Does meta "Expires" tag affect website cacheing or indexing?
-
One of our client has a meta expire tag across all pages of their website.
Does that tag affect the website overall caching or indexing?
Their website pages including home page is crawled every 10 days, however the website is popular high traffic websites, receiving 240,000 visits/month.
Please advise what impact this tag will have on the website indexing and caching?
Thanks

It's most likely that Google is ignoring this, and will continue to ignore it.
There are just too many meta tags that you can include, and Google knows they're often used manipulatively. Unless you were using the meta expiry tag a lot and completely correctly, search engines will probably ignore it. (By correctly, I mean, use it for pages that actually do expire, then cutting off internal links after this date.)
That said, it's probably best to remove this tag.

Hi James,
The tag mentioned in itself is wrong and hence is not taken into consideration by search engines.
The correct tag should have been
Correct Format is :- Weekday followed with Date (Day Month Year) followed with Time Format as GMT/EST . This is basically the standard RFC format
Refer - http://www.w3.org/Protocols/rfc2068/rfc2068 for more details on RFC Format.
The tag if put correctly states an indication for search engine to delete expired documents from a search engine, unless been followed with a revisit tag
So, had the correct tag would have been put in place - all the pages would have been deleted from Google Index - as the tag states that the document is expired. It's a kind of 'nofollow' indication to Google. However, most of the Search marketers do not use meta expire tag, rather
- they 301 it, if the page has become redundant
or follow it it with revisit tag to let search engines to start crawling it from specified date onwards.

Thanks Gagan for the reply. However, you reply is more towards where to use, whereas my query is one of our clients has already used this tag on their website. So, would it affect their website's indexing or caching? Thanks.

To the best of my knowledge, Ideally Meta Expires is used for an Event. Suppose there is a music show or event - it may be wise to use Meta Expires as it indicates to Google to delete the page from index when the expiry time meets.

Directory website creation
Hi, I'm in the process of helping a client with a wedding show & supplier directory. Could anyone give me pointers as to the best practice for the architecture? Because the suppliers and shows will be listed geographically is there a possibility for the site to seem keyword stuffed? thanks, MOZ brain, you guys always rock.

What website changes (technical) SEOs can ignore confidently? Google's perspective!
Hi community members, I am looking after SEO at our company and there are lots of changes happening about our website; especially technical changes. It's hard for me to look after every deployment of the website like change of server location, etc. We generally agree that every change related to website must be notified by SEO to understand the ranking fluctuation and how search engines welcome them. I just wonder what technical deployments of a website I could confidently ignore to save time and give a go ahead to technical team without interrupting or waiting for my approval. Thanks

How to do a non-spammy "doorway page"?
Hi there, ISSUE: I have a client who wishes to use a "doorway" page, but not in a spammy way. He would like to have a nice crisp URL for use in ads/brochures. The page is strictly a landing page (just with a separate URL). DOORWAY/LANDING PAGE WILL BE: Non-spammy -- There will be no attempt to optimize the landing page/no attempt to get the page to rank. Strictly a vanity URL -- he likes the way a separate website looks in ads as opposed to a landing page on the existing website (i.e., www.websitename.com/landing page) WHAT I'M TRYING TO DO: I'm basically trying to figure out what the best things to do to protect his other sites (which are very high quality valuable sites which rank well) from getting punished. STEPS I'M CONSIDERING: Robots no follow Separate hosting server Different person's name on a private domain registration Adding additional pages, so it's not a 1-page "doorway" Many thanks in advance to anyone who would share their experience and help me protect my client in the best way possible. I've told him there are risks, but he still wants to go ahead. MC

Custom 404 Page Indexing
Hi - We created a custom 404 page based on SEOMoz recommendations. But.... the page seems to be receiving traffic via organic search. Does it make more sense to set this page as "noindex" by its metatag?

Duplicate Content for index.html
In the Crawl Diagnostics Summary, it says that I have two pages with duplicate content which are: www.mywebsite.com/ www.mywebsite.com/index.html I read in a Dream Weaver tutorial that you should name your home page "index.html" and then you can let www.mywebsite.com automatically direct the user to index.html. Is this a bug in SEOMoz's crawler or is it a real problem with my site? Thank you, Dan
