Suspicious external links to site have 302 redirects
- 
					
					
					
					
 Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/ 
 http://www.chinamarbles.com.cn/
 http://www.china-slate.com.cn/
 http://www.granitecountertop.com.cn/

 Linda, OK, thanks. Grateful to have another opinion on it. It seems like this site has suffered, but the rest of links look reasonable. However, the previous SEO done appears to have been link building with complete absence of keyword research and subsequent optimisation of pages, posts, etc. Regards, Steve

 As strict as Google can be, I have never heard of them penalizing anyone for something bad they used to do (but didn't get caught at) and have now stopped doing. I think they reserve their penalties for current bad actions. [Which is not to say you were doing something bad--we are talking about your wanting to be sure that it doesn't appear to Google that you tried something bad.] In general, I think it's best not to disavow unless it is an extreme situation. As Google itself says: "In most cases, Google can assess which links to trust without additional guidance, so most normal or typical sites will not need to use this tool."

 Linda, Thanks. It appears that the domains are all owned by the same / person entity and could it be that there is any legacy effect of having these links prior to 302? Regards Steve

 Since the links are using 302 redirects they are not passing any link juice, so I can't imagine that you'd be penalized for them.

		Is this campaign of spammy links to non-existent pages damaging my site?
 My site is built in Wordpress. Somebody has built spammy pharma links to hundreds of non-existent pages. I don't know whether this was inspired by malice or an attempt to inject spammy content. Many of the non-existent pages have the suffix .pptx. These now all return 403s. Example: https://www.101holidays.co.uk/tazalis-10mg.pptx A smaller number of spammy links point to regular non-existent URLs (not ending in .pptx). These are given 302s by Wordpress to my homepage. I've disavowed all domains linking to these URLs. I have not had a manual action or seen a dramatic fall in Google rankings or traffic. The campaign of spammy links appears to be historical and not ongoing. Questions: 1. Do you think these links could be damaging search performance? If so, what can be done? Disavowing each linking domain would be a huge task. 2. Is 403 the best response? Would 404 be better? 3. Any other thoughts or suggestions? Thank you for taking the time to read and consider this question. Mark White Hat / Black Hat SEO | | MarkHodson0

		Moz was unable to crawl your site? Redirect Loop issue
 Moz was unable to crawl your site on Jul 25, 2017. I am getting this message for my site: It says "unable to access your homepage due to a redirect loop. https://kuzyklaw.com/ Site is working fine and last crawled on 22nd July. I am not sure why this issue is coming. When I checked the website in Chrome extension it saysThe server has previously indicated this domain should always be accessed via HTTPS (HSTS Protocol). Chrome has cached this internally, and did not connect to any server for this redirect. Chrome reports this redirect as a "307 Internal Redirect" however this probably would have been a "301 Permanent redirect" originally. You can verify this by clearing your browser cache and visiting the original URL again. Not sure if this is actual issue, This is migrated on Https just 5 days ago so may be it will resolved automatically. Not sure, can anybody from Moz team help me with this?

		How does Google determine if a link is paid or not?
 We are currently doing some outreach to bloggers to review our products and provide us with backlinks (preferably followed). The bloggers get to keep the products (usually about $30 worth). According to Google's link schemes, this is a no-no. But my question is, how would Google ever know if the blogger was paid or given freebies for their content? This is the "best" article I could find related to the subject: http://searchenginewatch.com/article/2332787/Matt-Cutts-Shares-4-Ways-Google-Evaluates-Paid-Links The article tells us what qualifies as a paid link, but it doesn't tell us how Google identifies if links were paid or not. It also says that "loans" or okay, but "gifts" are not. How would Google know the difference? For all Google knows (maybe everything?), the blogger returned the products to us after reviewing them. Does anyone have any ideas on this? Maybe Google watches over terms like, "this is a sponsored post" or "materials provided by 'x'". Even so, I hope that wouldn't be enough to warrant a penalty.

		Tags on WordPress Sites, Good or bad?
 My main concern is about the entire tags strategy. The whole concept has really been first seen by myself on WordPress which seems to be bringing positive results to these sites and now there are even plugins that auto generate tags. Can someone detail more about the pros and cons of tags? I was under the impression that google does not want 1000's of pages auto generated just because of a simple tag keyword, and then show relevant content to that specific tag. Usually these are just like search results pages... how are tag pages beneficial? Is there something going on behind the scenes with wordpress tags that actually bring benefits to these wp blogs? Setting a custom coded tag feature on a custom site just seems to create numerous spammy pages. I understand these pages may be good from a user perspective, but what about from an SEO perspective and getting indexed and driving traffic... Indexed and driving traffic is my main concern here, so as a recap I'd like to understand the pros and cons about tags on wp vs custom coded sites, and the correct way to set these up for SEO purposes.

		Hiding content or links in responsive design
 Hi, I found a lot of information about responsive design and SEO, mostly theories no real experiment and I'd like to find a clear answer if someone tested that. Google says: White Hat / Black Hat SEO | | NurunMTL
 Sites that use responsive web design, i.e. sites that serve all devices on the same set of URLs, with each URL serving the same HTML to all devices and using just CSS to change how the page is rendered on the device
 https://developers.google.com/webmasters/smartphone-sites/details For usability reasons sometimes you need to hide content or links completely (not accessible at all by the visitor) on your page for small resolutions (mobile) using CSS ("visibility:hidden" or "display:none") Is this counted as hidden content and could penalize your site or not? What do you guys do when you create responsive design websites? Thanks! GaB0

		Disavow - Broken links
 I have a client who dealt with an SEO that created not great links for their site. http://www.golfamigos.co.uk/ When I drilled down in opensiteexplorer there are quite a few links where the sites do not exist anymore - so I thought I could test out Disavow out on them .. maybe just about 6 - then we are building good quality links to try and tackle this problem with a more positive approach. I just wondered what the consensus was? White Hat / Black Hat SEO | | lauratagdigital0

		Site dropped suddenly. Is it due to htaccess?
 I had a new site that was ranking on the first page for 5 keywords. My site was hacked recently and I went through a lot of trouble to restore it. Last night, I discovered that my site was nowhere to be found but when i searched site: mysite.com, it was still ranking which means it was not penalized. I discovered the issue to be a .htaccess and it have been resolved. My question is now that the .htaccess issue is resolved , will my site be restored back to the first page? Is there additional things that i should do? I have notified google by submitting my site White Hat / Black Hat SEO | | semoney0

		Off-page SEO and link building
 Hi everyone! I work for a marketing company; for one of our clients' sites, we are working with an independent SEO consultant for on-page help (it's a large site) as well as off-page SEO. Following a meeting with the consultant, I had a few red flags with his off-page practices – however, I'm not sure if I'm just inexperienced and this is just "how it works" or if we should shy away from these methods. He plans to: guest blog do press release marketing comment on blogs He does not plan to consult with us in advance regarding the content that is produced, or where it is posted. In addition, he doesn't plan on producing a report of what was posted where. When I asked about these things, he told me they haven't encountered any problems before. I'm not saying it was spam-my, but I'm more not sure if these methods are leaning in the direction of "growing out of date," or the direction of "black-hat, run away, dude." Any thoughts on this would be crazy appreciated! Thanks, Casey White Hat / Black Hat SEO | | CaseyDaline0
