How does a collapsed section affect on page SEO?
-
A client recently asked me whether a tabbed collapsed section of text that is expanded (i.e. revealed) when clicked, is an OK thing to do without negatively effecting SEO.
I told him that for starters, he may want to rethink why he would want to hide the text in the first place (this is not an FAQ type scenario). The reason has to do with the aesthetic of the page.
Anyway, aesthetic aside, any thoughts on whether a collapsed (hidden from view) negatively affects on-page SEO?
Thanks.

As long as the search engine can read all the text, I see no issues. Modern designers put text in multiple tabs or partially hidden until expanded all the time these to create a better user experience. It is generally only hidden from the user using css and is fully visible in the code.

Hi Stephan,
Presuming the expand/collapse thing is done properly, it should be golden. You'll find a lot of sites use this approach when they have multiple pages of content, e.g. a product page with specifications, reviews, technical details, etc.
I do this on my travel website. A great way to test to see if the initially-collapsed content is being seen and indexed by Google is to take a block of text from the collapsed section and search for it in double-quotes.
Here's an example: search for "At the Bora Bora Pearl Beach Resort you can discover the sparkling magic of the lagoon". You'll find my site there at #3 (Visual Itineraries), along with the other 1000 websites who've also copied the resort's description straight from the resort's website (yeah, I really shouldn't do this). So much for Google's duplicate content detection when it comes to text chunks...BUT I DIGRESS. That content you see is on the More Info tab.
Now, on to what "done properly" means:
- each tab should be in a separate div
- assign all divs a class which has style="display:none;" EXCEPT the currently selected tab
- have onclick handlers for the tabs that set all of the divs' classes to the display:none class, and then set the newly selected tab's div class to one with display:block or display:inline
And not done properly would mean something like changing the text of a div with Javascript onclick()....because Google won't see that text in the Javascript. It's got to be in the HTML.
That's about it. Not so tricky, really. And works well both for usability (no roundtrip to the server, not even an Ajax fetch!) and for SEO (lotsa yummy content on a single page for Panda).

Is it better to keep a glossary or terms on one page or break it up into multiple pages?
We have a very large glossary of over 1000 industry terms on our site with links to reference material, embedded video, etc. Is it better for SEO purposes to keep this on one page or should we break it up into multiple pages, a different page for each letter for example? Thanks.

Should I optimize my home-page or a sub-page for my most important keyword
Quick question: When choosing the most important keyword set that I would like to rank for, would I be better off optimizing my homepage, or a sub page for this keyword. My thinking goes as follows: The homepage (IE www.mysite.com) naturally has more backlinks and thus a better Google Page Rank. However, there are certain things I could do to a subpage (IE www.mysite.com/green-widgets-los-angeles ) that I wouldn't want to do to the homepage, which might be more "optimal" overall. Option C, I suppose, would be to optimize both the homepage, and a single sub-page, which is seeming like a pretty good solution, but I have been told that having multiple pages optimized for the same keywords might "confuse" search engines. Would love any insight on this!

