A lot of companies are using copyright and trademark symbols in their blog posts, not realizing the effect those symbols have on their SEO.
If you use the ©, ™, or ® symbols in your blog post titles, or even the first 500 characters of your blog posts, that’s what Google will think your site is about. Those characters become part of the word, like Ke$ha or “Big $aving$,” and are harder to find without them.
If you have the phrase Super-Mega-Global© Electric Socks™ in your website or blog post title, Google will think the actual keywords are “Super-Mega-Global©” and “Electric Socks™.”
Honestly, when’s the last time you ever did a search for ™?
Never. And neither does anyone else.
I realize you want to protect your trademark and brand, but you’re not doing yourself any favors by using the symbols in your posts or pages. Your primary goal for a website/blog is to be found by the search engines, not to satisfy the ticky-tack tics of the company lawyer.
There is plenty of room at the bottom of the blog posts, especially if you stick in a paragraph of boilerplate language at the bottom of the post.
Just make sure you use the <small> tags on them.
