Welcome to the Q&A Forum

Google makes the decision, and it can actually be pretty hard to convince them to use your description rather than a snippet on the page.

Google says "Google will sometimes use the description tag from a page to generate a search results snippet, if we think it gives users a more accurate description than would be possible purely from the on-page content." (Bold is mine) https://support.google.com/webmasters/answer/35624?hl=en

Their page above is a pretty good starting point to guide you on how to write good descriptions.

Ah, sorry, I misunderstood.

"Review" is only a recommended property of "Product", so while you will get a warning, it should not be detected as an error and won't affect the structured data being parsed.

I don't think you'll have an issue, so long as you don't post thousands of spammy pieces all at once, make it look as natural as possible. To be fair, you usually get the most value if your pieces do offer genuine value.

I would normally suggest picking a few people within the company to post various categories of content depending on their role, but that is sometimes not appropriate or possible (e.g. one man band businesses)

What would a user who wasn't logged in see if they visited it?

Depending upon your company, I would suggest exposing the knowledgebase, that could possibly rank for people looking to solve problems that your products would help with. Same with the forum. If you chose to do that, you might be better off simply moving that content to somewhere else in your site structure.

For everything else, Google wouldn't typically be able to login, and what would you actually show it? It's not a customer, so it would have any tickets or products to list serial numbers of. You could detect that it's GoogleBot and show something else, but that's very bad practice!

Hi,

The url with the parameter won't be indexed by Google. On that page you have (correctly) got the canonical tag set to "https://www.tansleyphotography.co.uk/farnham-castle-wedding-claire-chris/" so you're telling Google (and all the other search engines) which is the "master" page that you want indexing. Therefore, Google should be fine.

You can tell Moz to ignore them by using robots.txt to exclude them for rogerbot:

User-agent: rogerbot
Disallow: /*?reply-to

(Note, that will tell rogerbot to not crawl any URL with "?reply-to" in it, you could use "/*?" if you wanted to block all parameters, which may or may not be desirable)

With that many pages, I assume you are already carefully managing structure and crawlability. I wouldn't think that about few thousand pages on a site of a million would make that much difference (Your new pages only make up 0.1% of your total site), if they're linked properly and included in the site map(s) correctly you shouldn't have much issue. I certainly wouldn't suggest drip feeding them in.

I assume you mean that your code is outputting empty review when there are no reviews? Are you using a plugin, or is it custom code?

If it's a plugin, I would suggest speaking with the plugin developer or raising it via their feature request process.

If it's custom code, then I'm afraid it is down to you! If there is no review for that product, don't output the microdata!

Google will often make up its own mind what to put in your description, especially if it thinks that your provided description doesn't match what it thinks the page is about.

I'm afraid your developer hasn't fixed the issue. I was looking in the wrong place (your screenshot identified the issue), the malware isn't replacing the meta description, but actually inserting text at the top of the page, but only when it detects that it is the Mobile Googlebot visiting.

Using Google Chrome Developer Tools you can set your user agent and see the issue yourself (See my screenshot)

If I were you, I'd disable all the plugins and then reload the page in Chrome with your user agent set and see if that helps, if not, I would look at your theme's JS/source files.

I can't see anything obvious. I did wonder whether it might be a script that only replaced the description when it was crawled by Google but I can't see any evidence of this.

If your developer is suggesting that they have removed the issue, I assume they did find a problem and have corrected it. When was it corrected? It may well just be a case of Google taking some time to update the index. You could check this in Search Console, use the URL Inspection and do a Live Test and then View Tested Page, check the source to see if the description is as expected.

If it is, I think it is likely just a case of waiting, given that you have already requested reindexing.

If the refresh was just because the site looked dated, why was all the content updated?

A complete rebuild of the site seems a little drastic if it only needed a facelift. Were there other concerns?

As Kevin asked, were 301s set up? if there were no 301's set up, any previous links will no longer be passing juice, which could have a serious impact.

