SEO world changes rapidly, new tactics arrives in the field after every new Google algorithm version, so with the time and according to Top SEO Services guidelines we need to change our SEO strategy too. Here are some tactics which are old and you shouldn’t follow anymore:-
Congestion of keywords into the Meta Description: Meta Description is no longer used for rankings, but it can be used to display the small description below your link in search results which will show up to user and stuffing of keyword there will not attract user and search engine.
Putting a list of keywords in the page title: Stuffing of keyword is a bad tactic, you should make the page title descriptive or you should use your brand name there with significant keyword.
Optimizing Meta keywords: Nowadays there is no purpose to optimize meta keywords because search engines don’t consider them as a ranking factor at all.
Jamming keywords into heading tags: Using H1, H2, H3 tags with your targeted keyword is a good practice but you should only use them if keywords fit into these tags and make sense. You should not waste your time trying to get them into every single page.
Keywords in the alt tags of images: We all knows that search engine crawls alt tag not the image, putting a keyword there will not be a beneficial tactic while failure of loading image by browser, using descriptive alt tag while optimizing an image can give idea to user and search engine both about that image but a keyword cannot.
