Would using javascript onclick functions to override href target be ok?

Hi all,
I am currently working on a new search facility for me ecommerce site... it has very quickly dawned on me that this new facility is far better than my standard product pages - from a user point of view - i.e lots of product attributes for customers to find what they need faster, ability to compare products etc... All in all just better. BUT NO SEO VALUE!!!
i want to use this search facility instead of my category/product pages... however as they are search pages i have "robots noindex them" and dont think its wise to change that...
I have spoken to the developers of this software and they suggested i could use some javascript in the navigation to change the onlclick function to take the user to the search equivelant of the page...
They said this way my normal pages are the ones that are still indexed by google etc, but the user has the benefit of using the improved search pages...
This sounds perfect, however it also sounds a little deceptive... and i know google has loads of rules about these kinds of things, the last thing i want is to get any kind of penalty or any negative reaction from an SEO point of view... I am only considering this as it will improve the user experience on my website...
Can any one advise if this is OK, or a "no no"...
P.s for those wondering i use an "off the shelf" cart system and it would cost me an arm and a leg to have these features built into my actual category / product pages.

Hello James,
Why do these pages have "no SEO value"? Is it because they are AJAX pages or because you have them noindexed? Or both?
To answer your original question, using an on-click javascript event to send a user to a page other than the URL listed in the href tag is borderline. It goes beyond the risk level I would feel comfortable with on an eCommerce site, but a lot of affiliate sites do this. For instance, all of their links out to merchant sites may go through a directory called /outlink/ so the href tag might look like .../outlink/link1234 and appear to send the user to another page on their domain, when actually the user gets redirected to the merchant's (e.g. Amazon.com, Best Buy...) website. Sometimes the user is redirected from the /outlink/... URL and sometimes they never even get that far because the javascript sends them to the merchant's URL first.
It is not cloaking unless you are specifically treating Google differently. If Google doesn't understand your site that is their problem. If you have code that essentially says "IF Google, THEN do this. ELSE do that" it is your problem because you are cloaking. Make sense? There is a very distinct line there.
The bottom line is if you want to show users a certain page then you should be showing that page to Google as well. If the problem is the content on that page doesn't appear for Google (e.g. AJAX) then you should look into optimizing that type of content to the best of your ability. For example, look into the use of hashbangs (#!) as in:

1. Google understands simple JS that is inline with your HTML. So Google understands that
is a link to domain.com. You can obfuscate this further and Google might not understand it. I've not seen Google try to parse or execute JS but that doesn't mean they can't or won't in the future.3. Google is very unlikely to spider AJAX. Many AJAX pages don't return any user readable content (most of mine return things like JSON, which is not for end user consumption) and , as such, are beyond the scope of indexation. Again, as in #2, you might want this content to be shown elsewhere if you want it indexed. https://developers.google.com/webmasters/ajax-crawling/

ok, i am not keen on this approach, the developers have offered an alternative... but again, i'm not sure about it, they have said they can use ajax to force their search results / navigation over my current navigation / products on my category / product pages...
this gets rid of having to use javascript to send to different url... but up above Alan mentions cloaking, which to my understanding is basically serving anything different for a search engine / person... and thats what this will do... it serves up a different navigation to people... and the products could be listed in a different order etc... search engines do not see the ajax...
Is this any better? or just as negative?
-
Are they identical, you say the search equivalent, I just wouldn't treat search engines any different
-
even thou the content is identical?
It is only the way that content can then be navigated that is different...
-
Well then, yes I would be concerned, you are serving up different content to users, that is cloaking.

Hi Alan,
i think i may have explained incorrectly - my search page does have the meta tag noindex,follow - it also has a canonical link back to the main search page (i.e search.html) so i do not think any of the search results will be indexed. So my concern is not duplicate content, this should not happen...
My concern is the fact i am using javascript to litterally divert customers from one page to another... its almost like the static pages are there only for the benefit of google... and thats concerning me...
-
Google can follow JavaScript links, unless you are very good at hiding them.
I would not worry too much about the duplicate content, don't expect the duplicates to rank, but your not likely to be penalized for them. you can use a canonical tag to point all search results back to the one page.
I would not no index any pages, any links pointed to a no-index page are pouring their link juice away. if you want to no index a page use the meta tag no-index,follow, this way the search engine will follow the links and flow back out to your site

Correct use of schema for online store and physical stores
I have been getting conflicting advice on the best way to implement schema for the following scenario. There is a central e-commerce store that is registered to it's own unique address which is "head office". There are a few physical shops each of which has their own location and address. Each shop has its own landing page within /our-stores/. So each page on the website has the Organisation schema for the central 'organisation', something like: Then on each physical store landing page is something like the following as well as the Organisation schema: Is this correct? If it is should I extend LocalBusiness with store URL and sameAs for GMB listing and maybe Companies House registration? It's also been suggested that we should use LocalBusiness for the head office of the company, then Departmentwith the typeStore. But i'm not sure on that?

