      One of my clients believes someone is trying to hack their site.  We are seeing the requests with a server protocol or HTTP 1.0 so they want to block 1.0 entirely.

      Will this cause any problems with search engines or regular, non-spamming visitors?

        i would think that most bots and modern browser all ise http 1.1 by now, but I am sure there are some things out there that still use 1.0. i seem to remember that some phones use 1.0, old windows media players
        i would try to block them anothr way just to be sure. maybe rogerbot users 1.0
        it sems a bit over kill
        They may just change to 1.1

          Ranking #1 but Bounce Rate is 90%?!

          Hi Mozers, We have a page that's ranking #1 for several very high volume queries but the bounce rate is 90%. It's puzzling that the page is ranking so well even though the bounce rate is exceedingly high. The algorithm takes user engagement metrics into account so you would think that it those metrics would push the page down. Having said that, the page does have lots of backlinks. So maybe it's ranking despite the fact that people are clicking out? Does anyone have an idea? Thanks, Yael

          LinkedIn 999 HTTP Errors

          I am working on a website, https://linkedinforbusiness.net and a ton of 999 HTTP errors have only now surfaced. I would venture from reading the "Request denied" error in the log, LinkedIn means to block BLCs attempts to check those links. It might be because the site has a lot of LinkedIn links; maybe they find it suspicious that the server is sending a lot of requests for their links. How do you see this? Any fixes? What level of harm do you think it brings to the site? I have removed all similar links to LinkedIn from my site to avoid this (https://www.hillwebcreations.com). However, this isn't so easily done for LinkedIn For Business, as her work in all about helping businesses and individuals optimize their use of LinkedIn.

On the other site we have the Product name in the H1 and no H2. Does anyone have any advise about the best information to have in the H1 and H2

          Robots.txt - Do I block Bots from crawling the non-www version if I use www.site.com ?

          my site uses is set up at http://www.site.com I have my site redirected from non- www to the www in htacess file. My question is... what should my robots.txt file look like for the non-www site? Do you block robots from crawling the site like this? Or do you leave it blank? User-agent: * Disallow: / Sitemap: http://www.morganlindsayphotography.com/sitemap.xml Sitemap: http://www.morganlindsayphotography.com/video-sitemap.xml

          Block in robots.txt instead of using canonical?

          When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt?

          Robots.txt is blocking Wordpress Pages from Googlebot?

          I have a robots.txt file on my server, which I did not develop, it was done by the web designer at the company before me. Then there is a word press plugin that generates a robots.txt file. How Do I unblock all the wordpress pages from googlebot?

          Sudden rank drop for 1 keyword

          A page of mine  (http://loginhelper.com/networks/facebook-login/) was ranking in the top 10 for keyword (facebook login) and has been for at least 2 months, moving between 5th and 10th. Suddenly in the last 3 days the rank for the keyword dropped from 7th to 46th, yet none of the other keywords have been affected (they target other pages) and their ranks have continued to improve. I am trying to figure out what caused this sudden drop in the ranking of 1 page (the page has quality mainly text based content and isn't in the least bit shallow or spammy) I have been thinking perhaps a crawl or server error may be to cause leaving the page temporarily unavailable or with a big load time... Otherwise what could cause one page to drop so much so quickly whilst other pages improved their rank?

          Does Blocking ICMP Requests Affect SEO?

          All in the title really. One of our clients came up with errors with a server header check, so I pinged them and it times out. The hosting company have told them that it's because they're blocking ICMP requests and this doesn't affect SEO at all... but I know that sometimes pinging posts, etc... can be beneficial so is this correct? Thanks, Steve.
