How does badly formatted HTML affect SEO?
-
Our website uses a custom built CMS, but uses a fairly standard WYSIWYG text editor.
I've looked at some of the code it produces, and it's not pretty. My gut feeling tells me that this extra bloat is bad for SEO.
Am I right in thinking that Google doesn't look kindly upon badly formatted and bloated HTML?
Thanks,
James -
Great, thanks for the info. I always thought Google was really hot on compliance, but good to know there is a bit of leeway.

James, You might also want to look at the cached version of your page and then click on Text-only version and see if it shows up correctly. If it does, no need to worry from that perspective, but definitely worth checking from a usability, accessibility etc.
-
The main concern is whether or not the spider can read the HTML. If something's broken, the spider may get confused. It's a good idea to check the site's W3C compliance and correct what you can, but I'm certain the search engines don't ding you if you're not perfectly compliant.
The real problems with bad HTML are load times and cross-browser compatibility. (Although, frankly, great HTML can have cross-browser compatibility issues, since IE still refuses to get with the program.) Make sure the site looks good in all major browsers.
-
As long as the code produced is readable in a web browser then it being bloated shouldn't have much of an impact in terms of SEO. The code bloats only downside is that it might slow the page load which will have impact on SEO. Remember crawlers like Google bot essentially look at the page content in terms of textual content, what labels (alt tags etc), images and links are on there not how neatly it is presented or whether it is valid markup or not. I would take a look at your page speed otherwise I would worry as long as it is able to fulfil all the basic on page requirements such as headers, page titles etc.
Just to reiterate this - I have worked with CMS driven sites that aren't W3C compliant and don't produce the nicest html, but have loaded fast and ranked in the top 3 for competitive terms.

Why is pagination SEO such a mystery in 2021?
Hi folks. I would like to discuss pagination. I use WordPress (Genesis, specifically). I ran my site through a site scan and it flagged an error which told me that my blog was producing duplicate meta descriptions because the blog is paginated - the same meta description from the blog page is being used on Page 2, Page 3 etc. I looked into this and the Internet is awash with many other people scratching around for a solution. My understanding is that using a canonical link on the first page is not a good idea, because it says to Google that only Page 1 of the blog is important. I also read an article that states Google no longer reads the Rel=Prev/Next code that could be used to tell Google to ignore the issue. So, what's the solution? Do I even need one? As a side-thought, it seems to me that pagination is, well, pretty useless. I mean, if my blog has 20 pages and I've worked hard to create content, who is going to click through to anywhere near page 20? Nobody. There has to be a smarter way for people on-site to access content. I would love your thoughts on all of this. Cheers.

How does product category description affect SEO?
Hi - we are a website that sells tours. We have category pages that list the tours in that category (by city, by length of time, theme, etc). At the top of each category page, before the buttons linking to the tours, there is a category description. It is a pretty long paragraph. We are redesigning the website and think it would look nicer to show 2-3 lines of text and then have a down arrow and 'read' more so people can click and it would expand to show the full category description if they want to read it and it won't take up so much room that way. My question is - will this affect SEA at all? Or because the text is still there, just hidden, it won't do anything? Our site ranks very high in organic searches on google and we do not want to do anything that will hurt SEO. thanks.

Is an iframe redirect on the same Domain bad for SEO
Good morning. We have a vendor that has created a landing page with content that we want to use. Because of the way we built the site, the only way to use the content is to create an i-frame. The i-frame is re-directingon the same Domain. Would we benefit from the SEO Content?

SEO on dynamic website
Hi. I am hoping you can advise. I have a client in one of my training groups and their site is a golf booking engine where all pages are dynamically created based on parameters used in their website search. They want to know what is the best thing to do for SEO. They have some landing pages that Google can see but there is only a small bit of text at the top and the rest of the page is dynamically created. I have advised that they should create landing pages for each of their locations and clubs and use canonicals to handle what Google indexes.Is this the right advice or should they noindex? Thanks S

How will changing my website's page content affect SEO?
Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. Thanks!

Is it bad for SEO to have a page that is not linked to anywhere on your site?
Hi, We had a content manager request to delete a page from our site. Looking at the traffic to the page, I noticed there were a lot of inbound links from credible sites. Rather than deleting the page, we simply removed it from the navigation, so that a user could still access the page by clicking on a link to it from an external site. Questions: Is it bad for SEO to have a page that is not directly accessible from your site? If no: do we keep this page in our Sitemap, or remove it? If yes: what is a better strategy to ensure the inbound links aren't considered "broken links" and also to minimize any negative impact to our SEO? Should we delete the page and 301 redirect users to the parent page for the page we had previously hidden?

Is Using a Question, Answer Format Appropriate for a Blog? Is a 300 Word Micro Blog An SEO Plus?
My PR agency has suggested a question answer format be incorporated in my blog. They suggest a microblog with a single sentence question and an answer of about 300 words. My blog currently has about 35 posts. I would like to ramp up blog entries to about one or two per week of these "mini blog" posts. The format of the new blog begins as a question with the responses being paragraphs that do not use headings. My concerns are as follows: 1. No headings in an answer of 300 words will fail to provide Google with context regarding the content's meaning. Everything I have read about SEO suggests text be broken up in short sections and that it be divided by headings (preferably H2s). I very much like my agency's concept for a question answer format blog. It provides very practical info for visitors. How can I use it in a manner that supports SEO best practices? 2. According to a reputable SEO firm that has been assisting me, Google does not consider a blog post of less than 600 words to be superior quality. They told me that blog posts of 300 words, from an SEO purpose will not be a great helpful, that the content will not be rich enough to generate incoming links. Is this really the case? What if this abbreviated content is very well written and engaging? If so, is 300 words sufficient? From the visitor's perspective I am not sure they would have the patience to read 600 words when 300 words is more than than enough to answer these basic questions. From a PR perspective I think the shorter content in a question answer format is superior at least for my line of business (commercial real estate brokerage). 3. If 500-600 words is the minimum word count, and headings are necessary, what is the best way to execute a question and answer blog format? The purpose of this blog is to provide very useful info to my visitors while generating incoming links to that will boast my rankings. Thanks in advance for your feedback!!! Alan

Does domain WhoIs Privacy affect SEO efforts?
Hi guys, I got a hopefully quick question. I am designing a site currently that is made up of many different domain names as part of a network. I've heard that Google will penalize however is linking is passed back and forth between these domains if the registrant information was the same. I have WhoIS privacy information on all the domains to stop telemarketers and spam as well as (hopefully stop Google from getting suspicious). I'm not doing anything bad or against Google rules but I can see how they might think that if I have a huge network and links are being passed between these. It's a friend of mine who owns like 2000 domains and he wants to put legitimate information on each one and rank them higher, it's an interesting concept but I won't go into to much detail. So my question is basically, does having WhoIS privacy on all these domains, will it affect me in anyway in the SEO process? Will google count the links passing back and forth as legitimate? Or might it get suspicious and think I am spam? Are there ways to see what server it's coming from? Should all these sites be on different servers? Any help is much appreciated!
