SEO plugins like Yoast for Wordpress and in YouTube videos recommend using bold text for your keywords to improve search engine rankings. Does bolding your text actually work for SEO? What about bold anchor tags?
Does bold text really improve your search engine rankings?

Be careful! The cited link (http://moz.com/search-ranking-factors/survey) is a list of reported beliefs from SEOs. It often does not reflect reality, but rather how far afield our so-called SEO experts are while living in an echo-chamber of their own making. This yearly survey is evidence of the echo which is growing quite weary. It is no wonder why the average webmaster is confused.For a period, Google did give weight to italics and bold terms thinking that these were valuable clues, but since that too could be gamed and bold and tactic terms were used in an effort to spam search engines and to gain a disproportionate advantage, that practice ended many many years ago. Bold and italics DO NOT effect SEO except for secondary effects. The mark-up is relatively ignored and the text is weighted exactly the same as all the rest. I say relatively because I suspect that the parser/filter rule likely still exists where these terms are indexed, but that the weight is 0.Having said that, bold and italics terms can have a secondary effect of increasing engagement thus increasing the time on page and time on site metrics and possibly  pages visited and a site may see a modest increase in conversion rates as a result. However, from a marketing stand-point, this is a terrible thing to do. Another secondary effect that may exist is that keyword matches may be made against bold and italic text much like the description meta-tag is matched to search queries though I suspect that would be less likely. Even though there is no weight assigned to these terms, matches can be made given the right circumstance meaning that the pool of matches does not rise to an expected level and some lower criteria is used to make the match.You have to remember that most SEOs are parroting what they have read or heard which changes daily. So what was true 5-6 years ago still echoes about as fact when in reality, Google made the change a long time ago.As a hint for future questions such as this, ask yourself if the purported fact can be manipulated? In this case, the answer would be Yes. Bold and italics terms can be manipulated. If you find yourself answering yes, then the answer to the question of whether the purported whatever is an SEO factor is clearly No. The only exception that remains are links, title tags, header tags, image alt text, and description meta-tags. There my be a few more minor cases that have not come to mind. That is it. It truly is that simple folks.Ref: https://plus.google.com/+MarkTraphagen/posts/Ex7p2rDx2Do You will want to read this, but AJ Kohn essentially echos what I just said but shorter.
