Best way to block a search engine from crawling a link?
-
If we have one page on our site that is is only linked to by one other page, what is the best way to block crawler access to that page?
I know we could set the link to "nofollow" and that would prevent the crawler from passing any authority, and we can set the page to "noindex" to prevent it from appearing in search results, but what is the best way to prevent the crawler from accessing that one link?

Hi there,
I'm assuming you are trying to do pagerank sculpting (or something related..) - which was made a little more tough in recent years. I'll base my answer around this assumption, so feel free to correct me if this isn't the case.
There are several methods to make a link uncrawlable:
- AJAX - Googlebot will not read any calls through AJAX. If you can load your link through an external call, it would be completely hidden.
- Javascript - Obfuscate links with Javascript that masks the link. You can do any number of solutions here, including using tags with a title of your URL, which upon clicking, goes that that URL. Simple and effective.
- Redirects - I haven't tested this last idea, and it may not work. You might be able to redirect to another page in your website, which is then set to not be indexed. Then redirect to the intended page through a query string. In theory it should work, but obviously not as good as the previous methods I described.
Let me know if you have questions. I'd be glad to help further.
Cheers!

Noindex/nofollow should be good enough, but if you want to be sure it doesn't get indexed, you could can also include <meta name="robots" content="NOINDEX, NOFOLLOW"> in the head section of the page to be blocked. You can also exclude the page in your robots.txt file. </meta name="robots">
You can find a simple robots.txt generator in Google Webmaster Tools if you need to block particular pages or directories. The robots.txt file should be in the root directory of your site and look something like this:
User-agent: * Disallow: /file-you-want-to-hide.html
You can also request removal of specific URLs in Webmaster Tools if it has already been indexed.

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

Site wide footer links vs. single link for websites we design
I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)

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 -
Does Google crawl the pages which are generated via the site's search box queries?
For example, if I search for an 'x' item in a site's search box and if the site displays a list of results based on the query, would that page be crawled? I am asking this question because this would be a URL that is non existent on the site and hence am confused as to whether Google bots would be able to find it.
