Do search engines understand special/foreign characters?
-
We carry a few brands that have special foreign characters, e.g., Kühl, Lolë, but do search engines recognize special unicode characters? Obviously we would want to spend more energy optimizing keywords that potential customers can type with a keyboard, but is it worthwhile to throw in some encoded keywords and anchor text for people that copy-paste these words into a search?
Do search engines typically equate special characters to their closest English equivalent, or are "Kuhl", "Kühl" and "Kühl" three entirely different terms?
-
Thanks Tom.
While it seems that search engines generally handle these characters well I still had to ask because I did two Google searches: One for "lole" and another for "lolë", and I got very different results. On the first search my website came up on SERP page one but on the second one we were nowhere to be found on any of the first 15 pages.
Whats more, every one of the first 10 SERP pages or so contained at least one instance of the character with an accent in the title, description, or within the on-page copy. So it seems that special characters and regular ascii characters are not one in the same, or at least they are not weighted the same.
I do have to agree with you on the fact that most users will not go through the trouble entering Alt codes on their search bars. On the other hand, the fact that we barely register on SERPs for the company's DBA name might be cause for some concern.

Hi David,
Google/Bing etc. have very few problems recognising such characters in the Latin alphabet. It looks like you are mainly concerned with umlauts, which Google handles intelligently. For example...
-
Google will identify the difference between a search for "Küchen" (kitchens in German) and "Kuchen" (cake in German) and offer up relevant results. This is true in Google US and Google UK, not just localised Googles.
-
Search suggestions work just fine with these characters, and even with the standardised way of rewriting them when there is no accessible way to type them (for umlauts this is with an e following the letter). For example, in Google.de, type "Kue" and you will be given the suggestion "Küchen".
You are mainly concerned with brands, which muddies the waters a little because many people in English speaking markets won't bother/know how to type the umlauts. However, Google normally handles this well and recognises the intent.
I would recommend you ensure you consistent use the brand name with the foreign characters, as intended. Google/Bing and co. shouldn't have any problems. Which HTML encoding you use is by the by, in my opinion, as long as the characters are rendering correctly.

What does Disallow: /french-wines/?* actually do - robots.txt
Hello Mozzers - Just wondering what this robots.txt instruction means: Disallow: /french-wines/?* Does it stop Googlebot crawling and indexing URLs in that "French Wines" folder - specifically the URLs that include a question mark? Would it stop the crawling of deeper folders - e.g. /french-wines/rhone-region/ that include a question mark in their URL? I think this has been done to block URLs containing query strings. Thanks, Luke

Crawled page count in Search console
Hi Guys, I'm working on a project (premium-hookahs.nl) where I stumble upon a situation I can’t address. Attached is a screenshot of the crawled pages in Search Console. History: Doing to technical difficulties this webshop didn’t always no index filterpages resulting in thousands of duplicated pages. In reality this webshops has less than 1000 individual pages. At this point we took the following steps to result this: Noindex filterpages. Exclude those filterspages in Search Console and robots.txt. Canonical the filterpages to the relevant categoriepages. This however didn’t result in Google crawling less pages. Although the implementation wasn’t always sound (technical problems during updates) I’m sure this setup has been the same for the last two weeks. Personally I expected a drop of crawled pages but they are still sky high. Can’t imagine Google visits this site 40 times a day. To complicate the situation: We’re running an experiment to gain positions on around 250 long term searches. A few filters will be indexed (size, color, number of hoses and flavors) and three of them can be combined. This results in around 250 extra pages. Meta titles, descriptions, h1 and texts are unique as well. Questions: - Excluding in robots.txt should result in Google not crawling those pages right? - Is this number of crawled pages normal for a website with around 1000 unique pages? - What am I missing?

How to maximize CTR from Google image search?
I'm getting good, solid growth in my Google SERPs and Google search traffic now, but I do notice that 70% of my high ranking search results are images and the CTR on those is only 3-4%. All my images are illustrative and highly relevant to my travel blog, but I guess that hardly matters unless they get CTR so people see them in context. Has anyone seen or done any good research on what makes people click through on Google Image Search results? What are the key factors? How do you optimize for click-through? Is it better to watermark your images or overlay label them to increase likelihood of click-through? Thanks, Tony FYI the travel blog in question is www.asiantraveltips.com and a relevant Google search where I rank highly is "songkran 2016 phuket".

Question about Indexing of /?limit=all
Hi, i've got your SEO Suite Ultimate installed on my site (www.customlogocases.com). I've got a relatively new magento site (around 1 year). We have recently been doing some pr/seo for the category pages, for example /custom-ipad-cases/ But when I search on google, it seems that google has indexed the /custom-ipad-cases/?limit=all This /?limit=all page is one without any links, and only has a PA of 1. Whereas the standard /custom-ipad-cases/ without the /? query has a much higher pa of 20, and a couple of links pointing towards it. So therefore I would want this particular page to be the one that google indexes. And along the same logic, this page really should be able to achieve higher rankings than the /?limit=all page. Is my thinking here correct? Should I disallow all the /? now, even though these are the ones that are indexed, and the others currently are not. I'd be happy to take the hit while it figures it out, because the higher PA pages are what I ultimately am getting links to... Thoughts?

Soft Hyphenation: Influence on Search Engines
Does anyone have experience on soft hyphenation and its effects on rankings? We are planning to use in our company blog to improve the layout. Currently, every word above 4 syllable will be soft hyphenated.
Intermediate & Advanced SEO | | zeepartner
This seems to render okay in all browsers, but it might be a problem with IE9... In HTML 5, the "" soft hyphenation seems to be replaced with the <wbr> Tag (http://www.w3schools.com/html5/tag_wbr.asp) and i don't find anything else about soft-hyphenation in the specs. Any experiences or opinions about this? Do you think it affects rankings if there are a lot of soft hyphens in the text? Does it still make sense to use or would you switch to <wbr> already?0
