Organic search traffic dropped 40% - what am I missing?
-
Have a client (ecommerce site with 1,000+ pages) who recently switched to OpenCart from another cart. Their organic search traffic (from Google, Yahoo, and Bing) dropped roughly 40%. Unfortunately, we weren't involved with the site before, so we can only rely on the wayback machine to compare previous to present.
I've checked all the common causes of traffic drops and so far I mostly know what's probably not causing the issue. Any suggestions?
- Some URLs are the same and the rest 301 redirect (note that many of the pages were 404 until a couple weeks after the switch when the client implemented more 301 redirects)
- They've got an XML sitemap and are well-indexed.
- The traffic drops hit pretty much across the site, they are not specific to a few pages.
- The traffic drops are not specific to any one country or language.
- Traffic drops hit mobile, tablet, and desktop
- I've done a full site crawl, only 1 404 page and no other significant issues.
- Site crawl didn't find any pages blocked by nofollow, no index, robots.txt
- Canonical URLs are good
- Site has about 20K pages indexed
- They have some bad backlinks, but I don't think it's backlink-related because Google, Yahoo, and Bing have all dropped.
- I'm comparing on-page optimization for select pages before and after, and not finding a lot of differences.
- It does appear that they implemented Schema.org when they launched the new site.
- Page load speed is good
I feel there must be a pretty basic issue here for Google, Yahoo, and Bing to all drop off, but so far I haven't found it. What am I missing?

Hi Adam,
Not to point out something that is likely well taken-care of, but did the GA / Analytics code populate across the site?
Also, is there any heavy JavaScript on the site, especially above analytics code, that might prevent analytics code from loading properly. We had this happen with a client a few years ago. We built custom analytics for this client (they did not want to run GA). Client placed our code in the footer. Client placed slow-loading CRO code in the header. CRO code took so long to load that people had often clicked away from the page they landed on before our code had had a chance to record their visit, as JavaScript generally loads in the same order as it's placed on the page. We had them move our little piece of code up to the top of the page. Problem was solved (in the mean time, we were recording a 20,000 visit loss each week!).
I'm just wondering if this is a tracking issue since all search traffic, not just Google has been affected. It would be quite rare to find an issue that has the same effect at the same time to both Bing and Google's algos. They're similar, but they're not identical and Bing generally tends to take longer to respond to change than Google as well.
Any chance you have raw server logs to compare analytics stats to?

I don't see anything that I would think would trigger that. Let me PM you the URL.

Did the layout of the header area change significantly? If, for instance, the header area went from 1/10th of the "above the fold" area to 1/3rd, that might run the entire site afoul of the "topheavy" part of Panda.

Thanks for the suggestions!
-
The homepage, category, and product pages have all lost traffic.
-
So far, I haven't found any noteworthy changes in content.
-
I've been wondering if this might be part of the issue.
-
I've reviewed Majestic link data, and only see a few deleted backlinks, so I'm thinking it's not a backlink issue.

Thanks for the suggestion. So far the only significant difference in optimization I've found has been that they added Schema.org markup.

Possibilities:
- The layout of the product pages for the new shopping cart is pissing off Panda. If that's the case, the traffic to the home page shouldn't have changed much, but the product pages will have dropped.
- Panda now sees the pages in general as having less content than before, perhaps images aren't getting loaded in the pages in such a way that Google sees them whereas they were before, something like that....and Panda now thinks the entire site is less rich in content.
- It often seems to take Google a month or so to "settle out" all of the link juice flows when you do a bunch of redirects, have new URLs, etc. I would expect that the link juice calculation is iterative, and that would be why it would take a number of iterations of the PageRank calculation in order for entirely new URLs to "get" all the link juice they should have.
- Their backlinks were moderately dependent upon a set of link networks, and those link networks have shut down all their sites (so that neither Google nor Bing still see the links from them).
Those are the ideas that come to mind so far.

Did the new cart generate product pages that were differently optimized than the old cart? (if cart-generated product pages were used)

Sudden Drop from #1 to #12
Hello Moz community,
Intermediate & Advanced SEO | | Marcmayo
I am really happy to be here and I start right away with a quite tricky question I'd say. We are running Star-Registration.com and in March switched platforms to Shopify. All the Redirects etc were done according to standards. Nevertheless, Star-Registration.com dropped in May (2 months after the switch) for "name a star" and "buy a star" from #1 to the 2nd Page of Google Results after being on #1 for almost 3 consecutive years. We had a similar case with their german website but the german one is back on the top 3 rankings again for all the important keywords. I attached a Screenshot of the Search Console stats
Any suggestions? yv6pep0 -
Missing Google verification
I just went to check my client sites in Google search console and noticed a whole bunch of them no longer 'verified'. They were all previously verified. Why would they suddenly change status to 'not verified'? Does this affect anything (eg. search analytics data flowing through to GA)? Does this mean I have to verify all over again?

Why have my rankings dropped?
I have a client who has just seen his average page rank creep up from around 39 to 34 over about two months, then it appears to have dropped back to position 40+ in the space of a week. I believe he's made a lot of changes to targeted keywords, so I'd like to think it's simply because his old targeted keywords are dropping and new keywords still have to build their rankings. But I'm also worried in case he has over-optimised and might get getting penalised. Any advice on where to start digging?

How to increase the traffic and keywords ranking

I have checked the webmaster tools for any mails and messages but I did not find any. So can anyone please visit the site and check it and please give me the suggestions accordingly to increase the traffic and keywords. Also I would like to know the advantages of commenting in Youtube.com.

Do search results differ greatly when you search on mobile?
If you have a site with responsive design, is Google likely to look upon you more favourably and dramatically change rankings?

Ranking drop for a particular page on a particular keyword
Take a look at centerforhealthysex.com/sex-addiction. For months we were ranking in the top 3 spots with this URL for "sex addiction los angeles", even reaching #1 for a while. Late last year we redesigned and developed the site to clean up the code and redirects. We also cleaned up the internal linking structure. For years we had been ranking on "sex addiction los angeles" for the home page ... bumping around the top 5 spots, but we wanted organic traffic to go to /sex-addiction. In the Fall, we saw overall site traffic rise steadily. We made few changes to the site and none to this page or links flowing back to the page once we had achieved strong ranking -- we didn't want to mess with a good thing. Then November 27th we started losing ranking on this term and a couple others. The good news is that we gained ranking on some high volume traffic terms so overall organic traffic is reasonably strong, BUT we're not ranking on the terms where we want to rank. Centerforhealthysex.com/sex-addiction is now nowhere to be found on the target search term despite fairly strong page rank. I tried redoing and resubmitting the site map, cleaning out some potentially duplicative content but to no avail. I see no issues, errors or warnings in Webmaster Tools. We have a few medium priority fixer-uppers in SEO Moz, but we've taken care of the majority of the big stuff. What am I not seeing? Thank you!
