How does using a CMS (i.e. Wordpress/Drupal) affect backlinks and SEO?
-
So I need to build a website with over 100 pages in it. Elements of the design will probably be moved around and or tested so I need to use a CMS. It's pretty much a review site so while the content will remain static I'd like to employ A/B testing to mess with conversion rates. Wordpress has a plugin for that even.
So I'm just wondering, since CMS pages are pretty much created on spot and not retrieved from a library, how this affects backlinks and anchor text? How exactly does the external website point to yours if the URL is dynamically generated?
Or am I misunderstanding something? Please recommend any extra resources as well if you can.

Sorry, saw the follow-up, but I think the overall thread has you covered. The only real issue with CMS URLs is that you can sometimes have multiple versions pointing to the same page, and this creates duplicate content. There are plug-ins for WordPress that can help with that.
The only exception would be something like an AJAX-style URL, where the page content could change without the URL ever changing (Flash has the same issue, for example). You'll rarely see that in a standard CMS, though, and definitely not in WordPress.

Thank you very much CMC-SD, Jared and goodlegaladvice for all your help.
@CMC-SD: As promised, I stole your analogy (Now I realize it was an analogy and not a metaphor, I think) and I tried to explain CMS to my girlfriend who knows nothing about computers. Unfortunately it did not come out as elegantly as you put it and we ended up eating bison burgers instead.
-
Ditto to that Jared. Great explanation. And now I'm hungry.

Oh, okay, I definitely misunderstood. You're asking about the back-end rewriting process that makes a pretty URL point to the corresponding ugly URL which in turn points to the page. That's way back-end. Unlike a 301 redirect, it's invisible to the spider. The spider need never know that a URL like http://www.domain.com/?p=123 even exists. While it's crawling, it sees a link to http://www.domain.com/page1.html, follows the link, and sees the HTML for that page. That's all.

@CMS-SD: Great metaphor! I'm going to steal it But I already knew that about CMS's xD. In fact my confusion was about what follows from that... If the pages are created dynamically and not retrieved from the webserver itself, how do would a backlink even REFER it??
I actually found this SEO blog touching on the subject matter: http://www.seomoz.org/blog/url-rewrites-and-301-redirects-how-does-it-all-work
So, pretty much this is how it works: A page is linked through the URL that is randomly generated by a CMS, but the webserver rewrites the URL that points to the original URL. Pretty much the same thing. And google indexes that URL plus the html on the page. Is that about right? That is why I should not worry at all.

Thanks! That's what happens when a creative writing major learns php.

This is probably the most well constructed, and humorous explanation on this that I have ever read. Bravo.

No. What "indexing" means is creating a database of URLs and the HTML that those URLs point to. If your site has been "indexed," it means Google has discovered your URLs and taken note of the HTML that can be found at those URLs.
-
I think you are misunderstanding something, yes.
On a website with a CMS, the URL is not "dynamically generated." The page is dynamically generated. Here's what that means. Whenever you type http://www.domain.com/page1.html into your browser, you are telling your browser to go to that website and pull up the HTML that corresponds to that URL. URL stands for "uniform resource locator," meaning directions to the location of a resource. If you have an old-fashioned website, the URL points to an HTML file that you created, either by typing everything yourself of using a WYSIWYG editor. If you have a CMS, the URL essentially instructs your website to build the corresponding HTML page on the fly.
It's like ... okay, imagine that you walk into a bakery and ask for a chocolate chip cookie. They could either pull a pre-baked chocolate chip cookie off the shelf and hand it to you, or walk in the back and bake you one cookie from the ingredients in the kitchen. When we're talking about baked goods, option 1 is almost always better than option 2 because it's orders of magnitude faster and more efficient. The benefits that option 2 offers aren't worth the extra time and lost efficiency. But when we're talking about websites, that's no longer the case. The server can construct an HTML document almost instantaneously. Your browser gets the HTML just as fast as it would if it asked for a static HTML page.
In fact, your browser really has no idea that this is all happening. Here's another food metaphor. You walk into a fast food joint and order a hamburger. The cashier walks into the kitchen, and a minute later, walks out with your hamburger. Did the cashier pull the hamburger off a shelf of hamburgers that have been sitting under a hotlight for hours? Or did the cashier ask the cook to prepare a fresh hamburger just for you? Assuming the hamburger tastes great either way, you have no way of knowing. In this metaphor, the customer is the surfer, the cashier is the browser, and the kitchen is the server your website is hosted on. Either your server has a bunch of pre-made pages sitting around waiting for someone to "order" them, or your server has a clever program that makes the pages only when they're needed. That clever program, the CMS, is like the short-order cook.
The thing to remember is, the search engine spiders are customers, just like the surfer. They don't know what's going on in the kitchen. They don't care. They "typed in" a URL and got some HTML back. They now know that that URL produces that HTML. They remember that. When they see a link to that URL, they know it's pointing to that HTML.
Clear as mud?

