would be to test your site in http://seo-browser.com and compare it to the same page source code (in browser right click 'View Page Source' or 'View Source' depending on browser) as I'm not sure what elements are being hidden

Content Strategy/Duplicate Content Issue, rel=canonical question
Hi Mozzers: We have a client who regularly pays to have high-quality content produced for their company blog. When I say 'high quality' I mean 1000 - 2000 word posts written to a technical audience by a lawyer. We recently found out that, prior to the content going on their blog, they're shipping it off to two syndication sites, both of which slap rel=canonical on them. By the time the content makes it to the blog, it has probably appeared in two other places. What are some thoughts about how 'awful' a practice this is? Of course, I'm arguing to them that the ranking of the content on their blog is bound to be suffering and that, at least, they should post to their own site first and, if at all, only post to other sites several weeks out. Does anyone have deeper thinking about this?

Are pop-unders bad for SEO?
Hi all, I run a travel site that specializes in hotel bookings. We're working with a third-party advertiser to launch a pop-under unit when someone searches for hotels on our site. (This unit is of the "also try your search on these competing sites" variety.) I'm worried, however, that this might affect our SEO, especially in light of this on their site: https://support.google.com/webmasters/answer/2721313?hl=en Would Google even see these pop-unders? (Are pop-unders treated the same as pop-overs?) And, if so, would G see them as unwanted and treat them as a nuisance? Could it lead to negative SEO consequences? Any thoughts would be appreciated. Thanks! Tom

Quick Question: Is it Bad for SEO to paste from Word to your CMS?
Hey just a quick question I'm having trouble finding a definitive answer to: Is the markup that is transferred from Word docs bad for SEO? We are managing to paste it and it looks fine, but the developers are worried that the extra code will be bad for SEO. Does anyone have solution besides pasting into Text Editor and formatting in the CMS? Is this necessary or can we just leave the extra code? Thank you!

Pagination & SEO
I have the WP-Pagination plugin and I am wondering how to handle duplicate content issues and what's best for SEO. My developer initially downloaded the plugin to speed up loading for the home page. Now my home page has 21 pages of paginated content. But the pagination continues with each of my categories as well. Should I be placing a canonical reference to my home page, or category main page? My site name is gracessweetlife (dot) com

What SEO tactics are effective for optimising a site where content is changing very frequently (for example an online newspaper)?
I have always worked with sites where content has a reasonably long life-span but need to now consider SEO for a site where content is changing very rapidly. I have read that Google will re-spider your content more frequently if it finds that it is changing frequently but are there effective ways to let the search engines know as new articles are published? Also, if content is removed within only a day or two of being published, can this have a negative impact on SEO?
