Spam pages / content created due to hack. 404 cleanup.
-
A hosting company's server was hacked and one of our customer's sites was injected with 7,000+ pages of fake, bogus, promotional content.
Server was patched and spammy content removed from the server.
Reviewing Google Webmaster's Tools we have all the hacked pages showing up as 404's and have a severe drop in impressions, rank and traffic. GWT also has 'Some manual actions apply to specific pages, sections, or links'...
What do you recommend for:
- Cleaning up 404's to spammy pages? (I am not sure redirect to home page is a right thing to do - is it?)
- Cleaning up links that were created off site to the spam pages
- Getting rank bank // what would you do in addition to the above?
-
You want those old spam pages to have a 410 code - gone (permanently). I'm not 100% sure how you will achieve this though... I'd speak to your hosting company and/or web developer.
404 code means the page is 'not found' which isn't the same as 410, which tells the search engines that the page has gone forever, so they won't keep looking for it.
Hope this helps!

Duplicate content on Places to Stay listings pages
Hello, I've just crawled our website https://www.i-escape.com/ to find we have a duplicate content issue. Every places to stay listing page has identical content (over 1,500 places) due to the fact it's based on user searches or selections. If we hide this pages using canonical tags, will we lose our visibility for each country and/or region we promote hotels? Any help on this would be hugely appreciated! Thanks so much Clair

Partial duplicate content (reviews) on product pages - is this ok?
Hello, we recently received some really good reviews about a range of products we sell (there are normally 8 products in a range). Due to the industry we are in it made no sense to try and get reviews on each individual product within the range as they differ only ever so slightly. So my question is we want to add these reviews to each of the 8 products that lie within each range, but by adding them it would mean that each page has around 600 words of unique product description followed by approx 600 words of reviews that are the same on each of the products within that range. Is this ok? my only other option would be to screenshot the reviews and upload them as images below each product description. If anyone could offer advice here that would be much appreciated. Thanks

How to avoid duplicate content on internal search results page?
Hi, according to Webmaster Tools and Siteliner our website have an above-average amount of duplicate content. Most of the pages are the search results pages, where it finds only one result. The only difference in this case are the TDK, H1 and the breadcrumbs. The rest of the layout is pretty static and similar. Here is an example for two pages with "duplicate content": https://soundbetter.com/search/Globo https://soundbetter.com/search/Volvo Edit: These are legitimate results that happen to have the same result. In this case we want users to be able to find the audio engineers by 'credits' (musicians they've worked with). Tags. We want users to rank for people searching for 'engineers who worked with'. And searching for two different artists (credit tags) returns this one service provider, with different urls (the tag being the search parameter) hence the duplicate content. I guess every e-commerce/directory website faces this kind of issue. What is the best practice to avoid duplicate content on search results page?

Container Page/Content Page Duplicate Content
My client has a container page on their website, they are using SiteFinity, so it is called a "group page", in which individual pages appear and can be scrolled through. When link are followed, they first lead to the group page URL, in which the first content page is shown. However, when navigating through the content pages, the URL changes. When navigating BACK to the first content page, the URL is that for the content page, but it appears to indexers as a duplicate of the group page, that is, the URL that appeared when first linking to the group page. The client updates this on the regular, so I need to find a solution that will allow them to add more pages, the new one always becoming the top page, without requiring extra coding. For instance, I had considered integrating REL=NEXT and REL=PREV, but they aren't going to keep that up to date.

Duplicate page content
Hello, My site is being checked for errors by the PRO dashboard thing you get here and some odd duplicate content errors have appeared. Every page has a duplicate because you can see the page and the page/~username so... www.short-hairstyles.com is the same as www.short-hairstyles.com/~wwwshor I don't know if this is a problem or how the crawler found this (i'm sure I have never linked to it). But I'd like to know how to prevent it in case it is a problem if anyone knows please? Ian

Advice and Opinions Required Regarding creating new pages for similar keywords
We are currently in the process of creating new pages for keywords very similar to our main landing pages. Example: Page 1.) "Family Holiday in {Location}" Page 2.) "Family Vacation in {Location}" Page 3.) "Family get-away in {location}" All 3 keywords are currently optimised for the 1st page "Family Holidays in {Location}" but was wondering if there is any benefit or if its worth creating sub pages for these alternative keywords. I personally don't think we should do this as Google will know to rank our main page for secondary/synonym keywords via on page seo and links with anchor text, but can you foresee any negative aspects if we went ahead and created these children pages being linked to from the top level keyword's page? Or do we continue optimising our main landing page for related/synonym keywords? Thanks in Advance GREG

How unique does a page need to be to avoid "duplicate content" issues?
We sell products that can be very similar to one another. Product Example: Power Drill A and Power Drill A1 With these two hypothetical products, the only real difference from the two pages would be a slight change in the URL and a slight modification in the H1/Title tag. Are these 2 slight modifications significant enough to avoid a "duplicate content" flagging? Please advise, and thanks in advance!

Mitigating duplicate page content on dynamic sites such as social networks and blogs.
Hello, I recently did an SEOMoz crawl for a client site. As it typical, the most common errors were duplicate page title and duplicate content. The client site is a custom social network for researchers. Most of the pages that showing as duplicate are simple variations of each user's profile such as comment sections, friends pages, and events. So my question is how can we limit duplicate content errors for a complex site like this. I already know about the rel canonical tag, and rel next tag, but I'm not sure if either of these will do the job. Also, I don't want to lose potential links/link juice for good pages. Are there ways of using the "noindex" tag in batches? For instance: noindex all urls containing this character? Or do most CMS allow this to be done systematically? Anyone with experience doing SEO for a custom Social Network or Forum, please advise. Thanks!!!