Ahhh, so Google indexes URLs and not the pages themselves? D'oh.

"So I'm just wondering, since CMS pages are pretty much created on spot and not retrieved from a library, how this affects backlinks and anchor text? How exactly does the external website point to yours if the URL is dynamically generated?"
Firstly, different CMS's create pages differently. CMS just means content management, which means the platform just provides a gui for you to add content or make changes. If you are using WP and creating pages, then these pages wil be indexed as any other page, and links pointing to it would simply target the page's URL.
Wordpress uses permalinks and Drupal uses pathauto to redirect platform generated links into SEO friendly one. They use an internal redirect and the resulting URL is indexed in Google. Therefore, you simply treat the resulting URL as the "real" url, and external links to it work fine.

right no difference I took a whole site with statics and changed it over to a cms with all rewrites everything works great kept the urls the same though kept the .htm
-
I was under the impression that URL rewrites just change the way the URL is displayed on the browser but not the URL itself. I really need to learn more about the backend stuff.
So it would make no difference if the backlink contained an absolute path?
-
It works the same as a static page except its easy to manage your content....
You usually also use a url re-write agent that can change your urls to say what ever you want. In fact most of the web is now on a cms.
Backlinks, Anchor text is all the same....

Is this spammy/panda problem?
We have a property site and have many area pages with listings of properties. For example, one page may have up to 30 properties listed, with 100 words of description on that listing page for that property and then you click 'more info' to get to the page of that property with maybe 200 words in total. I want to add bullet points for each property on the area page but Im worried that it may be seen by google as spammy even though its usefull to the client. For example, if I had 30 properties on a page, and 28 of them said next to each picture.. Property Type: Shared, Open Plan, Single Bed Would that be a problem for google?

Main page redirect affecting search results?
Question.... A recent change was made to our page www.BGU.edu by a marketing person. So now when you type in www.BGU.edu it actually redirects to a different page www.BGU.edu/inquiry This is a really bad idea isn't it? I do not know enough about SEO to know a lot, and just joined SEOmoz but do I need to tell the admin to change it back?

I need help with international SEO for two sites?
I'll try to keep this clear... I am working with an company based in Germany, they own company.com/de and company.com/en, and that's how they are currently structuring their domains. They also own companyusa.com that they really want to show up in USA only. They want to keep company.com/en for England/english speaking Europe and company.com/de for their German audience in Germany. They are wanting us to optimize/SEO for companyusa.com, and they want that URL to show up as the top google search in the USA for their "company" keyword. What is showing up now is www.company.com/en 1st in Google because it's been around longer and it has more domain authority. What is the best practice for us optimize companyusa.com so that it is the top dog in the USA while not messing up the other domains? Should we merge? Subfolders all around? Thanks for all the input.

Using More Info javascript:toggleDisplay tag for More info text
Is there any harm in using javascript so a user can "toggle" open or closed additional text on a website? For example, if a user wants to read more about something, they can click on "More Info" and the text would then appear. Google is able to read the text, because I chose a random 8 word section of the text within the More Info and pasted it into a Google Search and the website showed up in search results. Just wondering if using this technique would have any negative impact. Here's what the code would look like:
Web Design | | EEE3
<a <span="">title</a><a <span="">="Show Tables" href="</a><a class=" " target="_blank">javascript:toggleDisplay('table1')</a>">More Info style="display: none;" id="table1"> this is where the text would be, and from this section was where I grabbed text to search with in google. Then in the footer, here is the script needed so the more info will work: I am by no means an expert in coding/html/javascript. Thanks!0 -
SEO and Modal Windows
Hi all, My website has a Login and Join Us option on every page in the site. Each Login and Join Us window pops up as a modal window. In other words, the user must interact with it before they are taken somewhere else (whether they close it or fill it in). It has come to my attention that this is being counted as duplicate content. Is there any way around this? It's calling duplicate content on practically the whole website. Thanks in advance!

Seo for flash home page?
I have a client who insists their home page be a single graphic image of their logo with php menus linking to all of the other pages up top. This appears to me to be an seo nightmare. They seem to be unwilling to have anything to do with changing the appearance and want to rely on seo for "all the other pages" on the site. What's an SEO to do in this situation? Is it possible to have a flash image that lands on a "homepage" for google to crawl, rather than a single image? What's the best seo approach here?
