Windows, roofing, chimney blocks and bedbugs all get the same treatment here, which tells you what kind of site this is. Over a hundred short posts answer the practical household question somebody has just typed into a search box, and they answer it without preamble.
Some are genuinely handy. Roman shades on a timer can be set to admit the most light during a cool morning and less during a hot afternoon, which is the sort of detail that only appears when somebody bothers to write the post. Replacing a single glazed window gets explained in terms of the heat it loses rather than the price of the frame. Choosing a paving contractor becomes a question of more than the quote.
Running underneath is the author's own subject, which is online marketing. Those posts argue that a strategy has to be built for each client and each site rather than repeated, and they are the ones written from experience rather than from research.
Use this as a reference. Search for the job you are about to attempt and read that one post.