Getting the Titles and Headings Right on Product Pages. Userbility vs SEO
Hey Mozzers, I am optimising a chaotic section of the site including many similar products. Writing unique content etc. The titles and urls were all over the place so my first job was to tidy them up so I could make some sense of the situation, especially as sometimes they didn't even match! I should point out were on Magento, so product name = Both the Heading and Title of the page, the meta title can be set separately. When i refer to title I mean both <title>and <h1></strong><br /><br />Before they existed as such<br />URL: domain.com/200-x-0-5-g-rs-232-balance.html<br />TItle: PC-1234 200 x 0.5g x 0.3 RS-232 Balance<br /><br />This format was (Product Code, Capacities, Resolutions, Accuracy, Product Title)<br /><br />The issue was all 60 products in a page followed this format. Navigating through the page was a nightmare and was just a jumble of numbers and highly confusing even to me who learnt what they all mean, especially when you had 8 products from the same range you got presented with<br /><br />APC-1234 200 x 0.5g x 0.3 RS-232 Balance<br />APC-1235 500 x 1g x 0.3 RS-232 Balance<br />APC-1236 1000 x 2g x 0.3 RS-232 Balance<br />APC-1238 5000 x 10g x 0.3 RS-232 Balance<br />APC-1239 10000 x 15g x 0.3 RS-232 Balance<br />APC-1210 20000 x 25g x 0.3 RS-232 Balance<br />APC-1211 50000 x 50g x 0.3 RS-232 Balance</p> <p>I changed them to something more user friendly.<br /><br />URL: domain.com/200g-precision-balance.html<br />Title: 200g Precision Balance<br /><br />This has seen the following benefits<br />- URL is now clear and means something to the user<br />- Product titles are easy to navigate and the page is more pleasing to the eye<br />- The jumble of numbers in the title are now all labelled and shown below each product listing in bullet point so the user can see the basic spec of a product without having to decipher any titles<br /><br />Upon reflection I has a couple of concerns I was hoping you could discuss, I am wondering if I have made the titles too simple.<br />1) I have no product code in the title<br />We have our own products manufactured and sell existing brands with their own product codes. Some of these can be lengthy. Adding them makes them hard to the eye and the page looked cramped.<br /><br />The codes are listed beneath each product title on category pages and on a list on the actual product page, but no where in the titles. <br /><br />2)None of our products have a brand listed in the title<br />None of the products on the site had brand names in anything but the images when i started and as such it snuck under my radar. But should i pre-fix all titles with a brand name?<br /><br />Should </p> <p>URL: domain.com/200g-precision-balance.html<br />Title: 200g Precision Balance</p> <p>become</p> <p>URL: domain.com/BRAND1-200g-precision-balance.html<br />Title: BRAND1 200g Precision Balance<br /><br />My instinct tells me to change things to include brands as its useful to the customer and should have an SEO benefit, but to leave out product codes as they are accessible to the customer where they are now and dont make things messy and unreadable.<br /><br />As always, thanks for the input!</p></title>

Hi! I need to add a splashpage to my wordpress site. I use "window.location" javascript on the homepage to redirect on the splashpage (controlled by cookie to redirect only for the first access). Can this technique affect the SEO on homepage? Thanks in advance!

ECommerce Filtering Affect on SEO
I'm building an eCommerce website which has an advanced filter on the left hand side of the category pages. It allows users to tick boxes for colours, sizes, materials, and so on. When they've made their choices they submit (this will likely be an AJAX thing in a future release, but isn't at time of writing). The new filtered page has a new URL, which is made up of the IDs of the filter's they've ticked - it's a bit like /department/2/17-7-4/10/ My concern is that the filtered pages are, on the most part, going to be the same as the parent. Which may lead to duplicate content. My other concern is that these two URLs would lead to the exact same page (although the system would never generate the 'wrong' URL) /department/2/17-7-4/10/ /department/2/**10/**17-7-4/ But I can't think of a way of canonicalising that automatically. Tricky. So the meat of the question is this: should I worry about this causing issues with the SEO - or can I have trust in Google to work it out?

301 redirects from several sub-pages to one sub-page
Hi! I have 14 sub-pages i deleted earlier today. But ofcourse Google can still find them, and gives everyone that gives them a go a 404 error. I have come to the understading that this wil hurt the rest of my site, at least as long as Google have them indexed. These sub-pages lies in 3 different folders, and i want to redirect them to a sub-page in a folder number 4. I have already an htaccess file, but i just simply cant get it to work! It is the same file as i use for redirecting trafic from mydomain.no to www.mydomain.no, and i have tried every kind of variation i can think of with the sub-pages. Has anyone perhaps had the same problem before, or for any other reason has the solution, and can help me with how to compose the htaccess file? 🙂 You have to excuse me if i'm using the wrong terms, missing something i should have seen under water while wearing a blindfold, or i am misspelling anything. I am neither very experienced with anything surrounding seo or anything else that has with internet to do, nor am i from an englishspeaking country. Hope someone here can light up my path 🙂 Thats at least something you can say in norwegian...
