The beginning of SEO

Search engines are programmed to rank websites according to their popularity or relevancy within  given search parameters.  If I want my website or blog to be available to readers and/or buyers within that framework, I have to share my website contents with search engines so they can find and recommend my site to others.  Well, I don't really have to SHARE it with them.  They'll find me. Then, when someone does a search for one of my products (or for me), they can find me by doing a basic search by Google, Bing, Yahoo, or others. This can be accomplished with a process called Search Engine Optimization (SEO).  The search engines send out a crawler (Internet bot, if you will) to pick up bits of information from each website it can find.  The key, for me, as a seller, is that I need to make it super easy for these crawlers to get the right information; see that my site isn't Spam or just advertising.  It's great, and relevant, and should be put it out there high in the search engines so my "peeps" can find it.
What's important in getting my website or blog at the top of search engines, is how my website communicates and interacts with other websites and people. This includes linking to other relevant websites, social networking, reciprocal blogging or mentions, and real referrals from other sites.  It's also important to be able to communicate with other types of devices, such as tablets and mobile phones.  How easy is it to move around on my website?  Are the images so large that it takes too long to load the page?  If I'm concerned about loading speed (and we all should be), I can go to the Page Speed Analyzer here  to do an analysis of my website's speed.  This site will even tell me how I can correct the issues of slow page loads.
Got too much advertising on your page?  That will send you back down on the list.
And the number one thing to do to help  your content to get to the top of the list is to write and display GREAT CONTENT so people will go to it, read it, and tell their friends about it.  Yep, fantastic writing, images that awe, videos that go viral, and products that impress.
If you would like some more goodies on SEO, I recommend you first read the Google Webmaster Guidelines here..  Then, maybe a search on SEO is in order.

Have a great week!
