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

Redirection chain and Javascript Redirect
Hi, A redirection chain is usually defined as a page redirecting to another page which itself is another redirection. URL1 ---(301/302)---> URL2 ---(301/302)---> URL3 But what about Javascript redirect? They seem to be a different beast: URL1 ---(301/302)---> URL2 ---(200 then Javascript redirect)---> URL3 From what I know if the javascript redirect is instant Google counts it as a 301 permanent redirection, but I'm still not sure about if this counts as a redirection chain. Most of the tools (such as moz) only see the first redirection. So is that scenario a redirection chain or no?

Using 410 To Remove URLs Starting With Same Word
We had a spam injection a few months ago. We successfully cleaned up the site and resubmitted to google. I recently received a notification showing a spike in 404 errors. All of the URLS have a common word at the beginning injected via the spam: sitename.com/mono

sitename.com/mono.php?buy-good-essays
sitename.com/mono.php?professional-paper-writer There's about 100 total URLS with the same syntax with the word "mono" in them. Based on my research, it seems that it would be best to serve a 410. I wanted to know what the line of HTACCESS code would be to do that in bulk for any URL that has the word "mono" after the sitename.com/0 -
Create Page Titles from H1 using Yoast?
I'm working on a site that has 280 blog posts that have either been migrated from an old CMS site or created on the Dev version of the new WordPress site. We've written 280 unique meta descriptions so they don't truncate but it there a quick way I can export the current H1s and then import them into Yoast so they are set as the Page Titles? I've written unique Page Titles and meta descriptions for all the Service and Products page and just want a way to speed up the blog posts as their H1s are really good and what I would use as Page Titles anyway. Any help, greatly appreciated!

Canonical homepage link uses trailing slash while default homepage uses no trailing slash, will this be an issue?
Hello, 1st off, let me explain my client in this case uses BigCommerce, and I don't have access to the backend like most other situations. So I have to rely on BG to handle certain issues. I'm curious if there is much of a difference using domain.com/ as the canonical url while BG currently is redirecting our domain to domain.com. I've been using domain.com/ consistently for the last 6 months, and since we switches stores on Friday, this issue has popped up and has me a bit worried that we'll loose somehow via link juice or overall indexing since this could confuse crawlers. Now some say that the domain url is fine using / or not, as per - https://moz.com/community/q/trailing-slash-and-rel-canonical But I also wanted to see what you all felt about this. What says you?

Ok to internally link to pages with NOINDEX?
I manage a directory site with hundreds of thousands of indexed pages. I want to remove a significant number of these pages from the index using NOINDEX and have 2 questions about this: 1. Is NOINDEX the most effective way to remove large numbers of pages from Google's index? 2. The IA of our site means that we will have thousands of internal links pointing to these noindexed pages if we make this change. Is it a problem to link to pages with a noindex directive on them? Thanks in advance for all responses.

Using Sitemap Generator - Good/Bad?
Hi all I recently purchased the full licence of XML Sitemap Generator (http://www.xml-sitemaps.com/standalone-google-sitemap-generator.html) but have yet used it. The idea behind this is that I can deploy the package on each large e-commerce website I build and the sitemap will be generated as often as I set it be and the search engines will also be pinged automatically to inform them of the update. No more manual XML sitemap creation for me! Now it sounds great but I do not know enough about pinging search engines with XML sitemap updates on a regular basis and if this is a good or bad thing? Can it have any detrimental effect when the sitemap is changing (potentially) every day with new URLs for products being added to the site? Any thoughts or optinions would be greatly appreciated.

Using Schema.org: Product or Event as the schema type?
Hello, Most of you heard from the launch of the new format for microdata: Schema.org and my question is about the different types of Schema they provide. Our websites provide an overview of courses, visitors can search/filter training courses and most important: read peer reviews. Until now we formatted (the source) of those courses with the schema type "Product" because it allows us to provide search engines with metadata about reviews via the "Aggregrated Rating". Recently we updated the information about courses, to also provide start dates and locations to users, just like the schema type for: "Events". Because we would like to provide search engines also with both types of data I would like to know your opinion. Schema.org looks like not to support the Aggregated Rating for Events and vice versa for Startdates/Locations for the Product type. And combining the two Schema types also does not looks like an option because we can't put them on the same level like it should be. So what would you recommend to use for kind of schema type(s), are we able to use the 'Product' type next to the 'Event' type and so to combine them? Thanks a lot!
