Lots of duplicates

Hi,

Well, I now see the canonical URL tag in the header of your page:

That means that even if the URL brands.html?limitstart_category=0&limit=12&limit=12&limit=12&limit=12&limit=12&limit=12&limit=12&limit=12 is crawled by a search engine, it will only index the canonical URL and users searching for things on the search engine will only see the canonical URL.
So I think it's fine like that.

Hi,

Well, that means that the crawler has a problem.
It shouldn't hog all the resources of the server.
Search engines' crawlers don't do that.

Hi,

Finally, you provided some information on how you got that URL.
So I went and downloaded that tool called "Screaming Frog SEO Spider" and ran it on the URL /products/katalog/furnitura-dlya-dverej.html of your website.
I did get URLs with two "limit" parameters when it shouldn't happen, but not more as the tool is limited to 500 URLs in its free version.
What I learned is that these URLs with the extra limit parameter come from the rel="prev" and rel="next" meta tags of the products/katalog/furnitura-dlya-dverej.html?limitstart_category=12&limit=12 page :

However, as far as I know, HikaShop doesn't add these meta tags to the pages:

I'm thinking you're using a SEO plugin which does that.

I also just used alphacrawler.pro/ on your website and didn't see any problem regarding this issue. So maybe using another tool would help.

But maybe the thing adding the rel tags need to be fixed on your end.

In any case, whether the SEO crawler you're using is at fault or the SEO plugin adding the rel tags is at fault, it doesn't seem to be something we can do anything about on our end.

Hi,

Thanks. With that tool, I was finally able to properly reproduce the problem and I think I found what is going on.
Change the code:

		elseif($ret_start && !$ret_limit)
			return $current_url . '&limit='.$this->limit;

elseif($ret_start && !$ret_limit) {
			if(strpos($current_url, '&limit='.$this->limit)) {
				return $current_url;
			}
			return $current_url . '&limit='.$this->limit;
		}

Hi,

could you fix it so that 1 page was without tails like: ?limitstart_category=0&limit=12

When I scan another such url is visible

return $current_url.$sep.'limitstart'.$this->hikaSuffix.'='.$start.'&limit='.$this->limit;

$return_url = $current_url.$sep.'limitstart'.$this->hikaSuffix.'='.$start;
		if(strpos($return_url, '&limit='.$this->limit)) {
			return $return_url;
		}
		return $return_url.'&limit='.$this->limit;

Hi,

The patch I provided is for the URL

/products/katalog/furnitura-dlya-dverej.html?limitstart_category=0&limit=12&limitstart=96&limit=12

Hi,

Almost anything is possible in programing if you spend enough time and money on a problem.

It's possible to change that. However, it's not easy. The code which modifies the current URL to generate the URLs of the pagination can potentially remove the limitstart parameter if it's 0, but removing the limit parameter when its 12 would be quite difficult as the pagination system doesn't know what is the default limit of the current listing.
That would probably require hours of work to make a first solution, and even so, it would probably have negative and unforseen side effects which will take again hours of work to fix.
On the positive side, even if we did that work, it wouldn't change anything since there is already a canonical URL on the page which discards the URL of the pagination when search engines crawl your website.

That's why I answered you :

No. This is normal. It's not a mistake and it doesn't have any negative impact.