If you use canonicals do the meta descriptions need to be different?
For example, we have 3 different subsites with the same pages. We will put canonicals so they reference the main pages. Do the meta descriptions have to be different for each of the three pages? How does Google handle meta data when using canonicals?

Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

302 redirect used, submit old sitemap?
The website of a partner of mine was recently migrated to a new platform. Even though the content on the pages mostly stayed the same, both the HTML source (divs, meta data, headers, etc.) and URLs (removed index.php, removed capitalization, etc) changed heavily. Unfortunately, the URLs of ALL forum posts (150K+) were redirected using a 302 redirect, which was only recently discovered and swiftly changed to a 301 after the discovery. Several other important content pages (150+) weren't redirected at all at first, but most now have a 301 redirect as well. The 302 redirects and 404 content pages had been live for over 2 weeks at that point, and judging by the consistent day/day drop in organic traffic, I'm guessing Google didn't like the way this migration went. My best guess would be that Google is currently treating all these content pages as 'new' (after all, the source code changed 50%+, most of the meta data changed, the URL changed, and a 302 redirect was used). On top of that, the large number of 404's they've encountered (40K+) probably also fueled their belief of a now non-worthy-of-traffic website. Given that some of these pages had been online for almost a decade, I would love Google to see that these pages are actually new versions of the old page, and therefore pass on any link juice & authority. I had the idea of submitting a sitemap containing the most important URLs of the old website (as harvested from the Top Visited Pages from Google Analytics, because no old sitemap was ever generated...), thereby re-pointing Google to all these old pages, but presenting them with a nice 301 redirect this time instead, hopefully causing them to regain their rankings. To your best knowledge, would that help the problems I've outlined above? Could it hurt? Any other tips are welcome as well.

How to generate a visual sitemap using sitemap.xml

Does google use the wayback machine to determine the age of a site?
I have a site that I had removed from the wayback machine because I didn't want old versions to show. However I noticed that in many seo tools the site now always shows a domain age of zero instead of 6 years ago when I registered it. My question is what do the actual search engines use to determine age when they factor it into the ranking algorithm? By having it removed from the wayback machine, does that make the search engines think the site is brand new? Thanks

How to use overlays without getting a Google penalty
One of my clients is an email subscriber-led business offering deals that are time sensitive and which expire after a limited, but varied, time period. Each deal is published on its own URL and in order to drive subscriptions to the email, an overlay was implemented that would appear over the individual deal page so that the user was forced to subscribe if they wished to view the details of the deal. Needless to say, this led to the threat of a Google penalty which _appears (fingers crossed) _to have been narrowly avoided as a result of a quick response on our part to remove the offending overlay. What I would like to ask you is whether you have any safe and approved methods for capturing email subscribers without revealing the premium content to users before they subscribe? We are considering the following approaches: First Click Free for Web Search - This is an opt in service by Google which is widely used for this sort of approach and which stipulates that you have to let the user see the first item they click on from the listings, but can put up the subscriber only overlay afterwards. No Index, No follow - if we simply no index, no follow the individual deal pages where the overlay is situated, will this remove the "cloaking offense" and therefore the risk of a penalty? Partial View - If we show one or two paragraphs of text from the deal page with the rest being covered up by the subscribe now lock up, will this still be cloaking? I will write up my first SEOMoz post on this once we have decided on the way forward and monitored the effects, but in the meantime, I welcome any input from you guys.

How to handle sitemap with pages using query strings?
Hi, I'm working to optimize a site that currently has about 5K pages listed in the sitemap. There are not in face this many pages. Part of the problem is that one of the pages is a tool where each sort and filter button produces a query string URL. It seems to me inefficient to have so many items listed that are all really the same page. Not to mention wanting to avoid any duplicate content or low quality issues. How have you found it best to handle this? Should I just noindex each of the links? Canonical links? Should I manually remove the pages from the sitemap? Should I continue as is? Thanks a ton for any input you have!
