SEO Terms That You Need To Know
SEO terms can be downright confusing. Here's a list I've put together of what you'll run across again and again. I'll add and subtract from this page as needed.
200 - OK; the request for the web page/post was successfully executed.
301 - URL has been permanently moved (redirected). Think of it like a change of address post card when you move from one location to another. This is best for passing any Google page rank from one URL to the next. Here are two examples of 301 redirects; click here to see a whole lot more that are really cool!
Redirect a single page:
Redirect 301 /pagename.php http://www.domain.com/pagename.html
Redirect an entire site:
Redirect 301 / http://www.domain.com/
302 - The URL has been temporarily moved. Typically used for A/B split testing, although I've seen it used as a permanent redirect. Google says it doesn't make any difference, but I'm old school, so I like to use these codes for their intended purpose as they were originally created.
Redirect /product.php http://www.example.com/promo.php
404 - the URL can't be found. It could be a lot of different reasons why. Sometimes they're temporary, but at other times they're an indicator of broken links or missing pages. Investigate and resolve.
410 - This is really useful! If you really want to permanently delete a page from your web hosting server, please use this code and command to let the search engine crawlers know they shouldn't waste anymore time looking for this URL, because it's looooong gone. A sample command is below; here's the reference I used.
RewriteRule ^example-html-filename-1.html$ - [G,NC]
Algorithm - Basically, it's a formula written by computer scientists and programmers that contain ranking factors to determine how relevant and authoritative a page or post is for a keyword query. They're all more secret than where the U.S. government has stashed captured aliens (this is a joke; please don't take it seriously). They are not known, because if everything in the algorithm was known by only a few people, the rest of us poor slobs wouldn't ever stand a chance of ranking for anything.
By no means is this the complete list. I have several dozen more to go through. I'll add a few every week.
