So often I come across websites that use the same page title for all their pages. This is usually either the fault of a lazy designer or someone that just doesn’t understand the importance of unique page titles.
Without unique titles the search engine spiders that crawl your website will have less of a chance of understanding what the page is about as well as how to distinguish it from the rest of your site. Therefor your listing in search engine results pages (SERPS) will suffer.
In fact it’s more than just an SEO tip. When using sharing a link on many social media platforms the show the title of the page that the link goes to. If the title has nothing to do with what’s on the page, people will not know what the page is about and will be less likely to click on your link. Another example is for pay per click advertising. If you use Google Adwords Google may penalize you because it thinks your page doesn’t match the keywords you’ve selected and as a result your bids will be artificially increased.
So, Always use unique titles for each page on your website. It’s not just an SEO tip it’s a basic usability tip.
