Hi Moz Community, I have a question about personalization of content, can we serve personalized content without being penalized for serving different content to robots vs. users? If content starts in the same initial state for all users, including crawlers, is it safe to assume there should be no impact on SEO because personalization will not happen for anyone until there is some interaction? Thanks,

Hi Moz community, Our tech team has recently decided to try switching our product pages to be JavaScript dependent, this includes links, product descriptions and things like breadcrumbs in JS. Given my concerns, they will create a proof of concept with a few product pages in a QA environment so I can test the SEO implications of these changes. They are planning to use Angular 5 client side rendering without any prerendering. I suggested universal but they said the lift was too great, so we're testing to see if this works. I've read a lot of the articles in this guide to all things SEO and JS and am fairly confident in understanding when a site uses JS and how to troubleshoot to make sure everything is getting crawled and indexed. https://sitebulb.com/resources/guides/javascript-seo-resources/ However, I am not sure I'll be able to test the QA pages since they aren't indexable and lives behind a login. I will be able to crawl the page using Screaming Frog but that's generally regarded as what a crawler should be able to crawl and not really what Googlebot will actually be able to crawl and index. Any thoughts on this, is this concern valid? Thanks!

Hi Moz Community, We're an eCommerce site so we have a lot of pagination issues but we were able to fix them using the rel=next and rel=prev tags. However, our pages have an option to view 60 items or 180 items at a time. This is now causing duplicate content problems when for example page 2 of the 180 item view is the same as page 4 of the 60 item view. (URL examples below) Wondering if we should just add a canonical tag going to the the main view all page to every page in the paginated series to get ride of this issue. https://www.example.com/gifts/for-the-couple?view=all&n=180&p=2 https://www.example.com/gifts/for-the-couple?view=all&n=60&p=4 Thoughts, ideas or suggestions are welcome. Thanks

I recently filtered query information by week and day. The impression and click totals were different depending on whether I looked at totals by a full weeks or by day. So for example, the impression and click totals when I choose a date range of  monday-sunday are different when I look at impressions and clicks that same week by day and then add up the click and impression numbers to get a weekly total. At first i was expecting a slight difference since I know the data is heavily sampled but the totals were very different. Any explanations for this? Thanks

Hi Moz Community, We've been implementing new canonical tags for our category pages but I have a question about pages that are found via search and our filtering options. Would we still need a canonical tag for pages that show up in search + a filter option if it only lists one page of items? Example below. www.uncommongoods.com/search.html/find/?q=dog&exclusive=1 Thanks!

Hi all, Two weeks ago i noticed that one of our pages which normally ranks in the top 5 of search results dropped out of the top 50 results. I checked to make sure there were no Google penalties and checked to make sure the page was crawlable. Everything seemed fine and after a few hours our page went back into the number one position. I assumed it was a Google Flux. This number one ranking lasted about a week, today I see my page has dropped out of the top 50 yet again and hasn't come back up. again there are no penalties and there doesn't seem to be issues with the page. I'm hoping it comes back up to the top by tomorrow. What could be causing such a big dip multiple times?
