Meta title tag is very important tag for any blog post and serves as the gateway of the post. Changing meta title tag not only confuses your readers but can also hurt your existing Google ranking. In my previous post I have written about how permalink change can hurt your blog credibility.
Common SEO mistake.
One of the very common mistake that most of the non SEO experts do when we are trying to achieve better SEO for our blogs is changing blog titles for ranking higher in search engine. But it should be avoided as changing titles or permalinks etc. always hurts Google ranking. The reason being very obvious. If Google has already ranked a page, then it is due to consideration of certain on-page SEO factors. Whenever any changes made in any of these SEO factors, then the value of these factors lost their importance, hence Google and other search engines usually takes time to provide re-importance to the same page based on the newly changed factors.
You may have noticed that Google or any other search engine provides most importance to the title of any post while positioning them in the search engine ranking. That is why the most relevant title are placed towards the beginning of the search results. Once the title being changed, then Google algorithm has to re-index your post because the post or page title no more bear the same importance as previous, it may either be increased or decreased.
Google penalty.
It may appear to you that you have done better SEO for title than before and your page rank and other Google ranking factors should gets increased, but the results would not be up to your expectation. Instead it goes down for few days/months or ever. This is because it appears suspicious to Google, whenever you are trying to change something on-page that Google has already read or indexed. This is not to demoralize you but to prevent spammers to do spam activities by manipulating the Google algorithm.
So, if you have already decided to change title after publishing a blog post, then you have to be ready for facing the consequences.
Alternative way of achieving better on-page SEO without changing title.
It is better approach to do on page SEO by playing with keywords placement, using anchor keywords,keyword density etc. within the body without changing permalink, title etc. to avoid Google de- ranking.
