Any SEO effect(s) / impact of Meta No Cache?
-
Hi SEOMoz Guys,
Hope you guys are doing well.
I've been searching online and bumped into this archived page (http://www.seomoz.org/qa/view/34982/meta-nocache-affect-ranking). I would like to get an updated take on this issue whether or not the meta no cache code on a page bears negative/positive or no SEO impact / effect.
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Cache-Control" content="no-cache"/>
Thanks!
Steve

Alan, thank you for this response. I was completely off base thinking of the noarchive tag and that is what my response was geared towards. Your response is dead on, and I agree, adding the noarchive tag should be fine but it may send a weak signal to Google your site may be hiding something.

I just had a read, about the noarchive, I found where http://www.seroundtable.com/archives/017128.html
Where it is claimed that Matt Cutts has said there is no penalty, BUT, if you have spammy signals it will be another signal.
so there is some truth in it, but only if you ae already a bit spammy.
I also found this video
http://www.youtube.com/watch?v=XhrZKejdmEEMatt mentioned it here. if you have been hacked, they may show he hacked page only to googlebot, so this can not be checked they also add noarchive.
so if they suspect a hack, and you have noarchive, you may have a problem, but he also stated in anouther videio that they will tell you you hhave a problem. -
Yes I am. I think you are talking of
where the syntax steve posted is for caching in the browser and proxy servers. -
Hi Ryan,
Thanks for citing another source. I'm actually doing a site audit for a client and noticed that most, if not all, of their pages have the meta no cache on the script code. To be honest, it is the first time I've come across this and was unsure if it would have any SEO impact.
Thanks again!
Steve

Alan, I just want to make sure we are talking about the same thing here. I believe the original question refers to cache as it appears on Google search results pages. Based on your responses it seems as if you are referring to web page cache on the site's web server. Am I mistaken?
-
Why would you take it as less trustworthy.
simply having dynamic content is reason enouth to have no cache. no-caching is widly used, you can no cache all or part of a page if anything i would say the oppersite, if you are cached you may get indexed less often.
for example you should not cache a page with sensitive data, and allow someone to click the back button at a later time and get the data.
Search results is anouther example, I am sure that google and Bing do not cache their search results.
News papers is another.

no it would not have any affect, no-cache is a requirement for many sites that have dynamic content. Why would SE's want to penalize you for having dynamic content.
Caching does give you faster loading times, but as someone posted from google, you have to be very slow to get flaged for slow load times and less then 1% of pages do, even then it is a small signal.
-
I am not aware of any negative SEO impact to adding the no-cache meta tag. The answer provided in the Q&A link you shared seems accurate and complete.
The Google page which discusses using no-cache clearly states "The page will still be crawled and indexed by Google, but users will not see a Cached link in the search results."
With the above understood, I would also ask the same question from the Q&A response....why would you want to no cache your page? The only valid reasons I can think of are for a page being developed or otherwise under constant change. We don't know all aspects of Google's algorithm but I would take a non-cached page as less trustworthy then a cached page.

Homepage SEO optimization
Hello, I’m almost ready to lunch my new website https://thetravelhoop.com , I just need to create the content of the product page and put all the images. I would like to know what you think in terms of SEO of the home page (is the content that I want to rank the most). My doubt is that since it is a landing page, there is not a lot of text but mostly <h>. It’s not a styling decision of course (I know is bad practice) but mostly because they are supposed to be title/headings.</h> Do you think I’m doing something wrong, or do you have any suggestions? Thank you, Daniele

Does using Yoast variables for meta content overwrite any pages that already have custom meta content?
The question is about the Yoast plugin for WP sites. Let's say I have a site with 200 pages and custom meta descriptions / title tags already in place for the top 30 pages. If I use the Yoast variable tool to complete meta content for the remaining pages (and make my Moz issue tracker look happier), will that only affect the pages without custom meta descriptions or will it overwrite even the pages with the custom meta content that I want? In this situation, I do want to keep the meta content that is already in place on select pages. Thanks! Zack

SEO audit on a beta site
HI there, Is there much point conducting an SEO site audit on a site that has not yet launched and is protected behind a login? Presumably none of the usual SEO tools (Moz, Screaming Frog etc) can crawl this site becuase it is all locked behind a login. Would it be better to launch it and then do a site audit? Thanks

Two URL's for the same page
Hi, on our site we have two separate URL's for a page that has the same content. So, for example - 'www.domain.co.uk/stuff' and 'www.domain.co.uk/things/stuff' both have the same content on the page. We currently rank high in search for 'www.domain.co.uk/things/stuff' for our targeted keyword, but there are numerous links on the site to www.domain.co.uk/stuff and also potentially inbound links to this page. Ideally we want just the www.domain.co.uk/things/stuff URL to be present on the site, what would be the best course of action to take? Would a simple Canonical tag from the '/stuff' URL which points to the '/things/stuff' page be wise? If we were to scrap the '/stuff' URL totally and redirect it to the 'things/stuff' URL and change all our on site links, would this be beneficial and not harm our current ranking for '/things/stuff'? We only want 1 URL for this page for numerous reasons (i.e, easier to track in Analytics), but I'm a bit cautious that changing the page that doesn't rank may have an affect on the page that does rank! Thanks.

How will it effect SEO to have multiple h1 tags on a page?
I have a client who recieved this advice from his marketing consultant: "If there are multiple h1 tags on a page, this can confuse Google and it may have a negative impact on the keyword rankings. If you could ask your web developer to go in and remove the h1 tags on the header images that would be helpful. This way it will be easier for Google to index your site and will help your keyword rankings." How will it effect SEO to have multiple h1 tags on a page?

Does keyword at the very front of meta description have impact?
I know that it is important to have your primary keyword target as the first word or two words of your title tag. But what about your meta description tag? does it matter where they keyword is in the description tag? I see a lot of other sites stuffing their keywords right at the front of the description tag and it looks somewhat unnatural. What's your take? do you put the primary keyword as the first word or two words of your description tag?

Is a Z almost as good as an S?
Possibly seems a strange question, but let me clarify... I have a new site in mind and all the domain names I was considering for it have been taken (I want a .com or a .net if at all possible). However, I can get the domain with a z at the end rather than an s Example: www.keyword-guides.com is taken, but www.keyword-guidez.com is available. Am I completely wrong in thinking that it will still match well for anyone searching Keyword Guide, and should match fairly well (even though it is a partial match) for people searching Keyword Guides. As the keyword is the most relevant bit of the domain, and as the first word on the domain is given the most weight, will having Z instead of S at the end make any difference at all? Personally, I don't really like the Z option, but if it would have no (or little) impact on my SEO efforts, I could live with it.
