Adding a glosssary
-
WE are adding a module to our site that will add a glossary.
It is going to add a link to the glossary where each word is used.
Should we add no follow to those? Or is there any other implication seo wise using this?
-
Now more than ever, site owners need to be extremely careful about setting up site glossaries. The shear volume of internal links can get out of hand fast, and over time, exponentially cause mass internal link confusion from an algorithmic perspective.
While I rarely (almost never) recommend bothering to try and figure out how to maximize the user of nofollow attributes, this is a rare exception, though the key is to also consider blocking the glossary from search engines altogether.
I also highly recommend reading articles Lindsay Wassell has written on robots.txt, rel=canonical, nofollow and related topics. There's a lot to consider on the best approach and she does a great job of breaking down all the alternatives, along with positive and negative impact considerations with each.

Will adding 1M (legitimate/correct) internal backlinks to an orphan page trip algo penalty?
We have a massive long tail user generated gamification strategy that has worked really well. Because of that success we haven't really been paying enough attention to SEO and in looking around caught some glaring issues. The section of our site that works as long tail goes from overview page > first classification > sub classification > specific long tail term page. Looks like we were relying on google to crawl/use forms to go from our overview page to the first classification BUT those resulting pages were orphaned - so www.mysite.com/product/category_1 defaulted back to the search page creating duplicate issues. www.mysite.com/product/category_1 and www.mysite.com/product/category_2 and www.mysite.com/product/category_3 all had duplicate content as they all reverted to the overview page. It's clear we need to make an actual breadcrumb trail and proper site taxonomy/linkage. I'm wanting to do this on just this one area first, but it's a big section with over 3M indexed "specific long tail term pages". I want to just add a simple breadcurmb trail in a sub navigation menu but doing so will literally create millions of new internal backlinks from specific term pages to their sub & parent category pages. Although we're missing the intermediary category breadcrumbs, we did have a breadcrumb coming back to the main overview page - that was tagged nofollow. So now I'm contemplating adding millions of (proper) backlinks and removing a nofollow tag from another million internal back links. All of this seems in line with "best practices" but what I have not been able to determine is if there is a proper/better way to roll these changes out so as to not trigger an algorithm penalty. I am also reticent about making too many changes too quickly but these are SEO 101 basics that need to be rectified. Is it a mistake to make good improvements too quickly? Thanks!

Ad server not indexed
Hello guys, My client is using an ad server (not sure if i am allowed to tell which one so I will not for now) installed at ads.clientsite.com. It is using noindex, nofollow for preventing Google to index it but also it is blocking like 90 000 other pages on clientsite.com to be indexed/crawled. The guy that applied the noindex tag it is no longer here so I cannot ask him about the logic behind those noindex tags. How big could be the damage to clientsite.com if I will remove the noindex tag from the ad server (ads.clientsite.com? If needed I can PM you the ad server platform we are using, Regards, Ed

Adding Location to Title Tags has dropped SEO Rankings
After adding the suburb of my business to each title tag on my website, I've noticed their rankings have dropped from page one to page four in a lot of cases. Should I wait it out and expect to see them improve in the future? Should I revert them back to their old title tags? I'm a little concerned!

Page Layout Updates and Mobile Pages with Ads
I have been trying to do some research on the Page Layout Algorithm and Top Heavy Ads and much of what I read does not mention about mobile pages as apposed to desktop. I am curious if the Page Layout updates can be effected by mobile pages as well and if there is any good articles on this subject. Also is this Algorithm been incorporated into its regular algorithm or do we still have to wait for refreshes to see the impact? Cesar

Are three Adsense ads on a long page a negative for search ranking?
I've not a site whose home page that is #1 for a popular keyword. The page is 1200 words, plus comments following. It's a clean page with no popups, and has one large rectangle Adsense ad above the fold (lots of text around this ad, and a very high percentage of page ATF is text), and another large rectangle Adsense ad that is midway down the article (after you have to page twice to get there). So, it's a very low ad to text ratio and ATF looks very clean. I have room for one more Adsense ad closer to the bottom of the article, which would be about five page downs through the page. My question is, will placing another ad way down the page affect my ranking in any negative way? I'm so pleased with my #1 ranking I hesitate to add it. But the page converts in Adsense so well, and heat maps show a large number readers do read all the way down the page, so I'd like to pick up some more ad revenue.

Would adding a line break tag into the product name affect SEO ranking and Google's ability to read the entire title?
Our client would like to include a link break so that part of the product name always showed up on a second line. Would this affect how Google bots crawl the product name? Would it also affect how Google would show the product name in a search result page? Thanks!

Information being added before meta description
On the search engine results page I am finding that information has been added before my meta description - this is only a recent flaw and I've no idea how it can be caused. It is happening in the same format as you see dates sometimes before meta descriptions. This is what is actually being shown on the search engine results page. I am getting this text - Product 1 - 15 of 18 – then my meta description after that. The words 'Product 1 - 15 of 18' is in the heading at the top of the page but it is in no way interacting with the meta description. It looks like Google is confusing the words 'Product 1 - 15 of 18' with a date possibly. Any suggestions.
