Will invalid HTML code generated by WordPress affect SEO efforts?
-
Hi all, I'm new to SEOmoz and SEO in general really. I run a small but well regarded freelance website and graphic design business, and until very recently had an employee who handled the SEO side of things. I'm now looking to step into this role myself and hopefully learn the in's and out's of SEO. I've no doubt there will be much to learn, but the SEOmoz tools and it's community seem excellent and helpful.
My question then is basically, if WordPress generated HTML code can have an effect on SEO, when it's reported as invalid by tools such as the W3C HTML validator?
I'm used to hand coding the majority of my websites for clients, where creating valid HTML and CSS code is something I can do with relative ease. A new client however wants to use WordPress - for ease of updating the site content themselves. The client does however consider any potential SEO implications to be a very important factor in choosing a hand coded vs. WordPress based website.
I am aware that WordPress itself is just a means of generating HTML code, and that to the search engines there is no difference between this and the hand coded websites I usually produce. However if WordPress is generating HTML that is being reported as invalid, would this make the search engines penalise the site?
On a second note, will the search engines look negatively on a WordPress site where it is being used as a standard website, and the content may not be updated as frequently, as say, a blog?
Thanks for your time, and I look forward to hearing your suggestions.

Thanks for the quick reply, it's much appreciated. I had guessed that it wouldn't be a major issue, but wanted to be a bit more certain before going ahead with the WordPress site for the client.
The errors certainly don't have a negative effect on the sites' layout, content, usability or load times. From what I can tell they are due to the theme making use of iframes and video embeds in a non-standard manner. The rest of the HTML is sound. As you also mentioned, it does seem to be related to the theme the client wants to use, as with other themes I can get valid HTML code output.

Depends on the kinds of errors being generated. I use wordpress and it does not generate errors like that for me. It may be the theme you are using.
Anyways, invalid markup plays a very minimal role in seo. The primary way it effects things is with site speed. If there are errors that may impact your site's load time then yes it can penalize you a little. But not enough where you will really see that negativity. If the rest of your site is properly optimized you would be fine. It is minor problems that compound and add up which will create a headache for you.

SEO implications of network outage
Hi, Our bandwidth provider has informed us of a forthcoming network outage this weekend, the net result being that around 20 websites will be unreachable for a total of about 1 hour inside a predetermined 3 hour window.In an ideal world we would like to provide a holding page or be able to respond with a "503 Service Temporarily Unavailable" HTTP code, however the complete absence of connectivity means we'll be unable to do this.Does anyone have any ideas about the SEO implications of this kind of downtime? It would be useful to know if there are any actions we can take prior to the outage that could mitigate the impact. We've considered repointing the DNS to other servers, but it's only something we'll do if the negative impact of not doing it is too great.Thanks in advance!

Auto generated pages
Hi, I have two sites showing (crawl report from SEOMoz.org) extremely high numbers of duplicate titles and descriptions (e.g., 33,000). These sites have CMSs behind them and so the duplicate titles, etc., are a result of auto-generated pages. What is the best way to address these problems? Thanks! David

SEO for a franchise business
Were about to embark on an SEO project for a franchise business with about 150 franchises. Would it be best to give all of the franchises individual domain names or house them under the one domain? If they were on the same domain would it be worth setting them up with sub domains or with a URL so city.mydomain.com vs mydomain.com/city Thanks