Do you mean to see if Google has indexed it (even if it isn't ranking)? If so, Search Console is the answer. https://search.google.com/search-console/about

If you mean rankings for specific keywords/phrases, you might consider signing up to Moz

I might not have understood your question, so apologies in advance if that's the case.

Your redirects won't be temporary, they'll be permanent (301). As far as the search engines (and anyone else) are concerned, the location has moved permanently.

You can't really set a redirect (temporary or permanent) as nofollow. The redirect is a response code from the server, it's not a link. To be fair, you wouldn't want to set it to nofollow even if you could, you want the search engines to follow the redirection to the new place and index that.

If I understand you correctly, you are trying to use the review structure data?

Google's Structured Data Testing Tool is showing an error in your structured data:
https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fwww.mashhoor.ir%2Fblog%2F%25D9%2585%25D8%25B1%25D8%25A7%25D8%25AD%25D9%2584-%25D8%25AB%25D8%25A8%25D8%25AA-%25D8%25A8%25D8%25B1%25D9%2586%25D8%25AF-%25D9%2588-%25D8%25AB%25D8%25A8%25D8%25AA-%25D8%25B9%25D9%2584%25D8%25A7%25D9%2585%25D8%25AA-%25D8%25AA%25D8%25AC%25D8%25A7%25D8%25B1%25DB%258C%2F

There seem to be two problems. One, you're not actually returning a reviewRating. And two, Google doesn't like your value for rating count, I think it's because you're outputting numbers in Punjabi, e.g. ۲۵۸ (Apologies if that's not the right term) I think they need to use latin characters, but I may be wrong, you may be able to "tell" Google that you are using a different system.

I'd suggest referencing https://developers.google.com/search/docs/data-types/review-snippet

Hi,

1. You can exclude the Moz crawler (Rogerbot) from various pages: https://moz.com/help/moz-procedures/crawlers/rogerbot 
You need to use your robots.txt file, rather than trying to do it on page

2. Once you've done the above, you can request a recrawl and they should all disappear

Do you mean pages you initiate the search from, or the search results page? (I know these can be the same thing in some cases)

I would allow a page that you search from to be indexed, depending upon what it is used to search. Someone who has put a query into Google might find your search page useful in resolving their query.

I wouldn't allow search results pages to be indexed, for obvious reasons, even for specific searches links from other locations. You'd be better off creating category index pages or similar.

The issue is now being reported as fixed, with a response from Google’s John Mueller saying it was a technical issue their end. https://searchengineland.com/google-de-indexing-issue-now-fixed-result-of-technical-issues-315058

Hi Davit,

This is a widely reported problem. Fortunately it is now being reported as fixed. https://searchengineland.com/google-de-indexing-issue-now-fixed-result-of-technical-issues-315058

Hope your site soon reappears!

1. Ideally, you want to set those "Review" links to nofollow, rather than the pages they link to noindex.

2. From a quick look, the problem seems to be that lots of your links are pointing to http, rather than https, which means the link gets followed and then your site redirects the client to the https version.
For example, in your breadcrumbs, you link to the homepage but at http. I would suggest using relative links to avoid this i.e "/"
Also, I assume your product descriptions were written before you moved to https, so any links in those are http too. (https://www.twowayradiosfor.com/Motorola-RMU2080D-p/rmu2080d.htm has a link at the bottom about a discontinued product that links to a http page). I would suggest using a find and replace tool to find any reference to http://www.twowayradiosfor.com/ and replace it with https://www.twowayradiosfor.com

Also, unlikely to be causing any issues, but the AddThis tool links are HTTP too, they don't get followed when you actually click them, but that would suggest to me that your site settings are still configured to HTTP rather than https. Perhaps Site Address (URL) is wrongly configured? (That would also explain the Home breadcrumb being wrong)

As an aside, I'd seriously consider dropping the www. given the already long url. It will make your SERPs a little better in my opinion.

From what I've read, it seems to be an issue at Google's end, not something the site owners have done and therefore not something you can fix your end.

That said, interestingly, yours is the first case with reports of the exact same issue occurring multiple times over a timescale of months, most are reporting hours.

Not that that helps I'm afraid.
