Is z-indexing a black-hat trick?
-
I use z-indexing for a floating bar that scrolls vertically along the side of my page. I'm not hiding anything. Is this safe or not?
-
You're good then. It's the negative z index implementations that have issues.
-
It's completely visible. I'm just using "z-index: 1;" I'm not using a negative number. It's for a java floating box that scrolls along side the page with the user. It just makes the floating box stay on top, but it's only covering a couple pixel widths of white space behind it.

you say its for a floating bar that scrolls vertically. Is it hidden from a site visitor or visible? If it's a negative z index, it could be "perceived" as a problem by Google's automated system. They claim that your intent counts. Except I've never seen Google guarantee that they'll assign a human to review every single site that is flagged with potential problems. This is why you "should probably be okay if you're not using it to fool Google" but where they consistently communicate "we have a right to do what we want to do" and thus, when in doubt, consider the risk/reward to make your decisions.

Z-indexed content
I have some content on a page that I am not using any type of css hiding techniques, but I am using an image with a higher z-index in order to prevent the text from being seen until a user clicks a link to have the content scroll down. Are there any negative repercussions for doing this in regards to SEO?

How can I tell Google not to index a portion of a webpage?
I'm working with an ecommerce site that has many product descriptions for various brands that are important to have but are all straight duplicates. I'm looking for some type of tag tht can be implemented to prevent Google from seeing these as duplicates while still allowing the page to rank in the index. I thought I had found it with Googleoff, googleon tag but it appears that this is only used with the google appliance hardware.

Odd scenario: subdomain not indexed nor cached, reason?
hi all hopefully somebody can help me with this issue 🙂 6 months ago a number of pages hosted at a domain level have been moved to a subdomain level with 301redirects + some others were created from scratch ( at a subdomain level too). what happens is that not only the new urls at the subdomain level are not indexed nor cached, but the old urls are still indexed in google, although by clicking on them they bring to the new urls via 301 redirect. question is why having a 301 redirects to the new urls, no issues with robot.txt, metarobots etc, the new urls are still de-indexed? i might remind you that a few (100 pages or so) have been created from scratch, but they are also not indexed. the only issue found across the page is the no-cache line of code set as follow: Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache i am not familiar with cache control lines. Can this be an issue from a correct indexing? thanks in advance Dario

Sitemap indexed pages dropping
About a month ago I noticed my pages indexed from my sitemap are dropping.There are 134 pages in my sitemap and only 11 are indexed. It used to be 117 pages and just died off quickly. I still seem to be getting consistant search traffic but I'm just not sure whats causing this. There are no warnings or manual actions required in GWT that I can find.

Dev Site Was Indexed By Google
Two of our dev sites(subdomains) were indexed by Google. They have since been made private once we found the problem. Should we take another step to remove the subdomain through robots.txt or just let it ride out? From what I understand, to remove the subdomain from Google we would verify the subdomain on GWT, then give the subdomain it's own robots.txt and disallow everything. Any advice is welcome, I just wanted to discuss this before making a decision.

Sitemap nos being indexed
Hi! How are you? I'm having a problem: for some reason I don't understand, Google Webmasters Tool isn't indexing the sitemaps I'm uploading. One of them is http://chelagarto.com/index.php?option=com_xmap&sitemap=1&view=xml&lang=en . Do you see what could be the problem? It says it only indexed 2 website. I've already sent this Sitemap several times and I'm always getting the same result. I'd really use some advice. Thanks!

How do I eliminate indexed products?
Please help! We got clobbered by Penguin and are at risk of having to close down after 10 years. We have been trying to figure out why and believe now it might be because of duplicate content. We added 2" inserts in March (over 500): http://www.trophycentral.com/inserts1.html Even though each is a different products, SEOMOZ is saying they are considered duplicate content. Given the timing, we think this might be the cause, even though it is totally legitimate. Question - since these are now indexed and since we can't easily add content quickly, what is the best way to handle this situation? A no-index tag? Is there a way to let Google know that their algorithm is detroying legitimate businesses??

Domain restructure, sitemaps and indexing
I've got a handcoded site with around 1500 unique articles and a handcoded sitemap. Very old school. The url structure is a bit of a mess, so to make things easier for a developer who'll be making the site database-driven, I thought I'd recategorise the content. Same content, but with new url structure (I thought I'd juice up the urls for SEO purposes while I was at it) To this end, I took categories like: /body/amazing-big-shoes/
Technical SEO | | magdaknight
/style/red-boots/
/technology/cyber-boots/ And rehoused all the content like so, doing it all manually with ftp: /boots/amazing-boots/
/boots/red-boots/
/boots/cyber-boots/ I placed 301 redirects in the .htaccess file like so: redirect 301 /body/amazing-boots/ http://www.site.co.uk/boots/amazing-boots/ (not doing redirects for each article, just for categories which seemed to make the articles redirect nicely.) Then I went into sitemap.xml and manually overwrote all the entries to reflect the new url structure, but keeping the old dates of the original entries, like so: <url><loc>http://www.site.co.uk/boots/amazing-boots/index.php</loc>
<lastmod>2008-07-08</lastmod>
<changefreq>monthly</changefreq>
<priority>0.5</priority></url> And resubmitted the sitemap to Google Webmasters. This was done 4 days ago. Webmaster said that the 1400 of 1500 articles indexed had dropped to 860, and today it's climbed to 939. Did I adopt correct procedure? Am I going about things the right way? Given a little time, can I expect Google to re-index the new pages nicely? I appreciate I've made a lot of changes in one fell swoop which could be a bit of a no-no... ? PS Apologies if this question appears twice on Q&A - hopefully I haven't double-posted0
