Google Penguin update – same anchor text now hurts website SEO

If you have the same anchor text in your footer links on all the websites that you create this can now hurt your website SEO. This happened to edublogs, they had to remove more than 10,000 footer links.

Another way to avoid the Penguin update penalty is by making your anchor text footer links nofollow.

Find DNS server records mx cname ttl A record rDNS

Easily find your nameserver’s records including a, mx, cname and ttl for each:
Network-tools.com

My favorite overall DNS testing tool for 2012 is intoDNS.com, which will also show your rDNS record.

DNS propagation – how long does it take for a domain to change to the new server?

The Domain Name record “propagates” as fast or slow as your TTL (time to live) setting is on your A record.

Propagation is not technically correct. It’s cached for the amount of seconds for TTL.

86,400 = 1 day (long)

14,400 = 5 hours (typical)

300 = 5 minutes (short)

Getting ready to change servers? Change it to 300, but remember to set it longer after you’re done.

Don’t want to mess with it? Set it at 14400 (no commas!)

Watch your DNS record (domain name) propagate around the world

There is a DNS cache on your local computer too, to clear it on windows ipconfig /flushdns

If your computer’s DNS server is OpenDNS, you can clear the Master OpenDNS domain name cache here.

How to tell if your website has a dedicated IP

http://www.robtex.com/ip/

Cannot see new version of website – updates not showing – sticky cache

1) Control-R (or Command-R) – Control – F5 does the same thing on Windows

2) Go through your options and empty the cache manually

3) Try another browser

Users do not normally notice the old website hasn’t changed because they are not talking to the developers and wouldn’t know when the website really has been updated. This happens all the time.

Most likely you have a “sticky cache” on your computer.

Here’s the trick: Whether you get to http://yourwebsite.com by clicking this link, or by going through google, once you see http://yourwebsite.com in the top line of Internet Explorer, Firefox or Chrome (The URL or Location bar), do a hard refresh.

Hard refresh is done when you are supposed to be seeing the new webpage that you are having trouble with, and reaching out to your keyboard, while holding the “control” key, tap and letup on the “r” key, then let go of the “control” key. (Ctrl-r)

This dumps the old cached page that is sitting on your computer and tells it to go load the new one from the internet.

This insures that you are seeing the latest changes to your website.

The “sticky cache” issue is common when developing new websites. Usually people don’t notice changed pages so much because they don’t know the page should have changed. It happens more often than people realize.

Note: If you have an alternate web browser installed that you haven’t used lately, just view the website in it, you should see the latest version automatically, since it’s not been “cached” lately. Browsers do not share each other’s cache.

If you have a really sticky cache:

Log out of WordPress, clear your browser cache, quit and restart the browser and try again. If that does not work, there may be a caching proxy or network cache somewhere between you and your host. You may need to wait for a few hours until this cache expires.

Note: CSS changes can cause a really sticky cache when background images are changed, they tend not to update unless you clear your cache.

My .htaccess tricks

To show a directory listing specifically in that directory only place this in the .htaccess file that resides in that folder:

IndexOptions -FancyIndexing
 Options +Indexes




To deny a directory listing, place this the the .htaccess in that directory or in a higher directory:

 Options -Indexes
 

Now a 403 error will be returned instead.



To redirect to a subdirectory or a folder:


RewriteEngine On
RewriteBase /
RewriteRule ^index.(.*)?$ http://domain.com/subfolder/ [r=301]

This will redirect any attempt to access a file named index.something to your subfolder, whether the file exists or not.

A simple HTML redirect is an alternative:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Your Page Title</title>
<meta http-equiv="REFRESH" content="0;url=http://www.the-domain-you-want-to-redirect-to.com"></HEAD>
<BODY>
Optional page text here.
</BODY>
</HTML>
